frp/Release.md

Improvements

• Building frp from source now requires Go 1.26.0 or later.

Fixes

• Updated dependencies to fix SSH tunnel gateway channel deadlocks and panics caused by malformed challenges from NTLM-authenticated HTTP proxies.
• Fixed VirtualNet routing issues during reconnection and shutdown, and excessive retries after repeated connection failures.
• Health checks now reset the failure count after success, so healthCheck.maxFailed applies to consecutive failures.
• Fixed control connections getting stuck after message write failures, which could block reconnection.
• Fixed incorrect daily traffic statistics around daylight-saving transitions and skipped local midnights.
• Fixed early-data loss in HTTP virtual-host CONNECT tunnels. Requests with a positive content length or transfer encoding now return HTTP 400.
• Fixed work connections remaining open when server-side bandwidth limiting is enabled for TCP, HTTP, and UDP proxies.
