Moodle 2.0 RC1 was released recently, and you can get daily builds from the Moodle download page.
NOTE: this is not the final release yet!
This milestone reflects the fact that the 2.0 feature set is now completely implemented and available in the core code.
You can read more about 2.0 in the Moodle 2.0 RC1 release notes.
The final release should be in a month or so. Until then:
- all the core developers will continue responding to your feedback and bug reports in the Moodle Tracker and the forums, fixing bugs and improving overall stability,
- our testers will also continue working on Moodle 2.0 QA Cycle 2, to re-test all the features in that list, and
- we'll be converting all the (rather customised) moodle.org sites to Moodle 2.0
