Is Python2.6 stable enough for production use?

Question

Or should I just stick with Python2.5 for a bit longer?

Answer 1

From python.org:

The current production versions are Python 2.6.2 and Python 3.0.1.

So, yes.

Python 3.x contains some backwards incompatible changes, so python.org also says:

start with Python 2.6 since more existing third party software is compatible with Python 2 than Python 3 right now
