[PATCH 1/2] nut: Update to version 2.8.3

[Adolf Belka <adolf.belka@ipfire.org>]

- Update from version 2.8.2 to 2.8.3
- Update of rootfile
- This update has an sobump and this requires collectd to be shipped. Another patch will
   be submitted for that together with this one.
- Changelog
    2.8.3
 - Fix fallout of development in NUT v2.8.0 and/or v2.8.1 and/or v2.8.2:
   * Move of `NUT_DEBUG_LEVEL` and "-D" CLI option handling to start of
     driver programs for issue #2259 in NUT v2.8.2 release misfired with
     regard to data-dump mode (it no longer caused foreground by default).
     [#2408]
   * The `nut-driver-enumerator.sh` improvements misfired in v2.8.2 release
     with an overlooked bit of shell syntax, and caused `nut-driver@upsname`
     instances to not auto-restart when `ups.conf` is edited. [#682, #2410]
   * Addition of "NUT Simulated devices" support to `nut-scanner` in v2.8.2
     broke detection of (in-)ability to find and query "Old NUT" servers via
     `libupsclient.so` (internal flag got always enabled). [#2246]
   * A fix for `upsmon` v2.8.1 setting of `OFFDURATION` [PR #2108, issue #2104,
     revisiting PR #2055, issue #2044] was overly zealous and impacted also
     the `OB` state in cases where communications to the data server were
     severed and `DEADTIME` setting was not honored. [PR #2462, issue #2454]
   * Using `drivername -c reload` (e.g. facilitated by `nut-driver-enumerator`
     script and service when editing `ups.conf`) led to disconnected Unix
     sockets and a tight polling loop that hogged CPU. While the underlying
     bug is ancient, it took recent development to hit it as a practical
     regression. [issue #1904, issue #2484]
   * Fallback `localtime_r()` and `gmtime_r()` for some platform builds where
     a `*_s()` variant was available was not handled correctly. [PR #2583]
   * A recently introduced `allow_killpower` did not actually work as an
     `ups.conf` flag (only as a protocol command). [issue #2605, PR #2606]
   * The ability of two copies of the driver program to talk to each other
     with `upsdrvquery.c` code was not complete for the case of indefinite
     `select()` wait timeout. Now `upsdrvquery_read_timeout()` fixed private
     use of `struct timeval={-1,-1}` as a trigger to `select(..., NULL)`,
     as logged in one part of code and not handled in the other, for the
     indefinite wait [#1922, #2392, #2686, #2670]
   * The `disable_fix_report_desc` option introduced for `usbhid-ups` driver
     since NUT v2.8.1 was not applied for early dialog with the device while
     its report descriptors were being discovered. Now this flag, as well as
     `interruptsize` and `interruptonly`, are considered before we first try
     to open the USB device handle. [#1575, #1512]
   * In `cps_fix_report_desc()` we intended to fix-up input and output voltages
     in certain cases against high voltage transfer, we only fixed-up one of
     them. [#1245]
   * `upsd` should now handle `TRACKING` value of `STAT_CONVERSION_FAILED`
     introduced in NUT v2.8.2 for the socket protocol (between driver and
     data server), by returning "ERR INVALID-ARGUMENT", so there is no change
     for the network protocol definition. [#2182]
   * The `configure --enable-inplace-runtime` option added in NUT v2.8.1 should
     now also try to detect and set default values for the `--with-drvpath`,
     `--with-cgipath`, `--datadir` and `--libdir` options to more closely match
     a packaged setup and avoid confusion with e.g. two incompatible NUT client
     libraries in system default search path. [#2895]
 - Large parts of the NUT User Manual and NUT Developer Guide were relocated
   into the new NUT Quality Assurance and Build Automation Guide (maintained
   in `docs/qa-guide.adoc`), accompanied by new chapters written and detailed
   for this subject; the chapter about `ci_build.sh` script became a separate
   `ci_build.adoc` document included into the new document. Overall, this guide
   intended to help the current and future maintainers of NUT itself, as well
   as to inspire any other projects that investigate similar solutions. [#2832]
 - SEMVER, know thyself!
   * Development iterations of NUT should now identify with not only the
     semantic version of a preceding release, but with git-derived information
     about the amount of iterations that followed (if available):
     the three-number "semver" would be seen on release snapshots, while
     other builds would expose the added components: one with the amount
     of commits on the main development trunk since the preceding release
     which are ancestors of the built code base, and in case of feature
     development branches -- another component with the amount of commits
     unique to this branch (which are not part of the development trunk yet).
     This allows to produce more relevant (monotonously growing) version
     identifiers for packages and similar artifacts, with more meaningful
     upgrades via development snapshots, eventually. A copy of the current
     version information would be embedded into "dist" archives as a
     `VERSION_DEFAULT` file, among provisions for packager tuning. [#1949]
   * Documentation about this would be maintained in `docs/nut-versioning.adoc`
   * SMF manifests and systemd units now refer to man pages and their online
     variants under `NUT_WEBSITE_BASE` dependent on codebase maturity
     (development or release snapshot); many programs now display such
     references in their command-line usage help, method `suggest_doc_links()`
     was introduced for this purpose. [issue #722, PR #2733]
 - A technologically and practically interesting revamp of NUT mesh of
   https://www.gnu.org/software/automake/ GNU Automake (`Makefile.am`)
   recipes was completed, allowing for a more parallelizable build routine
   on multi-CPU machines -- utilizing more cores and completing in less
   "wall-clock" time that the standard `SUBDIRS` driven approach -- when
   running `make -j (N)` from the project root directory to build everything
   enabled by the `configure` script.
