vendor/github.com/sirupsen/logrus/CHANGELOG.md

+# 1.1.0
+This new release introduces:
+  * several fixes:
+    * a fix for a race condition on entry formatting
+    * proper cleanup of previously used entries before putting them back in the pool
+    * the extra new line at the end of message in text formatter has been removed
+  * a new global public API to check if a level is activated: IsLevelEnabled
+  * the following methods have been added to the Logger object
+    * IsLevelEnabled
+    * SetFormatter
+    * SetOutput
+    * ReplaceHooks
+  * introduction of go module
+  * an indent configuration for the json formatter
+  * output colour support for windows
+  * the field sort function is now configurable for text formatter
+  * the CLICOLOR and CLICOLOR\_FORCE environment variable support in text formater
+
+# 1.0.6
+
+This new release introduces:
+  * a new api WithTime which allows to easily force the time of the log entry
+    which is mostly useful for logger wrapper
+  * a fix reverting the immutability of the entry given as parameter to the hooks
+    a new configuration field of the json formatter in order to put all the fields
+    in a nested dictionnary
+  * a new SetOutput method in the Logger
+  * a new configuration of the textformatter to configure the name of the default keys
+  * a new configuration of the text formatter to disable the level truncation
+
 # 1.0.5
 
 * Fix hooks race (#707)
