Changes for version 0.001012 - 2026-01-01

  • New Features
    • PAGI 0.2 specification: Loop-agnostic apps, SSE POST support, keepalive events
    • Send-side backpressure to prevent unbounded memory growth under slow clients
    • Configurable write_high_watermark (64KB) and write_low_watermark (16KB) matching Python asyncio defaults for optimal memory/throughput balance
    • SSE disconnect reasons (client_closed, timeout, write_error, shutdown)
  • Bug Fixes
    • Fix Lint middleware to preserve original app errors instead of masking them
    • Fix SSE keepalive to use chunked transfer encoding
    • Fix missing IO::Async::Timer::Periodic use statement
    • Fix missing 'method' field in SSE test scopes (per spec line 624)
    • Fix WebSocket scope incorrectly including 'method' field in test client
    • Fix middleware class resolution for nested namespaces (Auth::Basic, etc.) using ^ prefix for fully-qualified class names
  • Improvements
    • Improved event loop portability (Future::IO now fully optional)
    • Improve max_connections auto-detection using getrlimit(RLIMIT_NOFILE) instead of sysconf(_SC_OPEN_MAX) for accuracy
    • Add fd_headroom config option (default 100) for max_connections calculation
    • Add TTY warning at startup when access_log goes to terminal
    • Security fixes from code review
    • PAGI spec compliance fixes for event validation
  • Build/Distribution
    • Replace Markdown::Pod with App::sdview for spec POD generation
      • Fixes =item - to =item * (proper POD bullet points)
      • Converts module names to L<> links for metacpan
