The full list is way too long to include here. If you're curious about anything specific, MrKraken seems to have a very comprehensive list.
I'll drop a quick highlight of his "Annoying Fixes" since those will probably stand out to most.
Annoying Fixes
Some of the biggest annoyances of recent patches have had some potential fixes, including using jump tunnels, they should now correctly deposit you at the destination and not back where you started. That bloody fuel notification is now fixed, sort of, it might still appear when you respawn, but there’s a check in place to clear it now.
Docking has proved far more reliable on PTU after several fix attempts and requesting ATC at a location that supports hangar landing should now correctly assign landing over docking
Double hangar doors at rest stop stations has been fixed, Stanton gateway which has constantly had a blocked large hangar was all clear to leave again on PTU.
Ship cleanup has been tweaked to be more aggressive in Nyx spawn stations & Grimhex, with there now being a 5 hour allowed idle time before getting deleted.
Several Onyx facility related fixes, including Jorret Dossier contract blockers.
Airlocks & loot are once again working in Pyro’s contested zones
