v0.29.3

Minimum supported Tailscale client version: v1.80.0

Changes

• Fix tagged node stuck expired after tailscale logout, unable to re-authenticate #3394
• Re-registering a tagged node with a different pre-auth key now applies the new key's tags instead of silently keeping the old ones #3394
• Fix re-authenticating an already-tagged node with --advertise-tags being rejected when the authenticating user owns the tags #3394
• Fix ephemeral nodes lingering as disconnected after reconnect churn #3383
• Fix node registration falsely returning 401 registration timed out when auth completes as the request context expires #3392
• Check the machine key on the followup registration poll so a leaked auth ID cannot return the registering user's identity #3393
• Reject /key requests below the supported capability version floor, matching /ts2021 #3391
