List of actual BUG FIXES in Cubase 11?

Are there any official release notes available outside of the advertising pages on the Steinberg site? Preferably something that details actual bug fixes?

If history is any indicator, Steinberg has added a bunch of new features in Cubase 11 but fixed none of the existing issues from 10/10.5…


No, there is not.
They never have such a list for new major versions. Only for maintenance updates.
