PR Summary

• Added a new feature in CHANGELOG.md
  A new debugging tool (feature Split debug #617 by @xepozz) has been added to a module (yiisoft/yii-debug). This tool will help to identify and solve problems more effectively.

• Enhanced two features in CHANGELOG.md
  Both feature Split debug #617 and Minor fix phpdoc and changelog #733 have been refined to improve system annotation related to a specific function (ConnectionInterface::transaction() method) of the software - this was carried out by @xepozz and @vjik. This optimization would offer clearer guidelines to other developers when using this module.

• Update to the transaction() method in the ConnectionInterface.php file
  The "transaction()" function details in the 'ConnectionInterface.php' file have been modified to enhance the code's clarity. This includes additional tags for a parameter ($closure), and adjustment to the function return type (from nonexistent to being able to return various kinds of data). These changes will allow for more flexibility when using the function.
