IAP: # Changelog
## [4.3.0] - 2022-06-16
- GooglePlay - API
IGooglePlayConfiguration.SetQueryProductDetailsFailedListener(Action)called when Unity IAP fails to query product details. The
Actionwill be called on each query product details failure with the retry count. See documentation "Store Guides" > "Google Play" for a sample usage.
- GooglePlay - API
- Version Control: Renamed "Invite members to workspace" option to "Invite members to organization"

Graphics: 2D Textures with multiple faces or images now correctly update their hash values when any face/image is changed and not just the first one (UUM-2506)
Graphics: Fixed a regression where calling the the Texture2D.Resize method with a Texture format parameter caused the underlying GraphicsFormat to flip color spaces on each call. (UUM-1804)
Graphics: Fixed AssetPreviews + texture preview window for ASTCnm/Plain normal maps. (UUM-7833)
Graphics: Fixed numerous cases where mini-thumbnails would not match the expected visual look when using linear project color space. (UUM-7833)
Graphics: Fixed Single Channel Red mini-thumbnails not actually being red-only. (UUM-7833)
Graphics: Fixed undefined behaviour occurring with AssetPreview for Single Channel Alpha texture types. (UUM-7833)
Graphics: Shadow casters with different UnityPerMaterial aren't properly SRP Batched. (1421660)
Graphics: Switching vsync mode while in a Metal player could sometimes cause a freeze due to the vsync status not syncing correctly before waiting on the frame present - this has been fixed. (UUM-5547)
Graphics: The generated mini-thumbnail of TextureGenerationOutput will now properly set its expected stored color space. (UUM-7833)
IL2CPP: Avoid a possible crash when a Unity player is unloaded and reloaded. (UUM-2660)