   This was tested with several (GNU, BSD, Sun) implementations of the
   "make" program on the few dozen platforms that NUT CI farm tests on.
   Notably, GNU make 4.x and newer seems to process parallel high-level
   goals and sub-`make` runs better than the competition (including GNU
   make 3.x).
   It is not a radical rewrite like some other research suggested, and so retains
   the general structure and certain benefits and flexibility of that standard
   `automake` approach, including developer build workflows with a bespoke
   `Makefile` in every significant directory.  This also retains (and builds
   upon) the benefits of older work done in NUT, for builds in one directory
   to depend on libraries and other artifacts built (once) in another.
   Overall, NUT CI farm build times got 25%+ shorter (which is important as
   some scenarios had hit the 1-hour timeout imposed by providers of free
   CI hosting coupled with the weak machines provided in their free layer),
   and we suppose this is an interesting case for other projects to draw
   inspiration from for their recipe refactoring. [PR #2825]
 - As an aid for developers and maintainers, a new spell-checking recipe was
   added to first run non-interactive spelling checks in parallel, and *only*
   if something fails -- run an interactive check to edit the text and/or the
   dictionary file. The `make spellcheck` rule now also benefits from the
   rewritten recipes, as detailed above, to visit directories with text files
   in parallel. Overall, these changes may save time on multi-CPU systems, if
   compared to a sequential walk of all texts (or their directories) as was
   done before. [#2871]
 - The `make dist` goal now takes more care to require availability of the man
   pages to put into the prepared distribution archive. These may come either
   from the current build, or inherited from its sources (if using a tarball
   initially) on a platform without tooling required for man page generation.
   This requirement compromises usability of `make distcheck` on platforms without
   such tools from sources without pre-built man pages (e.g. builds from git),
   so a couple of new goals were introduced in PR #2842:
   - `make distcheck-fake-man` generates placeholder files named like pre-built
      man pages for any missing files, just for the purpose of constructing
      a sane-looking dist archive to `distcheck` strictly otherwise;
   - `make distcheck-ci` is routed to `distcheck` or `distcheck-fake-man`
     based on build circumstances (ability to build man pages or presence
     of pre-built pages, or lack of either);
   - Similarly, `make dist-ci` is routed to provide a strict or faked tarball;
   - Earlier defined goals like `distcheck-light` or `distcheck-valgrind` now
     take advantage of these mechanisms to also produce usable dist archives
     for their relaxed or purpose-specific tests.
 - Revised behaviors for the `upsnotify()` common code introduced in recent NUT
   releases (integrating with service management frameworks, etc.):
   * It was a bit cryptic when it reported a *failure to notify* (e.g. when a
     NUT program was not running as a service currently), fixed now to report
     human-friendly text instead of internal enum codes. Follow-up to [issue
     #1590, PR #1777, PR #2136]
   * Drivers should no longer print warning messages about not-initializing
     the notification subsystem because not running as a service when they
     are either started explicitly to show the help message, or when their
     CLI arguments are fatally wrong (no UPS name, no `port`, invalid trailing
     keywords...)
   * NUT programs generally should default to not "spam" about lack of known
     notification technology if our first message to be suppressed is already
     about stopping that program.  This might help nag distros into getting
     a service framework, or integrating theirs with NUT, but is generally
     annoying to end-users where there's little they can do about it (other
     than suppressing the message with `NUT_QUIET_INIT_UPSNOTIFY` envvar).
 - Drivers, `upsd`, `upsmon`: reduce "scary noise" about failure to `fopen()`
   the PID file (which most of the time means that no previous instance of
   the daemon was running to potentially conflict with), especially useless
   since in recent NUT releases the verdicts from `sendsignal*()` methods
   are analyzed and lead to layman worded situation reports in these programs.
   [issue #1782, PR #2384]
 - Drivers started with the `-FF` command-line option (e.g. wrapped into the
   systemd units to stay "foregrounded" *and* save a PID file anyway) should
   now also handle an existing PID file to interact with the earlier instance
   of the driver program, if still running (e.g. started manually). [#2384]
 - Drivers executed to force an UPS shutdown (with `-k` CLI option) should
   now try harder to kill off a daemonized sibling, if it still runs (and
   did not handle a `driver.killpower` INSTCMD well). [#2666]
 - Extended instant commands for driver reloading with a `driver.exit`
   command for a protocol equivalent of sending a `SIGTERM`, e.g. when
   a newer instance of the driver program tries to start. [#1903, #2392]
 - A new `NUT_QUIET_INIT_BANNER` envvar (presence or "true" value) can now
   prevent the tool name and NUT version banner from being unilaterally
   printed out when NUT programs start. [issues #1789 vs. #316; #2573]
 - Drivers would now report the socket they are listening on, and server
   would report full path to the driver socket it tries to connect to.
   A new `NUT_QUIET_INIT_LISTENER` envvar (presence or "true" value) can
   prevent the socket name from being unilaterally printed out when NUT
   drivers start. [#2764]
 - The `upsdrvctl` tool improvements:
   * It should now warn if executed on systems where NUT was built with
     support for service management frameworks like systemd or SMF, so
     nut-driver service units prepared by `nut-driver-enumerator` would
     conflict with manually-executed driver programs. This warning can
     be hushed by exporting a `NUT_QUIET_INIT_NDE_WARNING` environment
     variable with any value.
