Release Notes

This release features many fixes and improvements, but also a few backward incompatible changes:

removed GaudiGSL package (in preparation for the licensing under Apache 2) (gaudi/Gaudi!879)
change of IEventProcessor interface (gaudi/Gaudi!877)
change (const correctness) of custom containers interfaces (gaudi/Gaudi!896)
