The Python Community announced the release of Python 2.5.4 late in December of 2008. Python 2.5.4 is a bug fixes release.
While ArcGIS 9.3.1 was shipped with Python 2.5.1, Python 2.5.4 has now been certified and is supported. In limited testing with ArcGIS 9.3, no issues were encountered. To take advantage of fixes in Python 2.5.4, it can simply be installed on top of Python 2.5.1. That means, it is not necessary to uninstall Python 2.5.1 first.*
To see and to download the release notes go here.
* If you uninstalled Python 2.5.1 and you work with the Spatial Statistics geoprocessing tools, you must reinstall Numerical Python (NumPy) from the ArcGIS installation DVDs.
For more information, see FAQ: Can Python 2.5.4 be used with ArcGIS?

So, is this something esri will be doing in the future as well, where updates to py will be certified and then posted to the blog
Python 2.5.4 was certified partly due to high user interest. In the future, I would expect to see such updates here on the Resource Center and/or as a knowledge base article on the Support Center.
David, have the Spatial Statistics geoprocessing tools been tested with newer versions of the numpy module (1.3.0 is now available)?
Hi Daniel–Some work has been done internally with more recent versions of NumPy without any problems, but it has not been thoroughly tested to this point.
This is good information. We have also run into issues with numpy 1.0.3.
Is there any new information on either further internal work or completion of thorough testing of numpy 1.3 and ArcGIS 9.3.1 to help make the case for updating our enterprise python installations?
David, can you give me a hint if you have done more testing of a newer version of NumPy? It would be nice to hear if one can update the version of NumPy for the use with ArcGIS. In one of my projects we want to use SciPy for the calculation of NNLS (non negative least squares). But SciPy depends on NumPy >= 1.3 while ArcGIS depends on NumPy = 1.0.3 It would be nice to hear if one can safely update NumPy without breaking a functionality of ArcGIS 9.3.1
Best regards,

David,
Do you know whether ArcGIS 10 python will be extended to support the creation of map services etc within ArcGIS Server. I would love to be able to script this rather than having to use ArcCatalog each time.
Thanks
Andy
