BC127 melody Software Release

Is it possible to have a document explaining better the difference between Melody V6 and V7?

A lot of commands have been added like BLE_SECURITY and BT_STATE, but there is no mention of these commands in the release notes.

For example, a bug that I reported in this forum thread seems to be fixed in Melody 7, but it is not mentionned in the release notes.

I know the firmware has been released just a couple of days ago, but more information would be greatly appreciated.

Thank you
