+- Updated to 1.23.1
+  * Feature: memory usage optimization in configurations with SSL proxying.
+  * Feature: looking up of IPv4 addresses while resolving now can be
+    disabled with the "ipv4=off" parameter of the "resolver" directive.
+  * Change: the logging level of the "bad key share", "bad extension",
+    "bad cipher", and "bad ecpoint" SSL errors has been lowered from "crit" to "info".
+  * Bugfix: while returning byte ranges nginx did not remove the
+    "Content-Range" header line if it was present in the original backend response.
+  * Bugfix: a proxied response might be truncated during reconfiguration
+    on Linux; the bug had appeared in 1.17.5.
