SteamDB Registers Call of Duty Dev Build 21245352, No Official Patch Notes

A developer build for Call of Duty was registered on SteamDB on January 13, 2026, under build number 21245352, but no official patch notes accompanied the entry. The public SteamDB record lists the build ID and the depots affected and shows changed files across three depots. The entry itself states, "There are no official patch notes available for this build besides the list of changed files in 3 depots."

That listing matters because SteamDB entries act as an early signal that server-side changes, hotfixes, or platform packaging steps occurred on a given date. Even when publishers do not publish accompanying notes, the presence of a dev build confirms active backend work on the PC build. For anyone tracking hotfix timing, preload updates, or rapid server-side tweaks, the build ID and depot changes provide concrete timing and packaging context.

The SteamDB entry did not include explanations of what the changed files modify, so players should not assume visible gameplay alterations were deployed to live servers. Dev builds often reflect internal packaging or configuration updates, staged test fixes, or data pushes that support future public patches. For competitive players, streamers, and server admins, these subtle updates can explain brief matchmaking quirks or temporary server behavior that otherwise looks mysterious.

Community tech investigators and data miners will use the listed depot changes to narrow their searches and watch for follow-up builds that clarify scope. The three depots referenced in the record point to where files were altered, which helps pinpoint whether changes are likely client-side, server-side, or related to auxiliary systems like anti-cheat or assets packaging. Those tracking exploit fixes or weapon tuning should log the build ID 21245352 as a timestamp for when backend churn occurred.

If you experience issues after January 13, check Steam's client tools and official channels for later announcements. Verify integrity of game files if crashes or corrupted assets appear, and monitor SteamDB for subsequent entries that may list more detailed changes. Watch developer channels and patch notes pages for an official follow-up; absence of immediate notes does not rule out staged rollouts or staggered announcements.

This item is a reminder that not every technical change ships with a press release. The SteamDB entry confirms active maintenance on the PC side and gives the community a marker to follow. Expect additional builds or public notes if these depot changes were preparatory steps for a broader update.
