I reported this morning at the Search Engine Roundtable on Small But Important New Google AdWords Features & Fixes. eWhisper at WebmasterWorld tracked the small, sometimes unnoticed, changes within Google AdWords and put together a list. Here is that list.
+ Local time zone added to MCC reports.
+ Bug fixed where the 'account' box didn't show on sub mcc reports.
+ Add your GAP business to Google Local (although, not sure why this wasn't attached to base so the pin was unnecessary)
+ HTTPs errors fixed on internal help pages (note, the only place I can tell the error now occurs is on the help home page).
+ Possible negative keywords under the AdWords keyword tool.
+ Ability to add keywords to an AdGroup when accessing the keyword tool from the tools menu.
+ 'add custom text' under the site spidering section of the keyword tool.
