The client app is not indicating that 1.32.3 for Windows is available yet but the download link on the site has been updated.
Tailscale client downloads are extremely slow at the moment, so I suggest you distribute one copy manually around your tailnet rather than bogging down their servers even more.
The Windows client caches the current version for a while, so may not yet have v1.32.3 available on your device.
In that case, you can still pull the latest release from http://pkgs.tailscale.com/stable.
Tailscale admin here, politely requesting client update push capability. Being able to see endpoint version is helpful, I will be suspending unpatched endpoints in the near future.
Or Get Tailscale in the Windows Store so it could auto update for all the endpoints out in the wild I don't control (company laptops, users home PCs, etc). Trying to get TEN people to manually update today was a pain, I can't imagine even triple that.
