OpenProj

For many years, the only decent free end-user app was GIMP, and the history of open source on the desktop has been one of gradually filling major holes - office suite, browser, email etc. - to bring it up to the level of proprietary offerings.

Happily, things have moved on, and it's now possible to use free software for practically any desktop activity. One major lack has been project planning, traditionally the (expensive) realm of Microsoft Project. No longer it seems. With the launch of OpenProj, the open source world now has a free alternative, for a variety of platforms.

It's still too early to say how capable the program is, but it's certainly a welcome addition. The only other concern is the licence, which seems not to have been chosen yet, although an OSI-approved variant is promised.

Update: Apparently, if I'd taken the trouble to install it, I would have seen that the licence is the Common Public Attribution Licence. (Thanks to Randy Metcalfe.)
