Blizzard Entertainment released a minor update for Diablo 4 on September 9, 2026. The patch, which brings the game to version 3.1.4 (Build #73548), is a technical rollout focused on client stability shortly before the transition to the next season.
Platform Version Mapping
While the internal build remains consistent across systems, the version numbering displayed on consoles differs from the PC client. The identifiers for the September 9 update are:
- PC: Version 3.1.4
- PlayStation 4: Update 2.17
- PlayStation 5: Patch 01.117.000
- Xbox Series X/S and Xbox One: Version 3.1.4
Stability and Performance Adjustments
Blizzard has not released official itemized patch notes for Version 3.1.4 as of the initial rollout. The update file size is approximately 150 MB on PC, indicating a concentrated set of technical corrections rather than new gameplay content. Based on community tracking and early reports, the update primarily addresses:
- General stability improvements to the game client.
- Gameplay performance optimizations.
- Specific fixes for reported crashing issues.
Because there are no balance changes included in this build, character builds and itemization remain unchanged from the previous Version 3.1.3, which was released on August 12, 2026.
Timeline for Season 15
This stability update serves as a final preparation for the end of the current season. According to Blizzard Forum reports, the 3.1.4 update ensures the client is optimized before the expected launch of Season 15 on September 15, 2026. The upcoming season is tentatively titled “Season of Infernal Chaos.”
Players must download this update to maintain access to online features before the upcoming seasonal reset.
