I'm making available RDF news files with pointers to the latest changes in the Python (and ReportLab) CVS repositories (using ViewCVS on SourceForge):
There is also one such file for Stackless Python, but given that there is no ViewCVS for it (yet), the links point some- where into Nirwana:
http://me.in-berlin.de/%7Edarwin/cvsstpy.rdf (Stackless, 72 h)
All are updated each hour. You can point any GUI tools like SlashDock* (on OS X) to them and save time by forgetting about typing the respective URLs or CVS commands for quickly tracking changes.
BTW, another interesting news file is ActiveState's one, which will let you keep an eye on the newest Python recipes in their cookbook website:
