@@ -41,6 +41,14 @@ New deprecations:
   value equal to what `Logger::WARNING` was giving you.
 - `Logger::getLevelName()` is now deprecated.
 
+### 2.7.0 (2022-06-09)
+
+  * Added `$datetime` parameter to `Logger::addRecord` as low level API to allow logging into the past or future (#1682)
+  * Added `Logger::useLoggingLoopDetection` to allow disabling cyclic logging detection in concurrent frameworks (#1681)
+  * Fixed handling of fatal errors if callPrevious is disabled in ErrorHandler (#1670)
+  * Marked the reusable `Monolog\Test\TestCase` class as `@internal` to make sure PHPStorm does not show it above PHPUnit, you may still use it to test your own handlers/etc though (#1677)
+  * Fixed RotatingFileHandler issue when the date format contained slashes (#1671)
+
 ### 2.6.0 (2022-05-10)
 
   * Deprecated `SwiftMailerHandler`, use `SymfonyMailerHandler` instead
