These are not Release Notes! This is an informal list of changes which are considered important or interesting to the users of FreeBSD. As such, they may contain incomplete or wrong information. If you are a developer, please keep this page updated!

These notes have not been updated in some time! This page was largely updated during the lead-up to FreeBSD 11, and many of the items have received further updates after those noted below.

The intent is for this page to collect major, user-visible changes to FreeBSD while in the development cycle for FreeBSD 11, no matter if the changes are eventually MFC-ed to earlier versions.
