features continues (only changes related to fixing serious bugs and vulnerabilities are made in the parallel stable branch 1.20).     <\/p>\n<p>Key Changes:  <\/p>\n<ul>\n<li class=\"l\"> Support for establishing HTTP\/2 connections using the NPN (Next Protocol Negotiation) extension instead of ALPN has been discontinued;\n<li class=\"l\"> Closure is ensured <a class=\"wpil_keyword_link\"

client if a supported protocol is not selected during the connection negotiation;\n<li class=\"l\"> In the directive 'sendfile_max_chunk', the default value has been changed to 2 megabytes;\n<li class=\"l\"> The stream module has added the proxy_half_close directive, which allows configuring behavior when closing a proxied TCP connection on one side ('TCP half-close');\n<li class=\"l\"> In the stream module, the 'ssl_alpn' directive has been added to define the list of supported ALPN protocols (h2, http\/1.1) and the variable $ssl_alpn_protocol, reflecting the protocol agreed upon with the client ALPN;\n<li class=\"l\"> Support for calling SSL_sendfile() when using OpenSSL 3.0 has been added;\n<li class=\"l\"> The 'mp4_start_key_frame' directive has been added to the ngx_http_mp4_module for streaming video starting from a key frame.\n<li class=\"l\"> The $content_length variable has been fixed when using chunked transfer encoding;\n<li class=\"l\"> Fixed a connection caching bug when receiving a response of incorrect length from the proxied backend;\n<li class=\"l\"> Logging has been corrected to the 'error' level instead of 'info' for incorrect headers from backends;\n<li class=\"l\"> Fixed request hanging issues when using HTTP\/2 and the aio_write directive.    <\/ul>\n<p>Source: <a content=\"nofollow\" rel=\"nofollow\"
