It is now 0.10.xxx ... and before that it was 0.9 ; probably when it becomes 0.99, it will go to 0.100 and so on ... I highly recommend to anyone to avoid using Node in production until its developers grow up, and become responsible for a stable API, and not change their minds every 2 months.
Do you have any links that point to "the developers changing their minds every 2 months"? How have you been affected? As a node user for 2 years, my view is that the API has been fairly stable of late.
Please back this up with evidence.
The mailing list just had a long post by Isaacs about how 0.10 is the last release before 1.0 and that 1.0 should be backward compatible with anything you write for 0.10.
