Changelog

v1.16.1 (2024-06-20)

Enhancements

  • Optimize cookie parsing by 10x (10x faster, 10x less memory) on Erlang/OTP 26+

v1.16.0 (2024-05-18)

Enhancements

  • Support x-forwarded-for in Plug.RewriteOn
  • Support MFArgs in Plug.RewriteOn
  • Add immutable directive to versioned requests in Plug.Static
  • Support disabling MIME type handling in Plug.Static

Bug fixes

  • Fix bug with discarded connection state in Plug.Debugger
  • Parse media types with underscores in them
  • Do not crash on max_age set to nil (for consistency)

v1.15.3 (2024-01-16)

Enhancements

  • Allow setting the port on the connection in tests
  • Allow returning {:ok, payload} on inform
  • Allow custom exceptions in validate_utf8 option
  • Allow skipping sent body on chunked replies

v1.15.2 (2023-11-14)

Enhancements

  • Add :assign_as option to Plug.RequestId
  • Improve performance of Plug.RequestId
  • Avoid clashes between Plug nodes

v1.15.1 (2023-10-06)

Enhancements

  • Add Plug.Conn.get_session/3 for default value