   * Extended `upsdrvctl` with a `list` operation (or `-l` option) to report
     manageable device configuration names (possible `<ups>` arguments to
     `start`, `stop` etc. operations), or to confirm a single name that it
     is known, and a `status` operation for more information. [#2567]
   * Fixed support of `maxstartdelay` at the level of driver section in
     `ups.conf`; added support of `maxretry` and `retrydelay` at this
     level; bumped the default `maxstartdelay` from 45 to 75 seconds to
     accommodate for longer device initialization (e.g. due to support of
     more Megatec Qx dialects by `nutdrv_qx`). [#2885, #2888]
 - `riello_ser` updates:
   * Added `localcalculation` option to compute `battery.runtime` and
     `battery.charge` if the device provides bogus values [issue #2390,
     following in the footsteps of #1692, #1685 done for `riello_usb`]
     (similar to `runtimecal` in some other drivers, may be refactored
     to that configuration and logic model in later NUT releases)
 - `apcsmart` updates:
   * Revised code to use `strncpy()` and avoid potential overflows that are
     possible with `strcpy()` used before. [PR #2564]
   * Lost communications led to a logging flood, should not anymore.
     In fact, the driver should try fully reconnecting upon getting into
     a prolonged data stale condition. [issue #704, PR #2564]
 - `nutdrv_qx` updates:
   * Added Visench C1K (using serial port converter with USB ID `1a86:7523`)
     as known supported by `nutdrv_qx` (Megatec protocol) since at least
     NUT v2.7.4 release. [#2395]
   * Introduced `innovart31` protocol support for Innova RT 3/1 UPSes. [#2712, #2798]
   * Introduced `q2` and `q6` protocol support; currently also based/tested
     on Innova devices, but other models than RT 3/1. [#2798]
   * Introduced a `gtec` subdriver and protocol, tested over USB with a
     Gtec ZP120N device. [#2818]
   * Fixed `hunnox_protocol()` to honour the optional `novendor` setting for
     devices that are confused by such query, e.g. DEXP LCD EURO 1200VA. [#2839]
   * Extended Voltronic protocol to support longer numbers as remaining
     `battery.runtime` value. [#2765]
 - GPIO drivers:
   * Extended to support library API of not only libgpiod v1.x releases,
     but also v2.x; introduced a NUT `WITH_LIBGPIO_VERSION` C macro (in
     `config.h`) to differentiate the library variants. [issue #2833]
 - New NUT drivers:
   * `bicker_ser`: added new driver for Bicker 12/24Vdc UPS via RS-232 serial
     communication protocol, which supports any UPS shipped with the PSZ-1053
     extension module. [PR #2448]
   * `liebert-gxe`: added new driver with support for Liebert GXE Series UPS
     (serial or USB posing as a serial port). [#2629]
   * `nhs_ser`: added new driver for numerous NHS Nobreaks, senoidal line -- UPS
     models with serial port, made by NHS Sistemas Eletronicos LTDA and popular
     in Brazil. Currently this driver only builds on Linux. [#2692]
   * `phoenixcontact_modbus` driver: Introduced Phoenix Contact QUINT4-UPS/24DC
     management (only new modbus addresses). [#2689, #2716]
 - Added `scripts/external_apis` with an example script integrating a
   non-native protocol with NUT (as live-stream input for `dummy-ups`
   NUT driver to publish further); that example can be installed using
   `configure --enable-extapi-enphase`. [issue #2807, PR #2813]
 - `usbhid-ups` and `netxml-ups` updated to handle "No battery installed!"
   alarm also to set the `RB` (Replace Battery) value in `ups.status`.
   This may cause dual triggering of notifications (as an `ALARM` generally
   and as an important `REPLBATT` status in particular) in `upsmon`, but
   better safe than sorry. [#415]
 - `usbhid-ups` updates:
   * Support of the `onlinedischarge_log_throttle_hovercharge` in the NUT
     v2.8.2 release was found to be incomplete. [#2423, follow-up to #2215]
   * Added support for `interrupt_pipe_no_events_tolerance=N` setting to
     optionally prevent UPS lockup, indicated by continuous "Got 0 HID Objects"
     situation as a clue, by reconnecting on stale data.  Note that while some
     devices just report information upon subsequent poll and just have nothing
     urgent to declare with an USB interrupt, others (e.g. APC BXnnnnMI) were
     seen to lock up until a full connection restart. [#2671, #2681]
   * Added support for `lbrb_log_delay_sec=N` setting to delay propagation of
     `LB` or `LB+RB` state (buggy with APC BXnnnnMI devices circa 2023-2024).
     This may work better with flags like `onlinedischarge_calibration` and
     `lbrb_log_delay_without_calibrating` for some devices. [#2347]
   * General suggestion from `possibly_supported()` message method for devices
     with VendorID=`0x06da` (Phoenixtec), seen in some models supported by
     MGE HID or Liebert HID, updated to suggest trying `nutdrv_qx`. [#334]
   * MGE HID list of `mge_model_names[]` was extended for Eaton 9E, 5PX and 5SC
     series (largely guessing, feedback and PRs for adaptation to actual
     string values reported by devices via USB are welcome), so these devices
     would now report `battery.voltage` and `battery.voltage.nominal`.
