Where to find under the Hood specs of RB6?

Hy,

where can i find under the Hood specs of rb6?

Things like which (hopefully new) keylock algo, Audio processing (a look in the source Code Shows that the Juce engine is still used, but which Revision and which Plugins), is there a better limiter integrated now (if yes what Kind of limiter/how does it work)?

btw. the (Long time) well known bug with the rekording Levels is still not fixed. 

thx in Advance for the Infos!
