C-h n (
view-emacs-news) for all the details. Some highlights:
M-x list-packages to browse and install packages, which are enabled by default. If you've installed a number of packages but you don't want them to all load at startup, customize
package-load-list. Not that many packages yet, but I'm sure people will add more.
Emacs themes and user-interface changes
M-x customize-themes lets you choose color themes or create your own. There have also been a number of user-interface cleanups (scrollbars on the right, smoother antialiasing, that sort of stuff), but nothing radical.
Big one for international support.
x-select-enabled-clipboard is now true by default, which means Emacs newbies in Linux won't get confused by an inability to copy and paste between applications.
With the increasing popularity of distributed version control systems such as bzr, we now have a way to pull updates using
M-x vc-update (also known as
M-x vc-pull). There's also a
M-x vc-merge command. Looking forward to git support for both of these.
There is a
create-animated-image function. Interesting.