     Also a device from 5S series (5S1200AU) was tested, although it identifies
     as an "Ellipse PRO" in USB metadata. [#2380]
   * Added `ups.beeper.status` support for Masterpower MF-UPS650VA using the
     MGE HID subdriver. [#2662]
   * Added basic support for EcoFlow River 3 Plus and Delta 3 Plus models.
     [issue #2735, PRs #2740, #2837]
   * Added support for `0x09D6:0x0001` devices using the MGE HID subdriver
     assuming devices made by KSTAR (alternately using MGE vendor ID). [#2661]
   * `powercom-hid` subdriver sent UPS shutdown commands in wrong byte order,
     at least for devices currently in the field. A toggle was added to set
     the old behavior (if some devices do need it), while a fix is applied
     by default: `powercom_sdcmd_byte_order_fallback`. [PR #2480]
   * `cps-hid` subdriver now supports more variables, as available on e.g.
     CP1350EPFCLCD model, including temperature. [PRs #2540, #2711]
   * Loudly suggest to set `pollonly` flag and default a shorter `pollfreq`
     for CPS devices, to try avoiding device-driven timeouts. [#1689]
     Also adjust default `offdelay` and `ondelay` to reasonable values,
     and warn the users with CPS devices if their configured values are
     not multiples of 60. [#432, #1394]
   * In `cps-hid` subdriver, `cps_fix_report_desc()` method should now handle
     mismatched `LogMax` ranges for input and output voltages, whose USB Report
     Descriptors are wrongly encoded by some firmware versions. [#1512]
   * In `cps-hid` subdriver, try to fix frequency scaling based on the values
     we see from the device and/or configuration overrides (low, nominal, high)
     so `499.0 Hz` reading that comes from some firmware versions gets reported
     properly as `49.9Hz`. [#2717]
   * USB parameters (per `usb_communication_subdriver_t`) are now set back to
     their default values during enumeration after probing each subdriver.
     Having an unrelated device connected with a VID:PID matching the
     `arduino-hid` subdriver prevented use of an actual `usb-hid` device due to
     changes made to this struct during probe. [#2611]
 - USB-capable drivers generally:
   * ...could earlier log `(nut_)libusb_get_string: Success` due to either
     reading an empty string or getting a success code `0` from libusb.
     This difference should now be better logged, and not into syslog. [#2399]
   * ...now can benefit from a new `nut_usb_get_string()` method which can do a
     fallback `en_US` query for devices which report a broken "langid" language
     identifier value. This notably manifested in inability to query the device
     Manufacturer, Model and Serial Number values with some buggy device firmware
     or hardware. [PR #2604, issues #1925, #414]
     * Currently this was tested to fix certain device discovery with the
       `usbhid-ups` driver; but should also apply out of the box to same
       discovery logic in `blazer_usb`, `nutdrv_qx`, `riello_usb` and
       `tripplite_usb` drivers.
     * Also applied to `nut-scanner` and `libnutscan`. [issue #2615]
     * More work may be needed for other USB-capable drivers (`richcomm_usb`,
       `nutdrv_atcl_usb`) and for general code to collect string readings and
       other data points, and to configure the fallback locale or choose one
       if several are served by the device. [issues #2613, #2614, #2615]
   * ...should now be more likely to succeed with iterative detection
     of an UPS interface on a composite USB device or when looking at devices
     with non-default interface/endpoint/config numbers. [PR #2611]
   * ...should now accept a `LIBUSB_DEBUG=INTEGER` setting in `ups.conf`
     (as well as an environment variable that can be generally set via
     `nut.conf` or service unit methods or init script), to enable
     troubleshooting of LibUSB itself. [issue #2616]
   * ...should now not log "insufficient permissions on everything" alone when
     some devices were accessible but just did not match -- clarify that case
     in the next line, when applicable. [PR #2699]
   * ...should now track the fact of `assumed_LogMax` (typically when firmware
     encoding logic is wrong, and `-1` is resolved by parser). [#1512, #1040]
 - `snmp-ups` updates:
   * Added support to monitor BayTech RPC3-NC PDUs, with `baytech-rpc3nc-mib`
     serving same basic data points as were available in `baytech-mib.c`,
     but checking for a different model OID subtree and different OIDs for
     the device model information. [#2779]
   * Fixed `netvision-mib`: sync `netvision_output_info` with currently
     available `SOCOMECUPS-MIB.txt`. [#2803]
 - `mge-utalk` driver will no longer set non-standard status values `COMMFAULT`
   and `ALARM` (for a specific status bit); instead, it will set modern
   `ups.alarm` with values `COMMFAULT` and/or `DEVICEALARM` (and raise
   an `ALARM` in `ups.status` for either, as standard alarms go). [#2708]
 - Introduced a new driver concept for interaction with OS-reported hardware
   monitoring readings. Currently instantiated as `hwmon_ina219` specifically
   made for Texas Instruments INA219 chip as exposed in the Linux "hwmon"
   subsystem of its "sysfs" interface (and talking I2C under the hood), this
   approach seems to have good potential to expand into covering more devices
   and perhaps platforms. [#2430]
 - Introduced `ECO` status concept for "ECO mode" (or "High Efficiency" mode,
   or "Energy Saver System"...) as named and defined by hardware vendors.
