This release is only needed for the AUR due to an error in the previous release.
For full patchnotes on this release see https://github.com/OpenVR-Advanced-Settings/OpenVR-AdvancedSettings/releases/tag/v5.3.2.
The only difference is that the .zip and .tar.gz files here are slightly more up to date. The binaries in the other release are all completely up to date.
