Periodically, we will announce a Long Term Support (LTS) version. LTS versions are supported for a duration of 3 years from the time of release with security and critical bug fixes.
Opting-in to an LTS version can be done by modifying the Composer requirement for Zend Framework:
$ composer require "zendframework/zendframework:~2.4.0"
The above will modify your composer.json to pin to the semantic version 2.4.0, ensuring you only get updates in the 2.4 series. If you want to pin to a different LTS version, specify the X.Y.0 version for it instead.

| Zend Framework 2.4 | 2015-03-31 | 2018-03-31 |
