Publish the 0.5.1

[aknarts]

Hello,

the version 0.5.0 uses tokio 0.2 which is an issue if you want to use a 1.0 version of tokio in your application, this is fixed in the 0.5.1 version(master) but that has sadly not been published yet.

Will be using git version of this till that gets published

Are there any issues which are preventing us from publishing 0.5.1?

I'd rather go with 0.6.0 straight, especially if/when https://github.com/camallo/dkregistry-rs/pull/232 and https://github.com/camallo/dkregistry-rs/pull/224 get merged.

Currently biggest issue is probably deciding on MSRV and fixing tests for PRs

@vrutkovs now I see both merged, any updates? There is plan for 0.6.0?
