感觉有点像Ubuntu的发布周期，半年发布一个版本，不错

Asterisk Versions
There are multiple maintained feature frozen releases of Asterisk. Once a release series is made available, it is maintained for some period of time. During this initial maintenance period, releases include changes to fix bugs that have been reported. At some point, the release series will be deprecated and only maintained with fixes for security issues. Finally, the release will reach an End of Life, where it will no longer receive changes of any kind.

The type of release defines how long it will be maintained. A Long Term Support (LTS) release will be fully maintained for 4 years, with one additional year for security fixes. Standard releases are maintained for a shorter period of time, which will be at least one year of full maintenance and an additional year of security fixes.

The following table shows the release time lines for all releases of Asterisk that have not yet reached End of Life.

Release Series                Release Type        Release Date        Security Fix Only        EOL
1.2.X                        2005-11-21        2007-08-07        2010-11-21
1.4.X        LTS                2006-12-23        2010-12-23        2011-12-23
1.6.0.X        Standard        2008-10-01        2010-04-01        2010-10-01
1.6.1.X        Standard        2009-04-27        2010-04-27        2011-04-27
1.6.2.X        Standard        2009-12-18        2010-12-18        2011-12-28
1.8.X        LTS        TBD (Goal: Q2 2010)        TBD + 4 years        TDB + 5 years
New releases of Asterisk will be made roughly every six months. Releases marked as LTS releases will be much less frequent. Within a given release series that is fully maintained, bug fix updates are provided roughly every 4 weeks. For a release series that is receiving only security fixes, updates are made on an as needed basis.

If you're not sure which one to use, choose either the latest release for the most up to date features, or the latest LTS release for a platform that may have less features, but will usually be around longer.

这个要看具体的版本都修订了什么内容了，可以看changelog。
