Yesterday, Google made two quick announcements about bug fixes with Google Webmaster Tools.
The first item was that the URL Removal tool was not working. A Google Webmasters Help thread has confirmation from Susan Moskwa, a Googler, that this was indeed the case. Susan even tweeted that her "inbox is full of email about URL removal requests," implying there was an issue. Susan confirmed that the issue is now resolved and removal requests should now be working.
The second item is that in the new Google Webmaster Tools UI, Google had to disable the option to subscribe to notifications. Google has updated us via Google Webmasters Help that they have re-enabled this feature and you can now subscribe to notifications in the new user interface.
