Nginx 主线版 1.15.4 已发布，该版本新增了一项特性 —— "ssl_early_data"指令现已可以与 OpenSSL 一起使用。此外还包括一些其他的变更和 bug 修复。Nginx（发音同 engine x）是一款轻量级的 Web 服务器/反向代理服务器及电子邮件（IMAP/POP3）代理服务器，并在一个 BSD-like 协议下发行，可以在 UNIX、GNU/Linux、BSD、Mac OS X、Solaris，以及 Microsoft Windows 等操作系统中运行。
Feature: now the "ssl_early_data" directive can be used with OpenSSL.
Bugfix: in the ngx_http_uwsgi_module.
Bugfix: connections with some gRPC backends might not be cached when using the "keepalive" directive.
Bugfix: a socket leak might occur when using the "error_page" directive to redirect early request processing errors, notably errors with code 400.
Bugfix: the "return" directive did not change the response code when returning errors if the request was redirected by the "error_page" directive.
Bugfix: standard error pages and responses of the ngx_http_autoindex_module module used the "bgcolor" attribute, and might be displayed incorrectly when using custom color settings in browsers.
Change: the logging level of the "no suitable key share" and "no suitable signature algorithm" SSL errors has been lowered from "crit" to "info".
