Bungie has released the patch notes for Lightfall, and of course a significant amount of it is devoted to changes that were already announced. Check out the full patch notes on their blog here. However, there are some things in here that were not previously announced, so in this post I'll list out everything new!

Miscellaneous

Competitive Rift & Showdown have reduced revive delay time 2s -> 1.5s, reduced respawn time 7s -> 5.5s
Retuned Vanguard map and mode multiplier, balancing for score-per-hour, not score-per-attempt
Added on-screen health bar to strike bosses that were missing them
Artifice armor now drops with higher stats
Players can access the PGCR during the mission end countdown by pressing the button that normally brings out their ghost. Holding the button still goes to the director.
Updated rank tooltips so all tooltips now include a streak tracker and add a section that shows a player's total reputation rank points
More items can be tracked at once:
- Up to three guardian rank objectives can be tracked
- Up to six non-guardian rank objectives can be tracked (this presumably includes seasonal challenges and triumphs)
Lore, weapon pattern/catalysts, medals, and stat trackers have moved to the collections screen
Most armor mods that are based on weapon damage type also have a harmonic version, which is discounted when the weapon's damage type matches your subclass damage type.
Champions now correctly stun even when they're playing another animation, such as a spawn-in.
Champion stun time is now consistent across all Champions.
- This used to be dependent on the animation length, leading to slightly different times between combatants.
Weekly powerful rewards have been removed from Throne World and added to Neomuna.
Focusing seasonal gear will require multiple seasonal engrams
Completing activities throughout the game will occasionally reward a seasonal engram or key
Playlist versions of the new seasonal battlegrounds have one chest at the end of the activity. Opening it without a key will give you a seasonal weapon or armor. Opening it with a key will give you a seasonal engram and either a deepsight resonance that you are missing, or a high stat piece of seasonal armor.
Added support for NVIDIA Reflex on PC

Balance

Exotic Armor

Khepri's Sting: Truesight is now granted when damaging an enemy with a smoke bomb. Additionally, when you have an undetonated smoke bomb on the battlefield and have not been made invisible by a smoke bomb, you gain significantly increased melee energy generation.
Heart of Inmost Light: Reduced duration of the empowered ability buffs in PvE to five seconds (down from 10 seconds). Reduced bonus class ability regeneration while empowered to +25% per stack in both PvE and PvP (down from +150% and +38%, respectively).
- This change is intended to decrease how easy it is to get and maintain a 2x empowerment bonus in PvE, as well as reduce the total amount of bonus ability energy provided. The goal is for Heart of Inmost light to remain strong in ability-focused builds, while giving room for other Exotics to shine as well.
The Bombardiers now cause targets damaged by its explosive to become severed when used by a Strand Hunter.
Chromatic Fire has been updated to work with Strand.
Mantle of Battle Harmony updated to work with Strand.
Verity's Brow updated to work with Strand.
Felwinter's Helm triggers weaken burst off Strand melees.
Claws of Ahamkara will not provide an additional melee charge when equipped to a Strand subclass.
