ANN: Pyrex 0.9.8
by greg 15 May '08

15 May '08

Pyrex 0.9.8 is now available: http://www.cosc.canterbury.ac.nz/greg.ewing/python/Pyrex/ This version has a number of new features: * In-place operators (+= etc.) are now supported. * The Pyrex compiler now has built-in facilities for automatically tracking down and compiling all the modules a given module depends on, and for only compiling modules whose source has changed. * Some restrictions on nogil functions have been relaxed. In particular, it's now possible to declare a C method as nogil. * A feature has been added that makes it easier to manage circular imports between .pxd files. It's now possible to declare two extension types in different .pxd files that refer to each other. What is Pyrex? -------------- Pyrex is a language for writing Python extension modules. It lets you freely mix operations on Python and C data, with all Python reference counting and error checking handled automatically.

[ANN] Release 0.70.0 of Task Coach
by Frank Niessink 12 May '08

12 May '08

Hi, I'm happy to announce release 0.69.2 of Task Coach. This release contains small feature enhancements, more translations and several bug fixes. Task Coach is now distributed under the GPLv3+. Bugs fixed: * Allow for editing seconds in effort editor. * The combobox in the effort detail editor always picked the first task when multiple tasks had the same subject, effectively prohibiting the user to move an effort record to another task with the same subject. * Reset invalid input in the priority field of the task editor to 0 instead of to the minimum priority (a large negative value). * "View->Filter->Reset all filters" now also unchecks all categories. * Task Coach now is packaged as a proper Debian package, thanks to Stani Michiels. The Debian package installs a menu item for Task Coach in the Applications/Office menu. Features added: * Paths to file attachments may be relative. * Monthly and yearly recurrence of tasks. * Added and reorganized keyboard short cuts. * Start tracking effort for any active task using the system tray icon right-click menu. * Added a largely complete Ukranian translation thanks to Vitovt and incomplete Finnish, Greek, Persian and Thai translations. Feature changed: * Slightly higher preference window so all icons fit and no scrolling is needed. Dependencies changed: * Task Coach now uses Subversion for version control. See http://sourceforge.net/svn/?group_id=130831. This only affects you if you want to develop or use Task Coach source code. * Task Coach is now distributed under the GNU General Public License version 3 or (at your option) any later version. This only affects you if you want to distribute changed versions of Task Coach or want to include source code from Task Coach in other software. 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://www.taskcoach.org In addition to the source distribution, packaged distributions are available for Windows XP/Vista, Mac OS X, and Linux (Debian and RPM format). 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
