Unity 6.4 has arrived, representing another “Update Release” in the Unity 6 release cycle. Update Releases receive bug fixes and critical platform updates until the next release is published. Unity 6.3 is currently the version with Long-Term Support (LTS) status.
While Unity 6.4 does not introduce major headline features, it continues to build on previous versions with a range of quality-of-life improvements and represents further progress toward more significant future updates.
Some of the highlights in this release include the integration of existing packages directly into the engine. The Entity Component System (ECS), including Entities, Collections, Mathematics, and Entities Graphics, now ships with the Editor. This change supports the development team's goal of developing the engine and ECS together for a more cohesive experience. The Project Auditor package has also been integrated into the Editor and is now available without additional setup.
Unity's multiplayer Matchmaker has received several improvements, with the Unity Dashboard now providing access to Matchmaker logs, making debugging and monitoring easier. It also displays Matchmaker configuration history with timestamps, authors, and change diffs, providing visibility into configuration changes.
Another addition is support for OR operations in pools and filters using CEL expressions. This allows the creation of more flexible matching rules, where players can satisfy any of multiple criteria rather than requiring all conditions to be met. Additionally, Matchmaker now supports third-party hosting.
Another area of focus has been platform support, with an improved workflow for Adaptive Performance. It now features a redesigned UI for managing custom scalers, and the Basic provider has been extended to support PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X|S consoles. This makes porting titles to these platforms easier, enabling features such as automatic quality scaling and bottleneck detection. In addition, DirectStorage is now available for textures, meshes, and DOTS/ECS data, taking full advantage of the speed benefits of NVMe SSDs on Xbox consoles and PC.
There have also been general improvements across the board, including creating sprite atlases at runtime and customizing and extending the 2D rendering process in the Universal Render Pipeline (URP), enabling custom rendering and post-processing.
A pop-up during package installation in the Package Manager has been added to provide important information for safer project decisions. This pop-up requires acknowledgment before proceeding with the installation of unsigned packages or packages sourced outside of Unity.
The Editor has also received workflow and user interface improvements, including grid and snapping enhancements and the ability to dock overlays in dynamic panels to further customize the workspace.
