I could find no link to the bugs fixed in the release notes for 6.0.5.
Every official announcement, like the one for 6.0.5, points to related lists. All of them are listed in relevant subpages of release plan. But those lists only show the commits that explicitly mention bug numbers in their commit messages. There is always a number of commits that don’t mention a bug. The full list of changes is the git log.
I add that on the download site the release notes page contains the links to the fixed bugs.

The official announcement links to these changelogs, which are hosted on the TDF wiki. You can find lists for all versions in the Release category on the wiki.
