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.
