<h1>Supported Versions</h1>

<p>

Each release branch of PHP is fully supported for two years from its initial

stable release. During this period, bugs and security issues that have been

reported are fixed and are released in regular point releases.

</p>

<p>

After this two year period of active support, each branch is then supported

for two additional years for critical security issues only. Releases during

this period are made on an as-needed basis: there may be multiple point

releases, or none, depending on the number of reports.

</p>

<p>

Once the four years of support are completed, the branch reaches its end of

life and is no longer supported. <a href="/eol.php">A table of end of life

branches is available.</a>

</p>
