@vitek-rostislav Ready to review, I'll rebase this and retarget to master after merge of #554

Hi @TomasVotruba, thank you for the PR. annotations for the win 😄 It looks fine, however, there is one issue that needs to be addressed, please check it out.

One more thing, do you think we should update the upgrading instructions? From a project point of view, if I wanted to start using the new version, I might break my build for example as it might fail on the new standards. So I think we should probably add instruction to run php phing standards-fix to let the fixers do their work 🙂

Well, I'd just add 1 line to CHANGELOG.md, that all.

Well, you should always:

• rebase on master
• fix cs
• push

So there is no need to create extra notes.
