We're likely to release Chamilo 1.8.8 beta this week (hopefully on Thursday). Please make sure you have a look at the pending bugs in http://support.chamilo.org/projects/chamilo-18 and see if you can help.
If you are a translator, please make sure your translation is ready at http://translate.chamilo.org. If you're sure your translation is only managed by you, you can export your language files from there, edit them with something like the phpLangEditor extension for Firefox, and import them again. This will probably be much faster.
If everything goes according to plan, we should be releasing a stable version on the 21st of April. You can test the application at any time (updated every 5 minutes) on http://chamilodev.beeznest.com and report bugs at http://support.chamilo.org/projects/chamilo-18/issues.
Chamilo is an open source software. It is free and relies on YOU to continue bringing the best of e-learning to its massive user base (380,000 users now).
If you need help fixing bugs, let me know!
