Changes in magit 0.7:

* Tagging, on 't' and 'T'.

* Stashing, on 'z'.

* Wazzup, on 'w'.  Wazzup gives you an overview over how other
  branches relate to the current one.

* There is more control over pushing.  'P' now takes a prefix argument
  and pushing a branch without a default remote will ask for one.

* Logs have changed a bit: 'l' shows the traditional brief log, and
  'L' shows a more verbose log.  Use the prefix arg to specify the
  range of the log.

* M-x magit-status doesn't prompt anymore for a directory when invoked
  from within a Git repository.  Use C-u to force a prompt.

* The digit keys '1', '2', '3', and '4' now show sections on the
  respective level and hide everything below.  With Meta, they work on
  all sections; without, they work only on sections that are a parent
  or child of the current section.

* Magit works better with oldish Gits that don't understand "--graph"
  for example.

Changes in magit 0.6:

Almost everything has changed.  Please read the manual again.  Some
highlights:

* Magit now works with Git 1.6.0.  (John Wiegley)

* Support for interactive rewriting.

* Sections can be shown and hidden.

* Staging, unstaging, applying, reverting and discarding changes can
  now be done line-by-line, not only hunk-by-hunk.
