 =================
 
-The primary purpose of this release is a set of enhancements to
-support virtualenvwrapper.project_, a new extension to manage project
-work directories with templates.  2.1 also includes several smaller
-changes and bug fixes.
-
-- Add support for ksh.  Thanks to Doug Latornell for doing the
-  research on what needed to be changed.
-- Test import of virtualenvwrapper.hook_loader on startup and report
-  the error in a way that should help the user figure out how to fix
-  it (issue #33).
-- Update mkvirtualenv documentation to include the
-  fact that a new environment is activated immediately after it is
-  created (issue #30).
-- Added hooks around cpvirtualenv.
-- Made deactivation more robust, especially under ksh.
-- Use Python's ``tempfile`` module for creating temporary filenames
-  safely and portably.
-- Fix a problem with ``virtualenvwrapper_show_workon_options`` that
-  caused it to show ``*`` as the name of a virtualenv when no
-  environments had yet been created.
-- Change the hook loader so it can be told to run only a set of
-  named hooks.
-- Add support for listing the available hooks, to be used in help
-  output of commands like virtualenvwrapper.project's mkproject.
-- Fix mkvirtualenv -h option behavior.
-- Change logging so the $WORKON_HOME/hook.log file rotates after
-  10KiB.
