 Changes for Test::Nginx
 
+0.27 - 2020-07-02
+
+ *   feature: added the --- reload_fails new section to skip checking
+     config_version after HUP reload in the HUp reload testing mode.
+
+ *   feature: added a "--- gen_dgram_request" section.
+
+ *   feature: relaxed the Server response header parsing pattern for
+     extracting the nginx core verison number.
+
+ *   bugfix: when --- reload_fails is specified, we did not assume ---
+     no_chck_leak since it would always fail in the check leak testing mode.
+
+ *   feature: implemented the `--- shutdown_error_log` section for
+     checking the error logs generated during nginx exit.
+
+ *   feature: added new test mode enabled by the env TEST_NGINX_USE_HTTP2=1
+     and new section "--- http2", for enabling the HTTP/2 protocol to
+     send the test request.
+
+ *   bugfix: when TEST_NGINX_USE_STAP=1 env was specified, the master process
+     would be turned off when for test blocks without actually using --- stap.
+
+ *   feature: be more patient to wait for the nginx to start up in profiling
+     and "check leak" test mode.
+
+ *   optimize: use perl's own remove_tree() instead of the shell command
+     'rm  -rf' since the latter may use too much memory.
+
+ *   feature: added support for the env TEST_NGINX_CHECK_LEAK_COUNT to control
+     how many data points to sample in the "check leak" test mode.
+
+ *   feature: now we pass through the MOCKNOEAGAIN_VERBOSE and MOCKNOEAGAIN
+     env to the nginx worker processes by default as well.
+
+ *   feature: added support for TEST_NGINX_WORKER_USER env for setting the user
+     account (and user group) for nginx worker processes; defaults to root when
+     the master is run by root.
+
+ *   bugfix: the value of env TEST_NGINX_WORKER_USER did not accept a single
+     user name (without a user group name).
+
+ *   feature: added support for the --- access_log section for checking access
+     log file content.
+
+ *   bugfix: valgrind test mode: we no longer disable nginx master process in
+     this mode.
+
+ *   bugfix: we did not clean up nginx's *_cache directories under the server
+     root directory.
+
+ *   feature: added support for environment variable TEST_NGINX_REUSE_PORT for
+     enabling the reuseport parameter in the listen directive automatically
+     generated in nginx.conf.
+
+ *   feature: we now check for the new "write guard" warning message to detect
+     misuses of lua globals.
+
+ *   feature: added the use_hup() Perl utility function.
+
+ *   feature: when --- no_error_log fails, we output up to 9 lines of
+     subsequent error log messages for better debuggability (for example,
+      wen can have complete lua backtraces).
+
+ *   feature: expanded environment values in --- user_files section.
+
+ *   bugfix: when setting TEST_NGINX_USE_HUP=1, some directories could not be
+     cleaned up correctly.
+
+ *   feature: implemented the TEST_NGINX_USE_RR=1 env for enabling Mozilla rr
+     to record the nginx server execution.
+
+ *   bugfix: increased resiliency in HUP reload mode.
+
+ *   feature: added the '--- skip_openssl' section to skip tests depending on
+     the OpenSSL version NGINX was built with.
+
+ *   bugfix: ensured we do not remove some files when using HUP mode.
+
+ *   bugfix: properly use a concat operator instead of a range.
+
+ *   bugfix: ensure servroot is cleaned up when starting NGINX for the first
+     time.
+
 0.26 - 2017-04-09
 
  *   feature: added new Test::Nginx::Socket::Lua::Dgram module for
