[ANN] Release 0.52 of Task Coach

[Frank Niessink]

Hi all,

I'm pleased to announce release 0.52 of Task Coach. New in this release:

Bugs fixed:
* For completed tasks, the number of days left for a task is now the
   number of days between the completion date and the due date. This
   prevents that the number of days left of completed tasks keeps
   decreasing, i.e. becoming more negative. For uncompleted tasks, the
   number of days left is still the number of days between today and the
   due date, of course. Patch provided by Maciej Malycha.
* Put taskocachlib package first on the Python search path to prevent
   name conflict with the config module on Gentoo Linux.
* Mention blue icon in the help on task colors.
* Don't allow empty categories.

Features added:
* Tasks can be dragged and dropped.
* Tasks can have an hourly fee and/or a fixed fee. Revenue is calculated
   based on effort spent.
* First tiny steps towards a user manual, see 'Help' -> 'Help contents'.
* Whether the main window hides itself when iconized is now adjustable
   behavior. See 'Edit' -> 'Preferences'.

Feature changed:
* Backups are created just before saving, instead of when loading a .tsk
   file. Patch provided by Maciej Malycha.

Feature removed:
* Files in the old comma-separated format can no longer be read by Task
   Coach.


What is Task Coach?

Task Coach is a simple task manager that allows for hierarchical
tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is
developed using Python and wxPython. You can download Task Coach from:

http://taskcoach.niessink.com
https://sourceforge.net/projects/taskcoach/

A binary installer is available for Windows XP, in addition to the
source distribution.

Note that Task Coach is alpha software, meaning that it is wise to back
up your task file regularly, and especially when upgrading to a new release.

Cheers, Frank
