After updating Joomla to version 3.2.3 (using MySQL database), the Extensions > Extension Manager > Database > [Fix] shows "Warning: Database is not up to date!"
1 Database Problem Found:
Database schema version (3.2.3-2014-02-20) does not match CMS version (3.2.3).
What is the cause
This is a view issue, not a database issue. When you get the error above, just do not worry. The view itself will be corrected in next release
How to fix
Apparently this check will be fixed in the next Joomla version: https://github.com/joomla/joomla-cms/commit/b382d19b2ae5dcb320c56628b237545bbb31b2cd
