We have an application which currently uses PRISM 5 which we migrated from PRISM 4 using the upgrade notes: https://msdn.microsoft.com/en-us/library/ff921144(v=pandp.40).aspx
Are there similar upgrade notes from PRISM 5 to 6?
I am interested in the breaking changes so that we plan the upgrade accordingly.
UPDATE: https://github.com/PrismLibrary/Prism/wiki/Release-Notes---6.0.0
Prism is now maintained on github https://github.com/PrismLibrary/Prism/ by the community.
There are a wiki section where you can find some release notes with the breaking changes.
