A small patch release (3.0.3) is now available for Catalina. It applies to both Win32 and Linux distributions, and must be installed over an existing Catalina 3.0 installation.
This patch release contains significantly enhanced Code::Blocks integration, as well as a few minor bug fiexes and enhancements.
This is a cumulative patch which also contains all the fixes in the previous patch releases.
