+### 2.2.0 (2020-12-14)
+
+  * Added JSON_PARTIAL_OUTPUT_ON_ERROR to default json encoding flags, to avoid dropping entire context data or even records due to an invalid subset of it somewhere
+  * Added setDateFormat to NormalizerFormatter (and Line/Json formatters by extension) to allow changing this after object creation
+  * Added RedisPubSubHandler to log records to a Redis channel using PUBLISH
+  * Added support for Elastica 7, and deprecated the $type argument of ElasticaFormatter which is not in use anymore as of Elastica 7
+  * Added support for millisecond write timeouts in SocketHandler, you can now pass floats to setWritingTimeout, e.g. 0.2 is 200ms
+  * Added support for unix sockets in SyslogUdpHandler (set $port to 0 to make the $host a unix socket)
+  * Added handleBatch support for TelegramBotHandler
+  * Added RFC5424e extended date format including milliseconds to SyslogUdpHandler
+  * Added support for configuring handlers with numeric level values in strings (coming from e.g. env vars)
+  * Fixed Wildfire/FirePHP/ChromePHP handling of unicode characters
+  * Fixed PHP 8 issues in SyslogUdpHandler
+  * Fixed internal type error when mbstring is missing
