Next release 1.7.0

[NickNaso]

Hi everyone,
it's my intention create a new release. The last release is 1.6.3 and was deployed the 3rd April. Now we have some new APIs and important fixes to release. Here I report what we need to create this new release:

• Merge this PR doc: add ThreadSafeFunction to main README #513
• Merge this PR AsyncWorker: add GetResult() method #512

If anyone have some other things that needs to be done please add them in the list above.

I'd suggest we wait for #512 otherwise I agree its a good time for a new release.

I’m starting to create the new release.

I'm closing the issue because the release has been published.
