I am new to the add-on development I don't know what are the practices.

I thought to add release notes when I have some relevant information for the users. But if you need release notes in any case then I will do that for the future. I added the release notes for the current version as "Minor code optimizations".

Can I ask you how is the license relevant to you as an end user? I see that the license may be relevant to another developer/distributor who wants to use parts of the code.
