Release Notes 2.5.3
Confluence 2.5.3 is a maintenance release that resolves issues users may have encountered using Confluence 2.5 or earlier.
2.5.3 is a free upgrade for all customers who purchased their Confluence license after May 30th 2006.
Who should upgrade?
Confluence 2.5.3 is a bugfix release which resolves some significant issues in Confluence 2.5. Customers running older versions of Confluence should review the list of resolved issues below, and upgrade if this release fixes any problems with their current Confluence installation.
In particular, 2.5.3 fixes a problem which could cause indexing to fail when extracting text from unprintable encrypted PDF files.
Customers running releases older than 2.5 and wishing to upgrade should upgrade directly to 2.5.3.
Shared Mode Removed
This release removes the 'Shared Mode' setting from General Configuration. If you have shared mode enabled you should disable it before upgrading.
Upgrading Confluence should be pretty easy. If you are upgrading from another Confluence 2.2.x or a later version, you can find instructions here.
We strongly recommend that you backup your
confluence.home directory and database before upgrading!
Upgrading from Confluence 2.1 and earlier
Users upgrading directly from 2.1 or earlier should also read the 2.2 Release Notes for caveats regarding the 2.1 -> 2.2 upgrade.
