Santiago, if you are still running 2.6.5 code, use the most recent 2.6 docs at
http://docs.python.org/release/2.6.6/
This will have all the corrections made after the 2.6.5 release. Contrary to what you might think the header line says, there is no particular connection between the 2.6.5 code release and the obsolete 2.6.5 doc release.

George, since the continuously updated x.y docs released with x.y.z really document x.y and not each x.y.z bugfix release, I am a bit surprised that they are labelled x.y.z docs with the claim "This is the documentation for Python x.y.z", especially since they are updated after the x.y.z code release.

The current '2.7.2' docs, last updated today, would more truthfully be called either '2.7' docs or '2.7.3a0' docs, as they are are a preview of what will be released with 2.7.3 and are not what was released with 2.7.2. If there *were* (unusally) any new features in 2.7.3a0, they would already be listed in the so-called '2.7.2' docs. (There *was* such a bugfix addition for difflib.SequenceMatcher in 2.7.1, and I presume it did appear in the updated '2.7.0' online docs.)

I am not sure we should have obsolete snapshot versions online. They only serve to be an attractive nuisance as illustrated by this issue. With the initial 3.3 release being called 3.3.0, there would be no ambiguity in calling the 3.3 docs just that.
