This update has many changes, please consider whether to upgrade as appropriate, be sure to take a snapshot backup before upgrading.
zstd compression will only be enabled by default if you uninstall and reinstall nginx. If you choose to upgrade directly, please manually add the relevant configuration.
ktls, ngx_http_security_headers_module, and ngx_http_trim_filter_module are not enabled by default. You can enable them yourself if needed.
Post-quantum algorithms require no additional configuration—they will take effect automatically when using an ECC certificate + TLS 1.3 + a supported browser.
OpenResty has not officially released 1.27.5.1. This version is a forked version maintained by ourselves, and does not represent the official OpenResty.
