The "official" list is of course the CoreUpdates folder. See, for 
instance #5021 and #5022. If in doubt, go to CoreUpdates and do `grep * 
-e 'MovableMorph'` and `grep * -e 'WidgetMorph'`, etc.

I wouldn't say "blindly". If your packages work correctly at a certain 
Cuis update #, then you can load the following updates. One of the good 
properties of the numbered updates is that you can review the code, and 
evaluate their effect on your own code. This is actually the _only_ way 
for you to give guarantees on the ongoing state of your packages that 
are not in the Cuis-Smalltalk organization. (I did update _all_ the 
packages in the Cuis-Smalltalk organization).

Additionally, you can check the commit history at GitHub. The commint 
message of 
https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/commit/b7b8e1f75f8d16775b0ec9e2424e0ea6afd735a9 
tried to be descriptive: "Morphs class renames. Update copyright to 
2022. Bump Cuis version to 6.0". Checking the changes made to packages 
in the Cuis repo in that commit should be helpful.

Also, a lot of this was discussed in _great_ detail in this mail list, 
to find names that make sense to the Cuis community. See 
https://lists.cuis.st/mailman/archives/cuis-dev/2021-December/004740.html and 
https://lists.cuis.st/mailman/archives/cuis-dev/2021-December/004745.html .

Hope this helps.
Cheers,
