Changes with Angie 1.4.0 12 Dec 2023
*) Feature: support for establishing HTTP/3 connections to upstream
servers in the HTTP proxy module while allowing clients to use
arbitrary HTTP versions. Configuration is done with the
"proxy_http_version" directive and a set of "proxy_quic_" and
"proxy_http3_" directives.
*) Feature: a mechanism for smoothly bringing the proxied server online
after a failure using the "slow_start" option of the "server"
directive in the "upstream" block.
*) Feature: "mqtt_preread" directive in the "stream" module, which
allows extracting the username and client id from the CONNECT packet
of the MQTT protocol into the $mqtt_preread_username and
$mqtt_preread_clientid variables.
*) Feature: limiting the response rate of MP4 files transmission to the
client proportionally to the bitrate using the "mp4_limit_rate" and
"mp4_limit_rate_after" directives, which reduces the bandwidth load.
*) Feature: all functionality of nginx 1.25.3.
*) Bugfix: if a proxied server was the only one in a group, it could be
incorrectly reported as "unavailable" in the statistics API even
after recovery.
Changes with Angie 1.3.2 23 Nov 2023
*) Bugfix: possible incorrect values of metrics in Prometheus output
that used variables other than $p8s_value for their values; in
practice the issue could occur with
"angie_http_upstreams_peers_state" and
"angie_stream_upstreams_peers_state" from the standard
"prometheus_all.conf" template.
*) Bugfix: some connection attempts to upstream servers might not have
been properly accounted for in the statistics API if they failed
immediately; the bug had appeared in 1.3.0.
Changes with Angie 1.3.1 18 Oct 2023
*) Security: added extra limitations to HTTP/2 stream handling for
better protection against the DoS attack known as "HTTP/2 Rapid
Reset" (CVE-2023-44487).
Changes with Angie 1.3.0 19 Sep 2023
*) Feature: ability to specify multiple match patterns in the "location"
directive, which allows to combine several "location" blocks with
similar settings and therefore simplify configuration by reducing
duplication.
*) Feature: export of varied statistics metrics in Prometheus format
with flexible template configuration using the new "prometheus" and
"prometheus_template" directives.
*) Feature: detailed information and metrics for groups of stream
upstream servers in the statistics interface provided by the "api"
directive.
*) Feature: the "resolve" option of the "server" directive in the
"stream" module’s "upstream" block that allows to monitor changes to
the list of IP addresses corresponding to a domain name, and
automatically update it without the need of reloading configuration.
*) Feature: the "service" option of the "server" directive in the
"stream" module’s "upstream" block that allows to retrieve lists of
addresses from DNS SRV records, with basic priority support.
*) Feature: access to the contents of configuration files used by the
current generation of worker processes via the interface provided by
the "api" directive with the "api_config_files" directive enabled.
*) Feature: display of the configuration generation number in process
titles, which allows to monitor the success of configuration reloads
and the number of previous worker process generations using the "ps"
utility.
*) Feature: all functionality of nginx 1.25.2.
*) Bugfix: compilation failed when ./configure options
"--without-http_upstream_zone_module" or
"--without-stream_upstream_zone_module" were used; the bug had
appeared in 1.2.0.
*) Change: now appname "angie" is used when loading the OpenSSL
configuration.
Changes with Angie 1.2.0 30 May 2023
*) Feature: the "sticky" directive and related options in the HTTP
module "upstream" block, that allow to configure sticky sessions
mode, where all requests of the session are routed to the same
server.
*) Feature: the $upstream_sticky_status variable, that takes either
"NEW", "HIT" or "MISS" values depending on success of requesting
related upstream server with sticky sessions enabled.
*) Feature: support for NTLS in the HTTP and stream modules using
TongSuo TLS library, that can be enabled via the "--with-ntls" build
time option and configured with the "ssl_ntls" and "proxy_ssl_ntls"
corresponding directives.
*) Feature: in the HTTP and stream proxy-modules ability to specify
multiple certificates with different types (RSA and ECDSA) and
corresponding keys, using the "proxy_ssl_certificate" and
"proxy_ssl_certificate_key" directives.
*) Feature: display of version and build name in the "master" process
title, which allows to get this information about a running server
instance using the "ps" utility.
*) Feature: ability to compress of "207 Multi-Status" responses by the
gzip module. Thanks to DBotThePony.
*) Feature: all functionality of nginx 1.25.0, including HTTP/3 support.
Changes with Angie 1.1.0 24 Jan 2023
*) Feature: the "resolve" option of the "server" directive in the HTTP
module "upstream" block, that allows to monitor changes to the list
of IP addresses corresponding to a domain name, and automatically
update it without the need of reloading configuration.
*) Feature: the "service" option of the "server" directive in the HTTP
module "upstream" block, that allows to retrieve lists of addresses
from DNS SRV records, with basic priority support.
*) Feature: detailed information and metrics for the groups of HTTP
upstream servers in the statistics interface provided by the "api"
directive.
*) Feature: autoindex uses natural sorting order for directory listings.
*) Feature: all functionality of nginx 1.23.3.
*) Bugfix: compilation failed due to false warning when using GCC 9 or
older with the -O2 or higher optimization.
Changes with Angie 1.0.0 27 Oct 2022
*) Feature: the "api" directive, that provides HTTP RESTful interface
for accessing in JSON format basic information about a web server
instance, as well as metrics of client connections, shared memory
zones, DNS queries, HTTP requests, HTTP responses cache, TCP/UDP
sessions of "stream" module, and zones of "limit_conn/limit_req"
modules.
*) Feature: the "status_zone" directive in "http" module for specifying
zone to collect request metrics in "server" and "location" contexts.
*) Feature: the "status_zone" directive in "stream" module for
specifying zone to collect TCP/UDP session metrics.
*) Feature: the "status_zone" parameter of the "resolver" directive for
specifying zone to collect metrics on DNS queries.
*) Feature: the $angie_version variable with version of Angie.
*) Feature: all functionality of nginx 1.23.2.
