It's important to clarify an aspect of the release process.  During the generation of releases, the last-modified dates and times of all ASCII text files, including the changlog.txt files, are updated to reflect the release date and time.

This updating of dates and times may cause confusion.  If you compare the last-modified dates and times of the changlog.txt files listed on the download page with those in the downloaded release, please note that the dates and times for the downloaded files represent the release state, while those shown on the download page reflect the earlier, pre-release state.
