This file lists the supported versions of roundcube and databases by the plugin. Other versions than those listed may work, but have not been tested.
The latest patchlevel of roundcube is supported for all branches of roundcube still supported by the roundcube project.
These currently are:
- Version 1.4
- Version 1.5
I recommend using the latest stable roundcube version, which the plugin is most tested with.
RoundCube CalDAV may work with older versions of roundcube, but is not supported.
