### [IMPORTANT] Obi 7 is a major update. If you're updating from an older version, it will require you to redo the setup most of your existing Obi-related functionality. It is recommended to use Obi 7 on new projects only, or if you must update an existing one, plan accordingly and set aside some time to perform the update.

## [7.1.1]

## Fixed

- Issue in ObiColliderWorld that would cause particles to stop reacting to colliders when destroying and re-instantiating a prefab containing an actor in the same frame.

## [7.1]

### Added

- Solvers can now optionally enforce boundary limits, so that particles can't go outside those limits. This is often more convenient than manually placing invisible colliders for the same purpose.

- Dynamic ObiParticleAttachments now have a "projection" boolean, when enabled it forces the rendered position/orientation of the attached particles to match that of the attachment location, even if the constraint doesn't fully converge. This is useful to avoid visual gaps under extreme conditions.

- Actors now have a "mass scale" parameter, that multiplies the mass of all particles in the blueprinyt at the time of loading it into the solver. This is handy to create actors of different masses without the need to create a new blueprint.

- ObiForceZones now have a "color" parameter, that can be used to change the color of particles entering the zone.

### Changed

- Improved performance for large amounts of static colliders: they're not processed at all during ObiSolver.Update().

## [7.0.5]

### Fixed

- InvalidOperationException in Burst backend when having simulateWhenInvisible = false and solver not seen by any camera.

## [7.0.4]

### Added

- Support for extra bones added at runtime to a full-body softbody character. Bones with names that don't match the ones in the blueprint are ignored.

### Fixed

- Bug that caused inactive particles to still be rendered by ObiInstancedParticleRenderer.

- Property painting in the blueprint editor didn't work correctly with blueprint rotation values other than zero.

- ObiSoftbodySkinner didn't take blueprint rotation/scale correctly into account.

- ObiSoftbodySkinner influence texture export not working sometimes (due to GL.LoadOrtho bug in Unity)

- Bug that preventing pin constraints' break threshold from working when using the Compute backend.

## [7.0.3]

### Added

- Object layer support for all renderers.

- New "Synchronous Fixed" solver synchronization mode, similar to Obi 6, offers tighter integration with rigidbody physics.

## [7.0.2]

### Fixed

- Solvers not placed at the scene origin would result in actors having incorrect motion blur in HDRP.

- Fixed issue when disabling all solvers and colliders simultaneously: ipon re-enabling them, the colliders would be ignored.

## [7.0.1]

### Added

- Render layer mask support to ObiSoftbodySkinner.

### Fixed

- Having a ObiParticleRenderer with no material applied resulted in a exception in builds due GetInstanceID() returning 0 in editor but raising a nullref exception in the build.

## [7.0]

### Added

- Compute shader based GPU solver backend.

- More efficient solver update cycle, that also removes the need to have ObiUpdater components.

### Changed

- Rendering system is now fully multithreaded, integrated with the solver backend.

### Removed

- Native library based 'Oni' solver backend.

- ObiUpdater and all derived classes have been removed.