   One common aspect is that this is a balance of electrical efficiency vs.
   robust outage protection (which may be overkill for IT equipment whose
   PSU can survive several milliseconds on capacitors alone) which can be
   selected at run-time.  Previously such choice was made at the time of
   purchase, with the UPSes only supporting some one protection strategy.
   [issue #2495, PR #2637]
   * Updated documentation, end-user clients (CGI, NUT-Monitor UI);
   * Updated `upsmon` client with ability to report entering and exiting
     the ECO mode if reported by the driver;
   * Initial implementation for Eaton devices with `usbhid-ups` driver.
 - Introduced handling for the `ALARM` status, which already existed as a
   common denominator for devices seen with active `ups.alarm` variables.
   UPS devices in an `ALARM` status are generally considered volatile and
   may be considered critical/dead by the `upsmon` client earlier than in
   other statuses (e.g. in no-communication situations). It has to be noted
   that there is no common standard for what constitutes an alarm and such
   alarm states were also previously observed for less severe reasons. This
   depends on the manufacturer/device-specific implementation in the driver.
   [issues #415, #2657, PR #2658]
   * Updated documentation, end-user clients (CGI, NUT-Monitor UI);
   * Updated `upsmon` client with ability to report entering and exiting
     the ALARM status if reported by the driver;
   * Updated `upsmon` client with setting to toggle whether an `ALARM`
     status can prompt the UPS to become critical in certain situations.
 - The `upsmon` client can now also report entering and exiting the `OVER`
   (UPS overloaded), `TRIM` and `BOOST` (adjusting for bad input voltage)
   states. A setting `OVERDURATION` was introduced to define a timeout
   after which a non-communicating UPS that was last seen in state `OVER`
   should be considered critical (or not). [PR #1074, issue #2877]
 - Revised `upssched` timer handler that can be called from `upsmon` as its
   `NOTIFYCMD` to not report confusing environment variable values of
   `NOTIFYTYPE` and `UPSNAME` from the original call when a timer eventually
   fires -- these values are irrelevant at that distant future. The NIT (NUT
   Integration Tests) suite was extended to configure and call this tool,
   facilitating its development and troubleshooting. Also the `upssched`
   timer daemon part can now save its PID file (so that NIT can terminate
   it after tests). [#2890]
 - New `libupsclient` API methods added:
   * `upscli_str_add_unique_token()` and `upscli_str_contains_token()`,
     to help C NUT clients process `ups.status` and similarly structured
     strings same way as NUT core code base. [#2852, #2859]
   * `upscli_connect()` was previously always blocking; now this is sort of
     optional, with new `upscli_set_default_connect_timeout()` able to change
     the implicit timeout from default zero (meaning blocking) to a positive
     value (or back to 0). Several NUT clients (`upsc`, `upscmd`, `upsrw`,
     `upslog`, `upsmon`, `upsimage`, `upsset` and `upsstats`) were updated
     to default with a 10-second timeout in case of name resolution lags or
     unresponsive hosts (notably a problem with `upsmon` contacting many
     remote systems at once). The `NUT_DEFAULT_CONNECT_TIMEOUT` environment
     variable can be used to modify this timeout for all clients. Further
     new methods here include `upscli_get_default_connect_timeout()` to
     retrieve a copy of the last stored timeout, and
     `upscli_init_default_connect_timeout()` to initialize the value from
     a number of sources with different priorities. [#2847]
   * Symbols exported from `libupsclient` now include `nut_debug_level*` so
     that NUT clients can be usefully debugged (e.g. using `NUT_DEBUG_LEVEL`
     environment variable). [#2847]
 - Several NUT clients including `upscmd`, `upsrw`, `upsimage`, `upsset`,
   `upsstats`, and `upslog` (during reconnection), did not `UPSCLI_CONN_TRYSSL`
   so went plaintext even when secure connections were possible. Fixed to at
   least try being secure, same way as `upsc` does for a long time. [#2847]
 - `upsmon` updates:
   * It was realized that the `POWERDOWNFLAG` must be explicitly set in the
     configuration file, there is no built-in default in the binary program
     (the settings facilitated by the `configure` script during build "only"
     impact the `upsmon.conf.sample`, init-scripts and similar files generated
     from templates). [issue #321, PR #2383]
   * Added an `OBLBDURATION` (seconds) setting to optionally delay raising
     the alarm for immediate shutdown in critical situation. [#321]
   * Optimized `parse_status()` by not checking further strings if we had
     a match; report unexpected tokens in debug log. [#415]
   * Revised internal `do_notify()` method to support formatting strings
     with two `%s` placeholders, to use if certain use-cases pass any extra
     information (e.g. not just "we have alarms" but their values too). [#415]
   * Introduced handling for "unknown" `ups.status` tokens, reporting them
     as "OTHER" notification type (whenever the set of such tokens appears
     or changes) or "NOTOTHER" when they disappear. [#415]
 - `upslog` updates:
   * Added support for limiting the loop count. Using in NIT (NUT Integration
     Test) suite for double profit (checking the tool and fallback in NIT).
   * If you use the legacy CLI options for single-system logging (`-s <system>`
     and `-l <logfile>`) along with newer tuple(s) for multiple-system logging
     (repeatable `-m <system,logfile>`), previously the single-system options
     were overridden by the tuple(s); now they become part of the list.
