Jenkins MCP Server v2.10.1

Released 2026-08-14.

Highlights

• Normal Minibridge session cleanup no longer produces false backend WebSocket
  errors on otherwise healthy replicas.

New Features

• None.

Improvements

• The Minibridge image now builds the exact checksum-pinned 0.8.0 source commit
  with a narrow reviewed backport, and runs the affected upstream backend unit
  tests before producing the multi-architecture binary.
• The k3s smoke opens and closes an MCP session directly on each of two replicas,
  waits through Minibridge's idle-session deadline, and rejects the former false
  error in either pod's logs.

Bug Fixes

• Minibridge's WebSocket dependency can report net.ErrClosed when Minibridge
  intentionally closes an idle internal session. The bundled backend treated
  that local shutdown as an unexpected transport failure and emitted
  Backend websocket has closed at error level. The backport now classifies
  net.ErrClosed, including wrapped forms, as normal cleanup while preserving
  error reporting for resets and other genuine transport failures.

Breaking Changes

• None.

Known Issues

• None known.

Security

• None. The backport changes close-error classification only; policy, TLS,
  credentials, and network exposure are unchanged.

Upgrade Notes

• No configuration change is required. Upgrade both direct and -minibridge
  image/chart pins together as usual. The fix affects only the Minibridge image.
