<p>There are multiple supported feature frozen releases of Asterisk. Once a release series is made available, it is supported for some period of time. During this initial support 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.</p>
<p>The type of release defines how long it will be supported. A Long Term Support (LTS) release will be fully supported for 4 years, with one additional year of maintenance for security fixes. Standard releases are supported for a shorter period of time, which will be at least one year of full support and an additional year of maintenance for security fixes.</p>
<p>The following table shows the release time lines for all releases of Asterisk that have not yet reached End of Life. If you do not see a release series listed here, then it has already reached EOL.</p>

<p>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 supported, bug fix updates are provided roughly every 4 weeks. For a release series that is receiving only maintenance for security fixes, updates are made on an as needed basis.</p>
<p>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.</p>
