BioCASe now runs on Python 3

A new version of BioCASe has been published that runs on Python 3. For this, the software underwent a thorough overhaul, which included a lot of code cleaning and bug fixing.

The Python 3 version is up to 50% faster due to code removal/re-implementation and Python optimizations (tested on MySQL and SQL Server databases). External dependencies have been reduced, which makes installation way easier. Last but not least, BioCASe now deals better with unexpected control characters in the sources databases, which caused a lot of pain in the previous versions.
