Changes:
```
Changes with nginx 1.29.1 13 Aug 2025
*) Security: processing of a specially crafted login/password when using
the "none" authentication method in the ngx_mail_smtp_module might
cause worker process memory disclosure to the authentication server
(CVE-2025-53859).
*) Change: now TLSv1.3 certificate compression is disabled by default.
*) Feature: the "ssl_certificate_compression" directive.
*) Feature: support for 0-RTT in QUIC when using OpenSSL 3.5.1 or newer.
*) Bugfix: the 103 response might be buffered when using HTTP/2 and the
"early_hints" directive.
*) Bugfix: in handling "Host" and ":authority" header lines with equal
values when using HTTP/2; the bug had appeared in 1.17.9.
*) Bugfix: in handling "Host" header lines with a port when using
HTTP/3.
*) Bugfix: nginx could not be built on NetBSD 10.0.
*) Bugfix: in the "none" parameter of the "smtp_auth" directive.
Changes with nginx 1.29.0 24 Jun 2025
*) Feature: support for response code 103 from proxy and gRPC backends;
the "early_hints" directive.
*) Feature: loading of secret keys from hardware tokens with OpenSSL
provider.
*) Feature: support for the "so_keepalive" parameter of the "listen"
directive on macOS.
*) Change: the logging level of SSL errors in a QUIC handshake has been
changed from "error" to "crit" for critical errors, and to "info" for
the rest; the logging level of unsupported QUIC transport parameters
has been lowered from "info" to "debug".
*) Change: the native nginx/Windows binary release is now built using
Windows SDK 10.
*) Bugfix: nginx could not be built by gcc 15 if ngx_http_v2_module or
ngx_http_v3_module modules were used.

optimization if ngx_http_v3_module was used.

Continuous Integration and Distribution
Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 24.11 release
- Tests for unstable/master
- Tests for the NixOS 24.11 release
Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.
