[Sergey Kandaurov]

Changes with nginx 1.27.4                                        05 Feb 2025

    *) Security: insufficient check in virtual servers handling with TLSv1.3
       SNI allowed to reuse SSL sessions in a different virtual server, to
       bypass client SSL certificates verification (CVE-2025-23419).

    *) Feature: the "ssl_object_cache_inheritable", "ssl_certificate_cache",
       "proxy_ssl_certificate_cache", "grpc_ssl_certificate_cache", and
       "uwsgi_ssl_certificate_cache" directives.

    *) Feature: the "keepalive_min_timeout" directive.

    *) Workaround: "gzip filter failed to use preallocated memory" alerts
       appeared in logs when using zlib-ng.

    *) Bugfix: nginx could not build libatomic library using the library
       sources if the --with-libatomic=DIR option was used.

    *) Bugfix: QUIC connection might not be established when using 0-RTT;
       the bug had appeared in 1.27.1.

    *) Bugfix: nginx now ignores QUIC version negotiation packets from
       clients.

    *) Bugfix: nginx could not be built on Solaris 10 and earlier with the
       ngx_http_v3_module.

    *) Bugfixes in HTTP/3.
