@donho ,
Thanks for this.
I can confirm that
Auto-completion performance is back to where it should be, rather than the super-slow from v8.0. Great!
“Open” looks much better than “Save” in the Open dialog. ;-) Thanks!
The fix for
#9939, which just missed the deadline for v8.0, is correctly working in v8.1 (I can get the extension appended with Enter, Alt+S, or hitting Save button).
So the fixes that I was most looking forward to after v8.0 are all working in v8.1-RC2.
Thanks for all your effort (@donho and the rest of the v8.1 contributors)!
