Thank you for your feedback and sorry for the caused inconvenience. Unfortunately, I cannot tell you the exact date when we will release the internal build with the fix for these good-code-reds.
It should be either this or next week, but since unexpected things could happen, I cannot promise you anything.
As for the shortcut for the block comment command - currently we do not plan to change this shortcut since changing it could potentially break other key combinations.
