Quote from release note:

Note that according to our release schedule, PHP 5.5.38 is the last release
of the PHP 5.5 branch. There may be additional release if we discover
important security issues that warrant it, otherwise this release will be
the final one in the PHP 5.5 branch. If your PHP installation is based on
PHP 5.5, it may be a good time to start making the plans for the upgrade to
PHP 5.6 or PHP 7.0.
