Big Thanks to @niiln, @thisleo, @AxelTheAvali, @Meister1593 and Ghost for helping to test and send logs/videos on Vive Focus 3 and Pico Neo 3.

ALXR v0.9.0

• Fixes/improves the following for Pico Neo 3 Link
  • Fixes start-up crash
  • Fixes issues with controller poses
    • Please note you may notice a tiny amount of lag, this is due to a workaround for bugs in current version of Pico Neo 3's OpenXR runtime.
  • Improvements to suggested bindings for Pico Neo 3 controllers.
• Enables TCP nodelay on the client-side, this may give a small latency improvment for TCP connections.
  • Previously this was only enabled on the server-side.
• Upgrades the cross-vendor OpenXR loader to version 1.0.24
• Switches the OpenXR controller pose from grip to the aim-pose for all suggested bindings, this pose type much better matches the server side controller emulation profiles
  • If you have previously applied position/rotation offsets please revert them as they will no longer be valid.
• Fixes de-saturated render results when using the latest version of Monado for android
• Adds new parameter to allow disabling sRGB linearization on the command line.

Big Thanks to @paul-maidment, @starsitoo, and Rui Pereira for helping to test, send logs/videos, and fixing issues on Pico Neo 3 (Link).

ALXR Client v0.8.0

• Now compatible with v18.2.3 ALVR server.
• Adds supports for audio & microphone streaming on all Android flavors (Quest,Pico,Generic,etc) (by makomk thanks!)
• Adds support for requesting permissions on Android
• New UWP (x64 & Arm64) Builds for Hololens 2 (and Windows)
• Adds support for XR_MSFT_hand_interaction, XR_MSFT_unbounded_reference_space OpenXR extensions.

• Fixes a bug on Quest where restarting the client requires starting multiple times to run.
• Fixes missing x264/5 shared libraries for portable / --bundle-ffmpeg builds.

From this point on, builds of Monado for Android will no longer be provided here as Monado is a constantly evolving project. CI builds are obtainable from Monado's repository (pick a successful build, click on the "..." button and download the relevant "artifact"). Currently only debug builds available but there is a pending merge request to enable release builds too. A build of the OpenXR android runtime broker is still available from the previous release here.

The wiki docs on ALXR has been updated, please refer there for further details.
