This: http://codex.wordpress.org/Changelog/3.5 is not a changelog.
This: http://codex.wordpress.org/Version_3.5 gives a few changes, etc, but no list of files added and removed. Where might I find a list of ‘breaking changes’? Actions and Filters that work differently?
Where is the changelog for 3.5? where is the list of added removed files?
You can always use GitHub. WordPress has an official (view-only) GitHub repository, and GitHub has an excellent comparison feature.
Here’s the GitHub comparison of WordPress 3.4.2 vs 3.5.
