Patch notes are up : https://www.bungie.net/en/News/News?aid=12773

In crucible:
-Guardians no longer drop Special ammo on death
-Lowered the amount of Special ammo picked up from crates (from 50% to 25%)
-Special Ammo crate respawn time raised (from 45 seconds to 120 seconds)
-Increased drop radius when a friendly picks up a Special crate (from 20 meters to 100 meters)
-Slightly increased interaction time on Special Ammo crate (from 0.1 seconds to 0.8 seconds)
-Reduced the number of Special crates on the maps and relocated them (from 6-8 crates to 3-5 crates)
-Special and Heavy ammo bricks now despawn when a player dies or on a timer (20 seconds for Special, 30 seconds for Heavy)

This is going to have some serious ramifications; specials that spawn with double ammo in reserve are very high on my list of wants at the moment. Invective and Icebreaker stock going way up. Primary exotics just became the new meta.