   * Internally, changed from use of shared global variables to query one UPS
     at a time, populated from the new list of tuples during each loop cycle,
     to passing and using the new tuple structures directly.
   * The `upsname` in the `system=upsname[@hostname[:port]]` parameter may
     be an asterisk `*` to query for devices currently served by the hostname.
   * Same log file may safely be used in different logging tuples (it is
     then recommended to use `%UPSHOST%` in a custom formatting string).
   * Fixed printing of `%UPSHOST%` when multiple systems are being logged.
   * A `%t` for a TAB character can now be used in the formatting string.
   * Added `-N` to prefix `%UPSHOST%%t` before the format string (whether
     default or custom). Useful when logging many systems into same target.
   * Added `-D` for debugging (and foregrounding by default), like with
     other NUT daemons.
   * Added systemd and SMF service integration. [#1803]
 - More systemd integration:
   * Introduced a `nut-sleep.service` unit which stops `nut.target` when a
     system sleep was requested, and starts it when the sleep is finished.
     This helps avoid NUT shutting down a woken-up system just because its
     power state was critical before the sleep (called as a `SHUTDOWNCMD`
     implementation by the end-user), and a next-read timestamp was not seen
     (deemed to be a stale UPS, meaning lost communications during critical
     state, so must go down ASAP). While not as elegant as native systemd
     "inhibitor interface" support, this approach does work. [#1833, #1070]
   * Introduced support for the "inhibitor interface" as well (should be
     available on systems with systemd version 183 or newer) for a better
     handling of the time jump specifically in the `upsmon` client via new
     `Inhibit()` method in `common.c`. [#1070]
   * As an extension of the logic introduced above, hopefully now `upsmon`
     would behave better in face of any significant and unexpected clock
     jumps (on POSIX builds so far), even if they are not suspend/hibernate
     events (or they were but we could not have an inhibit lock). Now they
     should be handled similar (avoid stale UPS data and rash decisions)
     for summer/winter time change on non-UTC deployments, a debugger
     suspending the `upsmon` process, etc. [#2597]
   * Introduced delivery of default systemd presets (lists of enabled/disabled
     units). [#2721]
   * A `nut-udev-settle.service` was introduced to replace dependency on the
     `systemd-udev-settle.service` which is deprecated and causes warnings on
     some systems. It was shown to benefit NUT use-cases however. [#2638]
 - `gamatronic` driver revised for safer memory operations; this was reported
   to have fixed a Segmentation Fault seen in earlier NUT releases with
   some of the devices supported by this driver. [#2427]
 - `upsd` updates:
   * `upsd_cleanup()` is now traced, to more easily see that the daemon is
     exiting (and/or start-up has aborted due to configuration or run-time
     issues). Warning about "world readable" files clarified. [#2417]
   * Failure to `LISTEN` on an invalid host name (e.g. `localhost:3493` or
     `1.2.3.4/24`) is now logged in a more actionable manner. [#2665]
 - `nut-scanner` updates:
   * The tool relies on dynamic loading of shared objects (library files)
     orchestrated at run-time rather than pre-compiled, to avoid excessively
     huge package footprints. This however relies on knowing (or sufficiently
     safely guessing) the library file names to use, and short `libname.so`
     is not ubiquitously available. With the new `m4` macro `AX_REALPATH_LIB`
     we can store and try to use the file name which was present on the build
     system, while we search for a suitable library. [#2431]
	NOTE: A different but functionally equivalent trick is done for `libupsclient`
	during a NUT build.
   * Fixed support for IPv6 addresses (passed in square brackets) for both
     `-s` start/`-e` end command-line options, and for `-m cidr/mask` option.
     [issue #2512, PR #2518]
   * Newly added support to scan several IP addresses (single or ranges)
     with the same call, by repeating command-line options; also `-m auto{,4,6}`
     can be specified (once) to select IP (all, IPv4, IPv6) address ranges of
     configured local network interfaces.
     An `/ADDRLEN` suffix can be added to the option, to filter out discovered
     subnets with too many bits available for the host address part (avoiding
     millions of scans in the extreme cases).
     [issue #2244, issue #2511, PR #2509, PR #2513, PR #2517]
   * Implemented parallel scanning for IPMI bus, otherwise default scan for
     all supported buses with `-m auto` takes unbearably long. [#2523]
   * Bumped version of `libnutscan` to 2.6.0, it now includes a few more
     methods and symbols from `libcommon`. [issue #2244, PR #2509]
   * Do not actively suggest `vendor(id)`, `product(id)`, and `serial` options
     for `bcmxcp_usb`, `richcomm_usb` and `nutdrv_atcl_usb` drivers for now
     [#1763, #1764, #1768, #2580]
 - All drivers should now support the optional `sdcommands` setting with
   a site-local list of instant commands to handle `upsdrv_shutdown()`,
   which may be useful in cases when the driver's built-in commands
   (or their order) do not meet the goals of particular NUT deployment.
   This can also help with shutdown endgame testing, using a mock command like
   starting the beeper (where supported) to verify that the UPS communications
   happen as expected, without compromising the load connected to the UPS.
   Also defined `EF_EXIT_SUCCESS` and `EF_EXIT_FAILURE` in `include/common.h`
   to avoid magic numbers in code like `set_exit_flag(-2)`, and revised whether
   it is getting set at all in "killpower" vs. other cases, based on new
   `handling_upsdrv_shutdown` internal flag.
