Revision history for Perl extension Feersum

1.509 Tue Oct 20 14:54:11 2026 +0300
        - security and robustness hardening across HTTP/1, HTTP/2 and TLS
        - enforce retired generation drain deadlines through reload and shutdown

1.507 Fri Sep 25 10:49:04 2026 +0300
        New:
        - multiple server instances (new_instance) and multiple listeners
          per instance, IPv6 among them
        - TLS 1.3 via picotls+openssl: per-listener certificates, SNI vhosts
        - HTTP/2 via nghttp2: multiplexing, streaming, extended CONNECT
          (RFC 8441), rapid-reset (CVE-2023-44487) and ping-flood
          (CVE-2019-9512) protection
        - PROXY protocol v1/v2, including TLVs
        - reverse_proxy mode: take client_address and url_scheme from
          X-Forwarded-For/-Proto behind a trusted upstream; off by default
        - SO_REUSEPORT, sendfile
        - timeouts and limits: header_timeout, write_timeout, linger_timeout,
          max_connections, max_body_len, max_uri_len, max_read_buf,
          max_accept_per_loop, max_h2_concurrent_streams, max_h2_conn_body,
          wbuf_low_water
        - introspection: active_conns, total_requests, access_log,
          pause_accept/resume_accept, set_psgix_io
        - psgix.h2.trailers, psgix.h2.extended_connect, psgix.h2.protocol,
          psgix.proxy_tlvs
        - psgi.input gains getline, getlines and <$fh>
        - Feersum::Runner: hot_restart, preload_app, daemonize, pid_file,
          user/group, after_fork, access_log, graceful_timeout,
          startup_timeout, max_requests_per_worker
        - bin/feersum native mode with full Runner option parity

        Incompatible with 1.505:
        - requires Perl 5.14 (was 5.8.7)
        - the Feersum object is no longer a hashref; use the public API
        - psgix.input.buffered is no longer advertised (psgi.input is
          forward-only; Plack buffers the body when it is unset)
        - a UTF8-flagged response string whose characters all fit in a byte
          is sent as those bytes, like every other PSGI server
        - a 1xx final status is refused (101 excepted); a status above 599
          answers 500
        - CR or LF in the status line, and a control character in a response
          header (a tab is allowed in a value), are refused (CWE-113)
        - psgi.input is always present, per PSGI 1.1
        - a graceful stop, worker retirement and hot-restart handover exit
          via POSIX::_exit: END blocks do not run and buffered STDOUT is
          lost (set $| = 1 or log to STDERR)

        See the UPGRADING section in the docs for behaviour changes that
        bite with no code change (tighter default limits among them).
