changelog : more detail?

[Jason]

I logged in to find 2 change/revisions since I last looked. Nothing security related so I don't need to upgrade but looking at the changelog brings up a question:

Version 6.3.16:
F Added the ability to remove specific days/columns from the TOC Mode calendar display.
B Fixed a HTML formatting issue with the Normal Mode calendar table header.
Version 6.3.15:
C Updated output for improved validation.
C Updated the licensing system for better server compatibility.

Is there any chance there's a dopcument that gives better details than the changelog? In looking at those 2 latest entries it looks like I'd be taking a bit of a chance on whether or not the upgrade would casue html/browser rendering issues that I'd need to fix after upgrading.

I need to know how much time I'll be spending on a task before I get into it if at all possible and this information would help a great deal.

"HTML formatting issue" and "Updated output for improved validation" hint that HTML has been revised but give no real clue as to what's been done.

If there's a place where this is documented could you help me to it? If it's not documented, care to share?

thanks

C Updated the licensing system for better server compatibility.
Internal code changes.

C Updated output for improved validation.
Through suggestions in the forum, several places in the HTML output added quote marks around some elements. Doesn't affect the look, but helps with certain validation.

B Fixed a HTML formatting issue with the Normal Mode calendar table header.
When adding the quote marks in the previous release, one was misplaced outside of a close tag. Again, visually there was no difference, but for validation, it was moved.F Added the ability to remove specific days/columns from the TOC Mode calendar display.
Feature request added and documented in the Command-line section of the instructions.