	NOTE: during this overhaul, many older drivers got their first ever supported
	INSTCMD such as `shutdown.return`, `shutdown.stayoff` or `load.off`. Default
	logic that was previously the content of `upsdrv_shutdown()` methods was often
	relocated into new `shutdown.default` INSTCMD definitions. [#2670]
 - Common code:
   * `upscli_splitname()` should now recognize `upsname:port` typos (missing
     the `@hostname` part) and error out gracefully.
   * Introduced a `NUT_DEBUG_SYSLOG` environment variable to tweak activation
     of syslog message emission (and related detachment of `stderr` when
     backgrounding), primarily useful for NIT and perhaps systemd. Most
     methods relied on logging bits being set, so this change aims to be
     minimally invasive to impact setting of those bits (or not) in the
     first place. [#2394]
   * `root`-owned daemons now use not the hard-coded `PIDPATH` value set
     by the `configure` script during build, but can override it with a
     `NUT_PIDPATH` environment variable in certain use-cases (such as
     tests). [#2407]
   * Allow drivers to set `STATEPATH` via `ups.conf` to match `upsd`
     custom configuration ability; the data server would prefer the value
     from `ups.conf` over the one in `upsd.conf`, if both are present.
     Note that `NUT_STATEPATH` environment variable trumps both. [issue #694]
   * Introduced a check for daemons working with PID files to double-check
     that if they can resolve the program name of a running process with
     this identifier, that such name matches the current program (avoid
     failures to start NUT daemons if PID files are on persistent storage,
     and some unrelated program got that PID after a reboot).  This might
     introduce regressions for heavily customized NUT builds (e.g. those
     embedded in NAS or similar devices) where binary file names differ
     significantly from a `progname` string defined in the respective NUT
     source file, so a boolean `NUT_IGNORE_CHECKPROCNAME` environment
     variable support was added to optionally disable this verification.
     Also the NUT daemons should request to double-check against their
     run-time process name (if it can be detected). [issue #2463]
   * Introduced `m4` macros to check during `configure` phase for the
     platform, and a `nut_bool.h` header with `nut_bool_t` type to use
     during build, to avoid the numerous definitions of Boolean types
     and values (or macros) in the NUT codebase. [issue #1176, issue #31]
   * Custom `distcheck-something` targets did not inherit `DISTCHECK_FLAGS`
     properly. [#2541]
   * Added `status_get()` in NUT driver state API, to check if a status
     token string had been set recently, and to avoid duplicate settings;
     fixed `status_set()` for multi-token arguments. [PR #2565, issue #2708]
   * Local socket/pipe protocol introduced a `LOGOUT` command for cleaner
     disconnection handling. [#2572]
   * Codebase adapted to the liking of `clang-18` and newer revisions of
     `gcc-13`+ whose static analyzers on NUT CI farm complained about some
     imperfections after adding newer OS revisions to the population of
     build agents. [#2585, #2588]
   * New checks in `clang-19` brought new findings about mismatched formatting
     strings and `int`-ish parameters of respective methods.
     Overall, had to change formatting strings in some cases, variable types
     in others (e.g. flags or notification types do not make sense as signed)
     and added casting in a few places that remained, because:
     - `%x` style formatting requires an `unsigned int` variable
     - Numeric literals and macros are `int` by default
     - Results of math with unsigned types like `uint16_t`, done in some
       cases, are up-scaled into `int` by default
     - `char`'s, `unsigned` or not, seem to be also up-scaled into `int`
 - Updated `docs/nut-names.txt` with items defined by 42ITy NUT fork. [#2339]
 - Various recipe, documentation and source files were revised to address
   respective warnings issued by the new generations of analysis tools.
   [#823, #2437, nut-website issue #52]
 - Fixed `configure` script to use default (target-specific) values of
   `CFLAGS`, `LIBS` etc. when probing relevant settings for each third-party
   dependency; as a consequence, on systems that support building for many
   targets, we check relevant build-ability for that target and not for the
   building system itself. [issue #2673, PR #2675]
 - Fixed dynamic linking of Mozilla NSS on systems like Solaris/illumos,
   where the shared objects are not packaged into the common RPATH.
   [issue #2674, PR #2675]
 - Added `scripts/valgrind` with a helper script and suppression file to
   ignore common third-party problems. [#2511]
 - Fixed `configure --with-valgrind=PATH` vs. detection of its usability;
   fixed some portability issues with detection of usability per se, tried
   `--with-valgrind=auto` the default to auto-detect and use the feature
   (in tests) wherever possible, but too many NUT CI farm agents disagreed;
   so for now the default is `no`. [#2823]
 - When drivers dump collected data (during troubleshooting), flush `stdout`
   buffer immediately for sane logging (especially on Windows). [PR #2699]
 - Revised `nut.exe` (the NUT for Windows wrapper for all-in-one service)
   to be more helpful with command-line use (report that it failed to start
   as a service, have a help message, pass debug verbosity to launched NUT
   programs...) and add a man page for it. [issue #2432, PR #2446]
 - The `scripts/Windows/build-mingw-nut.sh` helper script was extended to
   use `nut_build_${ARCH}` and `nut_install_${ARCH}` directories by default,
   with the older `nut_build` and `nut_install` short names becoming just a
   symbolic link to the latest executed build: this should help compare the
   differences of 32/64-bit builds, without them stepping on each other's toes.
