Changelog

0.2.5 — 2026-03-30

Changed

  • OMQ_DEV env var — require "omq" replaced with require_relative when OMQ_DEV is set, loading the sibling omq source tree instead of the installed gem. Gemfile uses the same var (replaces DEV_ENV).

0.2.4 — 2026-03-27

Fixed

  • CURVE handshake deadlocks with buffered IO — missing io.flush after greeting, HELLO, INITIATE (client) and greeting, WELCOME, READY (server) writes caused both peers to block on read
  • Tests used minimum_write_size: 0 which bypassed IO buffering entirely, masking the flush bug

0.2.3 — 2026-03-26

Changed

  • Move version constant from OMQ_CURVE_VERSION to OMQ::CURVE_VERSION (also available as OMQ::Curve::VERSION)

0.2.2 — 2026-03-26

Improved

  • Inline frame wire encoding in encrypt, bypassing Frame.new.to_wire and its IO::Buffer allocation — especially helps larger messages (4KB TCP: +87% vs v0.2.0)

0.2.1 — 2026-03-26

Improved

  • 15–55% throughput improvement by bypassing Command.from_body in the MESSAGE decrypt hot path — parses the prefix directly via byteslice instead of allocating an IO::Buffer

0.2.0 — 2026-03-26

Changed

  • New API: OMQ::Curve.server(pub, sec) and OMQ::Curve.client(pub, sec, server_key: k) replace verbose per-socket options (curve_server, curve_public_key, etc.)
  • OMQ::Curve is a convenience alias for OMQ::ZMTP::Mechanism::Curve
  • Requires omq ~> 0.2

Added

  • omq-keygen executable for Z85 keypair generation
  • examples/reqrep/ with encrypted server/client scripts

0.1.0 — 2026-03-25

Initial release. CurveZMQ (RFC 26) encryption for OMQ.

  • Curve25519-XSalsa20-Poly1305 encryption and authentication
  • 4-step handshake (HELLO/WELCOME/INITIATE/READY)
  • Anti-amplification and server statelessness per RFC 26
  • Client authentication via allowlist or custom callable
  • Z85 key encoding/decoding
  • Requires libsodium via rbnacl
