OK, I noticed new changes out on Marriott.com and I resisted referring to them as Software Downgrades in this threads title. Time will tell.

MR number is preloaded in Marriott Rewards Number field with asterisks and last 3 numbers showing (when not signed in) - I like it. Once signed in the whole MR number is shown.

New inline drop down calendars that work. The old separate windowed calendars stopped working a couple weeks back. Bad thing about new calendars is if you want to book a few months down the road, then there is no shortcut to select the month. However, you can put a date in the date field for the month you want and the floating inline calendar will show that month. Another nice feature is that if the check-out date is empty or earlier than the check-in date then it will automatically load it with the day after the check-in date. If the check-out date is later than the check-in date then it will retain check-out date you had entered even if the check-in date is changed.

As best I can tell at quick glance that is all the changes I noticed. If others notice changes, please share them with us. As most of you are aware I stay pretty alert with regard to postings here on the MR forum and did not see a thread discussing this, so if there has been one, my apologies and Mod is free to merge and/or close this thread.