 - NUT binding for Python and the `NUT-Monitor` Python UI client updates:
   * The `PyNUTClient` module should no longer rely on presence of a `telnetlib`
     module in the build or execution environment (deprecated in Python 3.11,
     removed since Python 3.13). [issue #2183, PR #2792]
   * The PyPI distribution of the `PyNUTClient` module tarball should now use a
     lower-cased file name (and immediate versioned directory name inside) to
     match the requirements of https://peps.python.org/pep-0625/.
     The Python module name (and its directory) should remain camel-cased. [#2773]
   * Added man page for the `NUT-Monitor` Python UI client.
   * The `NUT-Monitor` Python UI client itself was revised to report the
     `PACKAGE_VERSION` and `NUT_WEBSITE_BASE` strings in the "About" dialog
     contents; localization support for the dialog and some other resources
     was revised to work in Py3Qt5 variant of the script. [#722]
 - Documentation recipe updates:
   * Enabled installation of built single-file PDF and HTML (including man
     page renditions) under the configured `docdir`. It seems that previously
     they were only built (if requested) but not installed via `make`, unlike
     the common man pages which are delivered automatically. [#2445]
	NOTE: The `html-chunked` documents are currently still not installed.
   * Added support to `./configure --with-doc=man=dist-auto` to use the
     distributed manual page files if present; only fall back to (re-)building
     them if we can. [#2473]
   * Added a `make distcheck-light-man` recipe to require verification that
     the manual page files can be built using the prepared "tarball" archive.
     [#2473]
   * Revised the documentation building recipes, with the goal to avoid
     building the `ChangeLog` products and their intermediate files more
     than once (but still react to `git` metadata changes during development),
     and to sanity-check the resulting final document (currently only for
     `html-single` mode).
     As part of this, the `CHANGELOG_REQUIRE_GROUP_BY_DATE_AUTHOR` setting was
     added (for `make` calls and used by `tools/gitlog2changelog.py.in`
     script), and it defaults to `true` allowing for better ordered documents
     at the cost of some memory during document generation. [#2510]
   * Updated man page generation with `configure` script options to specify
     that manual section codes on the target platform differ from (Linux-based)
     defaults hard-coded into page sources; this should allow to simplify NUT
     packaging recipe maintenance in those diverse distributions (no more need
     to update patches for changed or added documentation sources).
   * Lines in first section of NUT configuration report (which can optionally
     remain as `config.nut_report_feature.log` and be installed into shared
     documentation of a NUT package) are now better grouped as miscellaneous
     features and detection results, then drivers and programs/tools. [#2676]
 - Added a `common/Makefile.am` build product for a new internal library
   `libcommonstr.la` which allows a smaller selection of helper methods
   for tools like `nut-scanner` which do not need the full `libcommon.la`
   nor `libcommonclient.la`. [#2478, #2491]
 - Added a `drivers/Makefile.am` build product for a new internal library
   `libserial-nutscan.la` to simplify `tools/nut-scanner/Makefile.am` recipes.
   [#2490]
 - Build of `snmp-ups` and `netxml-ups` drivers now explicitly brings linker
   dependency on chosen SSL libraries. [#2479]
 - Introduced `configure --with-modbus+usb` option to require an USB-capable
   libmodbus, and defaulted a couple of specific situations as if this was
   required (implicitly): `configure --with-modbus --with-usb` and
   either `--with-drivers=*apc_modbus*` (actually implies `--with-modbus`)
   or `--with-modbus-includes=... --with-modbus-libs=...`
   as a way to avoid surprises with custom NUT builds aiming to have an
   USB-capable `apc_modbus` driver (currently this requires a custom-built
   libmodbus). Also fixed (re-)detection of libmodbus RTU USB support with
   static libmodbus builds. [#2666]
 - Drivers built with libmodbus (`phoenixcontact_modbus`, `generic_modbus`,
   `huawei-ups2000`, `socomec_jbus`, `adelsystem_cbi`, `apc_modbus`) should
   now report whether the library is linked dynamically or statically -- this
   can help in troubleshooting (especially of `apc_modbus` which may be using
   a custom build of the library not delivered by the operating system). [#2897]
 - Brought keyword dictionaries of `nutconf` and `augeas` NUT configuration
   file parsers up to date; restored automated checks for `augeas` lenses.
   [issue #657, issue #2294]
	NOTE: Some known issues remain with augeas lens definitions, so currently
	   they should be able to parse common simple use-cases but not certain types
	   of more complex configurations (e.g. some line patterns that involve too
	   many double-quote characters) which are valid for NUT proper. [#657]
 - Cross-builds using only a host implementation of `pkg-config` program
   should now ignore host `*.pc` files and avoid confusion.
 - NUT CI farm build recipes, documentation and some `m4`/`configure.ac`
   sources updated to handle a much larger build scope on MacOS. Also
   migrated the builders to Apple Silicon from x86 (deprecated by CircleCI).
   Disabled `HOMEBREW_NO_AUTO_UPDATE` to gain 40 min per build at cost of
   slightly older environment. [#2502, #1579]
 - Introduced a simple experiment to expose NUT client readings as filesystem
   objects via FUSE, in `scripts/fuse/execfuse-nut` now. [#2591]
 - Introduced `make install-as-root` to create directories not directly
   populated by `make install` and NUT build artifacts, apply permissions
   and (on some platforms) restart services involved with NUT. [#1298]
