Missing release notes after 3.0 release

[VadimOvchinnikov]

Documentation Is:

• Missing
• Needed
• Confusing
• Not Sure?

Please Explain in Detail...

There's no changelog for releases 3.1.0 and 3.2.0

Your Proposal for Changes

I suggest to add documentation about new releases (3.1.0 and 3.2.0 as of now).
