*) Security: a buffer overflow might occur while handling a COPY or MOVE request in a location with "alias", allowing an attacker to modify the source or destination path outside of the document root (CVE-2026-27654).
Thanks to Calif.io in collaboration with Claude and Anthropic Research.

*) Security: processing of a specially crafted mp4 file by the ngx_http_mp4_module on 32-bit platforms might cause a worker process crash, or might have potential other impact (CVE-2026-27784).
Thanks to Prabhav Srinath (sprabhav7).

*) Security: processing of a specially crafted mp4 file by the ngx_http_mp4_module might cause a worker process crash, or might have potential other impact (CVE-2026-32647).
Thanks to Xint Code and Pavel Kohout (Aisle Research).

Thanks to Asim Viladi Oglu Manizada, Colin Warren, Xiao Liu (Yunnan University), Yuan Tan (UC Riverside), and Bird Liu (Lanzhou University).

*) Feature: the "multipath" parameter of the "listen" directive.

*) Feature: the "local" parameter of the "keepalive" directive in the "upstream" block.

*) Change: now the "keepalive" directive in the "upstream" block is enabled by default.

*) Change: now ngx_http_proxy_module supports keepalive by default; the default value for "proxy_http_version" is "1.1"; the "Connection" proxy header is not sent by default anymore.

*) Bugfix: an invalid HTTP/2 request might be sent after switching to the next upstream if buffered body was used in the ngx_http_grpc_module.
