Joomla 1.0.13 and 1.5 RC 1:

Please note that CB 1.0.2 is not compatible with Joomla 1.0.13 and 1.5 RC 1, but CB 1.1 is compatible with all versions of Joomla (except beta versions).

You need to update CB to CB 1.1 first, before updating Joomla to Joomla 1.0.13.

Before updating to Joomla 1.0.13, you need to be aware of the problems and solutions, as discussed in this forum.

Well, if you already updated Joomla to 1.0.13, simply update CB to CB 1.1.

One interesting side-effect of CB 1.1 is that it adapts the database storage to the host CMS, meaning you can also downgrade from Joomla 1.0.13 to Joomla 1.0.12 or any previous version, if needed while keeping the CMS database compatible.

Mambo 4.6.2:

Please note that CB 1.1 is compatible with latest Mambo 4.5.2 to 4.6.2 natively, without any changes. CB 1.0.2 was compatible with Mambo 4.5.0 - 4.5.5 (and with 4.6.2, with a simple change in the login module).
