v8.0.2

  • Bugfixes
    • Anchor PROXY protocol v1 regex to string start and enforce max line length to prevent injection via crafted request bodies (#3944)
    • Parse PROXY protocol header only on the first request per connection to prevent spoofing on keep-alive connections (#3944)

Security advisories

v8.0.1

  • Bugfixes

    • Fix prune_bundler stripping user-configured BUNDLE_* env vars (e.g. BUNDLE_WITHOUT) on re-exec, which caused workers to crash on boot (#3929)
  • Performance

    • Use blocks for debug logging to avoid creating log messages when debug is disabled (#3920)
  • Docs

    • Fix incorrect hook names in gRPC docs (#3923)
    • Reword v8 upgrade guide IPv6 bullet for clarity (#3928)

v8.0.0 - Into the Arena

Read our Version 8 Upgrade Guide.

  • Features

    • Add env["puma.mark_as_io_bound"] API and max_io_threads config to allow IO-bound requests to exceed the thread pool max, enabling better handling of mixed workloads (#3816, #3894)
    • Add single and cluster DSL hooks for mode-specific configuration (#3621)
    • Add on_force option to shutdown_debug to only dump thread backtraces on forced (non-graceful) shutdown (#3671)
    • Add API to dynamically update min and max thread counts at runtime via update_thread_pool_min_max and ServerPluginControl (#3658)
    • Use SIGPWR for thread backtrace dumps on Linux/JRuby where SIGINFO is unavailable (#3829)
  • Bugfixes

    • Fix phased restart for fork_worker to avoid forking from stale worker 0 when it has been replaced (#3853)
  • Performance

    • JRuby HTTP parser improvements: pre-allocated header keys, perfect hash lookup, reduced memory copies (#3838)
    • Cache downcased header key in str_headers to avoid redundant String#downcase calls, reducing allocations by ~50% per response (#3874)
  • Refactor

    • Collect env processing into dedicated client_env.rb module (#3582)
    • Move event to default configuration (#3872)
  • Docs

    • Add gRPC guide for configuring gRPC lifecycle hooks in clustered mode (#3885)
    • Add 7.0 upgrade guide, move 5.0/6.0 upgrade guides to docs directory (#3900)
    • Correct default values for persistent_timeout and worker_boot_timeout in DSL docs (#3912)
    • Add file descriptor limit warning in test helper for contributors (#3893)

Puma 8 changed the default bind to IPv6 (::) when an IPv6 interface is
available. Heroku's router connects over IPv4, so an IPv6-only bind would
cause an H20 boot timeout. Pin 0.0.0.0 to keep the bind deterministic.
