Here are the patch notes for the Call of Duty: Vanguard Season 1.5 update.

The first major update for Call of Duty: The Vanguard 2022 is fast approaching and the patch notes are already available.
Sledgehammer Games today revealed that the Avant-garde The Season Update 1.5 will go live today, January 11 at 6:00 p.m. CT. The patch is expected to feature a plethora of changes, including bug fixes, weapon balancing, and spawn logic tweaks.
Especially for fans of public multiplayer, the incendiary grenades have been nerfed. Dauntless and Fortified perks have also been adjusted to help players deal with the multiple sources of fire damage in Avant-garde. Sledgehammer has even “reduced the amount of time players are affected by stun grenades,” which should be a welcome change for competitive and casual players.
In addition, the sequence of mortar barrage eliminations should be slightly less embarrassing to move forward since its duration and the number of shots have been reduced. The M1 Garand, Type 99, 3-Line Rifle, and Kar98k were the weapons targeted by Sledgehammer in this patch. Developers too “adjusted some of those crazy check spawns and fixed a few issues causing packet burst.
Sledgehammer made sure to let fans know he had heard the community’s comments and reviews on Avant-garde. The developers said we “can expect more updates to come. Avant-garde before season 2.
