Updates
This page details the expected times that each major release of Moodle (eg 1.9, 2.0) will continue to receive core updates in the form of new versions (eg 1.9.x, 2.0.x) to fix bugs found in that version (especially security-related fixes).
Note that you can continue using old versions of Moodle as long as you like, but that we highly recommend you upgrade to a version that is still receiving bug fixes, and preferably the very latest release.
Future dates reflect current expectations, they may be extended if necessary but please don't rely on it.
