CHANGELOGs inaccuracies

Hello.

I am reading changelogs from rails master git branch from time to
time, because I like to know what's new. But every time, there are
some errors. Mainly in version releases dates. For example in
actionpack changelog (https://github.com/rails/rails/blob/
6481bc5f49ef26e8fde68ac964dc984d12f33189/actionpack/CHANGELOG.md) is
last released version Rails 3.1.0. We all know, that latest stable
version is 3.1.3 released 20.11.2011 (by rubygems.org).

Is anyone responsible for CHANGELOGs ?
Would you like to merge pull request correcting those errors ? I want
to ask first, before I start working on this.
