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。Nginx 主线版 1.15.3 已发布，在该版本中，TLSv1.3 现在可以与 BoringSSL 一起使用，此外还包括一些其他的新增功能和 bug 修复。

• Feature: now TLSv1.3 can be used with BoringSSL.

• Feature: the "ssl_early_data" directive, currently available with BoringSSL.

• Feature: the "keepalive_timeout" and "keepalive_requests" directives in the "upstream" block.

• Bugfix: the ngx_http_dav_module did not truncate destination file when copying a file over an existing one with the COPY method.

• Bugfix: the ngx_http_dav_module used zero access rights on the destination file and did not preserve file modification time when moving a file between different file systems with the MOVE method.

• Bugfix: the ngx_http_dav_module used default access rights when copying a file with the COPY method.

• Workaround: some clients might not work when using HTTP/2; the bug had appeared in 1.13.5.

• Bugfix: nginx could not be built with LibreSSL 2.8.0.
