 ### v1.2.0 (2025-11-30)
 
-- Added support for setting access control on queue. Ported `AccessControlEntry`, `AccessControlEntryType`, `AccessControlList`, `MessageQueueAccessControlEntry`, `MessageQueuePermission`, `MessageQueuePermissionAccess`, `MessageQueuePermissionEntry`, and `MessageQueuePermissionEntryCollection` classes to provide access control permissions support. (PR #5, contributed by @j0hnth0m)
-- Fixed Unicode string null termination in `StringToBytes` method. This bug affected `MessageQueue.Label`, `MessageQueue.MulticastAddress`, `Message.Label`, `Message.AuthenticationProviderName`, and queue format name properties, causing them not to persist correctly to MSMQ.
+- **Breaking Change**: Changed target framework from `netstandard2.0` to `net8.0`. Since MSMQ is a Windows-only technology, the original cross-platform targeting via .NET Standard was unnecessary. Mono has transitioned to WineHQ, .NET Framework already has native System.Messaging support, and other platforms (Silverlight, UWP, Unity) are not applicable targets for this library.
+- **License Correction**: Changed license from MIT to Ms-RL (Microsoft Reciprocal License) to properly comply with the original Microsoft Reference Source license terms.
+- **Documentation**: Revised terminology throughout the documentation. Replaced "counterfeit" with "unofficial port" to better reflect the legitimate nature of this community-maintained derivative work.
+- **New Feature**: Added support for setting access control on queue. Ported `AccessControlEntry`, `AccessControlEntryType`, `AccessControlList`, `MessageQueueAccessControlEntry`, `MessageQueuePermission`, `MessageQueuePermissionAccess`, `MessageQueuePermissionEntry`, and `MessageQueuePermissionEntryCollection` classes. (PR #5, contributed by @j0hnth0m)
+- **Bug Fix**: Fixed Unicode string null termination in `StringToBytes` method. This bug affected `MessageQueue.Label`, `MessageQueue.MulticastAddress`, `Message.Label`, `Message.AuthenticationProviderName`, and queue format name properties.
 
 ### v1.1.0 (2019-11-06)
 
-Trustee class namespace was moved from System.Messaging to Experimental.System.Messaging. It could break your existing build process.
+- **Breaking Change**: Moved `Trustee` class namespace from `System.Messaging` to `Experimental.System.Messaging`.
 
 ### v1.0.0 (2018-01-06)
 
-This version of the System.Messaging package excludes all advanced features such as code access security, execute permissions, and Active Directory integration. I released the package keeping in mind the minimal use of Message Queuing communication facilities. Please confirm whether it is suitable for actual use through unit test and integration test.
+- **Initial Release**: Ported System.Messaging for .NET Core with minimal feature set. Excludes advanced features such as code access security, execute permissions, and Active Directory integration.
