Revision history for Unblock-HTTP3

0.03  2026-10-04
    - Require Uniform::HTTP 0.06 for its header-only native FastPath ABI.
    - Inspect canonical outgoing Request and Response objects directly in XS,
      avoiding Perl FastPath views and temporary HTTP/3 wire-field arrays.
    - Retain decoded nghttp3 header blocks in native connection state and build
      exact canonical Uniform messages directly from validated native byte spans.
    - Preserve HTTP/3 semantic validation, Cookie coalescing, field-section
      limits, message lifecycle state, and canonical Uniform object ownership.
    - Add native-path loopback coverage and HTTP-layer microbenchmarks.
    - Add a public versioned native consumer ABI for XS event frameworks and
      HTTP libraries, with an installed C header and persistent Connection
      context.
    - Expose native service, request, Transaction polling, canonical Uniform
      message access, response sending, and failure-state inspection without
      exposing libnghttp3 or private storage.

0.02  2026-10-04
    - Require Uniform::HTTP 0.05 and use exact canonical Uniform::HTTP::Request
      and Uniform::HTTP::Response objects throughout the public HTTP message API.
    - Remove the Unblock::HTTP3 Request and Response subclasses; HTTP/3
      priority and stream-abort state now belong to Transaction.
    - Use Uniform::HTTP::FastPath ABI 1 for outgoing wire-field access and
      trusted construction of already-validated received HTTP/3 messages.
    - Record local and remote RESET_STREAM and STOP_SENDING codes explicitly
      on Transaction without adding transport state to Uniform message objects.
    - Add RFC 9412 ORIGIN support through libnghttp3.
    - Add server origins configuration and client peer_origins inspection.
    - Add independent quic-go client interoperability against an
      Unblock::HTTP3 server.
    - Expand interoperability documentation to cover both client and server
      directions.
    - Add repeatable real UDP/TLS/QUIC/HTTP/3 loopback performance benchmarks.
    - Add split-process benchmarks to separate client/server event-driving cost.
    - Add HTTP/3-layer microbenchmarks for Uniform message construction,
      wire-field preparation, field-section accounting, native nghttp3
      submission, and streaming body-copy cost.
    - Avoid rebuilding the connection-specific header lookup for every field,
      reducing representative HTTP/3 wire-field preparation cost.
    - Retain outgoing body chunks as dedicated Perl scalar storage in native
      state instead of allocating and copying a second C byte buffer, while
      preserving caller-mutation isolation and ACK-driven release.
    - Add incoming-body microbenchmarks for native DATA events, buffered
      accumulation, streaming delivery, and complete buffered construction.
    - Retain owned incoming DATA scalars directly in streaming Body::Reader,
      removing a second Perl string copy while preserving receive-credit and
      backpressure semantics.
    - Keep small buffered DATA chunks on the compact scalar path and retain
      owned chunks of 16 KiB or larger until one final message-body coalescing,
      reducing repeated large-body copies.
    - Add a normative RFC conformance audit suite for malformed control,
      QPACK, priority, push, and stream-lifecycle input.
    - Treat peer closure, reset, or STOP_SENDING of critical HTTP/3 streams
      as H3_CLOSED_CRITICAL_STREAM.
    - Reject duplicate peer SETTINGS with H3_SETTINGS_ERROR so extension and
      remembered 0-RTT state cannot become ambiguous.
    - Reject unauthorized server push with H3_ID_ERROR when no push capacity
      has been advertised.
    - Coalesce decompressed Cookie field lines before exposing canonical
      Uniform HTTP messages.
    - Defer server application delivery of 0-RTT Transactions and Datagrams
      until the QUIC handshake completes and the early data has not been
      rejected.
    - Enforce the 0-or-1 value rules for Extended CONNECT and HTTP Datagram
      SETTINGS in the HTTP/3 SETTINGS inspector.
    - Enforce the RFC 9297 Capsule-Protocol response-status restriction.
    - Document the remaining libnghttp3 limitations for malformed-message
      stream scope and RFC 9218 invalid-parameter preservation.

      outside Unblock::HTTP3.
