Links to stable releases changelogs
These only contains a quick overview of the changes that took place between two stable releases. In any case, please refer to the release's documentation to have the full details about new features as well as the full, detailed svn changelog if you need to know more details about what happened in a development cycle. Such svn changelog can be generated by typing the following command in a terminal (from your local copy of the repository):
svn log -r534:HEAD > Changelog.txt
That would give you the whole commits comments between svn version 534 and the current HEAD. In order to know which svn version matches which stable release, please go to the tags repository: the revision for each release is written in the third column.
