You can also get the absolute latest cutting edge (and thus potentially untested and unstable) version of b2evo from the CVS server on SourceForge.
There is absolutely no guarantee about the state of the CVS version. Some days it will be the most stable version you could find, and some days it might just be broken and waiting for a fix...
This version is only recommended for contributing developers.

Detailed system requirements »
The regular upgrade procedure works for upgrading from any version of b2evolution to any more recent version. b2evolution's installer/upgrader will automatically detect which older version you are upgrading from.
However, starting with version 1.8.2, any minor upgrade (3rd digit upgrade as in 1.8.1 to 1.8.2) will not require any database upgrade and you may be able to upgrade just by replacing a few files. See quick upgrade patches below.
For example: upgrading from 1.9.0 to 1.9.2 only requires to replace the application files (attention: make sure to properly update your /conf files!). No database upgrade necessary. This means you can also downgrade back to 1.9.1 or 1.9.0 as easily. You could not downgrade to 1.8.x without restoring a database backup, though.
If you are already running a 2.4.x release, no database upgrade is necessary and you can upgrade just by replacing a few files. Just make sure you properly update your /conf files.

If you are an advanced linux user/admin/coder, you may want diff patches instead. You will find them at diffs.b2evolution.net .
If you want to migrate from b2/cafelog or Movable Type, just follow the instructions in the latest release.
If you want to migrate from Geeklog or Manywhere Miniblog, first import into b2evolution 0.9.2, then upgrade to the latest version.
If you want to migrate from any other blog tool, we recommend you try to export the contents to the Movable Type export format and then use the MT importer in the latest release.
