The update focuses on eliminating visual and mechanical issues for spectators. Fixed post-processing glitches when switching between players, x-ray silhouette sticking, and spectator damage overlay effects. A new weapon_accuracy_stack_boost_limit variable has been added for fairer inaccuracy application when playing on ladders with multiple teammates, and grenade jump throw consistency has been improved.

For community server administrators, this update brings significant API expansions. New methods have been added for managing player money (AddMoneySpendableNow, GetMoneyEarnedForNextRound), equipment control (HasHelmet, SetHasHelmet, IsScoped), weapon inspection (IsSilencerOn), and round event handling (OnBeginRoundRestart, SetRoundRemainingTime). The logic for OnPlayerUse activator and caller has also changed, allowing plugin developers to work more flexibly with player-entity interactions on maps.

The de_cache map received geometric adjustments around windows and vent entrance, with improved window cover models for decal display on hits. It's recommended to verify clipping and collision in window areas if you use custom models on your servers.
