Python for S60 has been almost totally rewritten, it seems (around the Python 2.5.1 core), with a huge version number jump to v1.90, available here. The most obvious changes are for developers, including a new GUI-driven SIS packaging tool and far better support for 'standard' Python libraries. Here's the download page, here's the readme that you'll want to scan over (it looks like it's something of an interim release before v2.0) and here's where I read about it.
