The beta is available from the Steam library game properties "Betas" dialogue, branch "16_update14version_rc".

Release Notes for this version:
changes
- workingaround nVidia RTX and (newer) AMD gpus not accessing the previous 3rd and 4th texture file during the grass shader stages which resulted in missing flowers, every flower texture is now derived from 1 single common texture file
- a 4th flower was added making the common texture file contain 4 flower textures
- the previous texture-file-number-based distinct flower density across the grass is lost, all flowers have the same density across the grass now
- dandelion seed texture changed
- game engine OpenXR plugin provider changed, SteamVR is not opened anymore during launch when available
- beach ocean audio volume starts to falloff farer away
- music max volume slightly decreased
improvements
- input configuration; a false actuation of an analog input as delivered by the game engine was still observed but was remedied by actuating the intended input stronger
fixes
- custom music starting from beginning when not having changed it when applying settings again
known issues
- disabling VR results in the screen showing the image for the VR hmd left eye
- custom music resets itself 1 time after playing the first tenths of the first second
