I thought the whole point of this Debian stuff was to keep everything up to date and modern with upstream management of updates? So FreePBX Users would always be able to roll with “stable”?
The debian team released RC1 in July, When a company platforms itself on a product it seems reasonable that all of this should have been in progress since Alpha 1 (December) allowing these things to be worked through. Especially since 13 is an LTS. In any case the time to discover and start working on an issue for the platform that can always be up to date was 6 months ago and not 2 days post stable release.
