Full changelog

Security

  • Bumped ws 8.20.1 → 8.21.0 to pick up the upstream fix for a remote memory-exhaustion DoS (responsibly disclosed by Nadav Magier).

A peer streaming a high volume of tiny fragments or data chunks could OOM the receiving ws server or client. safari-mcp uses ws for the Safari extension WebSocket bridge, so the new upstream cap on retained fragments now applies. No API changes — drop-in upgrade.

Resolves Dependabot alert #18.
