@ajarmoniuk please let me know when I can do release.
Do you want add something more?

[jarmoniuk]

I've just begun working on #213, but I think it could take a couple of days (one or two).

[jarmoniuk]

I'm almost done with #231 which I consider a bug (I don't think it was intentional to allow downgrading), but I've added a feature to allow it and fixed the behaviour somehow (it did not work at all for ranges). -> #662

[slawekjaranowski]

I'm very glad to next release, we have many bug fixes and improvements.

Of course I want not to wait to resolve all opened issues.

So next release will be at 5 of September.
Unless you discover some of critical issue.

Big thanks to @ajarmoniuk

[slawekjaranowski]

Done.
