Hello Matthias,
I just saw that you already uploaded the squid tarball to the source server a few days ago. Hence I assume you have a patch for the update somewhere.
I was about to update the package, but if you did that already, I would rather like to just pull the patch. Could not find anything in your repository.
Could you please send the patch if it is ready? Are you otherwise still debugging some issues with the version update?
Best, -Michael
