Is there a document that says what has changed between BCT Versions?

Where you can find the BCT Change Log

The changelog contains a list for each BCT Product. There you see which PR/ER were implemented in which version.

You will find it after the installation under: D:\BCT v24R1\inspector\changelogs
Or on our website:
