if you hover over a branc now you can see the commit history on that branch. it will display the hash author date title and message associated with that commit. very good very nice!!!!
ever messed up a feature and its not working, and you just dont want to work on that shit anymore, well thats how i use stash. all the changes into the stash so that i can fix it in the future (will never get worked on in the future)
when renaming a commit the program was unable to Push because the local branch had diverged from the remote branch. now there is a divergance handler that asks you if you want to force push anyway, which is very nice!
