What does this mean for you?
It means that if you are using Asterisk 1.2, you should start considering a plan for upgrading your servers to Asterisk 1.4. Asterisk 1.2 is not going away anytime soon. You can expect that Asterisk 1.2 will be maintained for security issues until Asterisk 1.6 is released, and most likely longer than that. However, some time after Asterisk 1.6 is available, Asterisk 1.2 will become officially deprecated and no longer supported with fixes of any kind from the core Asterisk development community.
We ask that you please work with us to help ensure that Asterisk 1.4 is a stable platform for your telephony needs. If you find a bug, please work with the development community to help get it resolved. After all, this is a community project! Remember, before creating a bug report on http://bugs.digium.com/, check to make sure there isn't already a report for the same problem.
The development team is very dedicated to fixing bugs and maintaining feature frozen releases. Our maintenance of the Asterisk 1.2 series for over a year and a half is a testament to this. We are going to work
very hard over the next couple of months to help ensure that Asterisk 1.4 is the best Asterisk release series yet.
Thank you for your patience and understanding as we move forward with Asterisk development, and as always, thank you very much for your support!
The Asterisk.org Development Team
