For those who may not be aware Asterisk 14 transitioned from bug fix mode to security-fix-only mode a few weeks ago (Sept 26th). For those of you that are still on this release, it’s a good time to consider building an upgrade plan for moving to 15.x.x. I sincerely apologize for the late notification. Somehow, this was overlooked in the push to get 15.0.0
You can read more about this process and the relevant dates on the wiki at https://wiki.asterisk.org/wiki/display/AST/Asterisk+Versions
Best wishes, and sorry again about the confusion on this.
