Incomplete CHANGELOG

[szikszail]

Could you please list the breaking changes in the formatter which are mentioned in CHANGELOG?

Custom formatters: Formatter helpers and EventDataCollector had breaking changes to support retry

Currently, it is really hard to figure out what changed and what must be changed to support Cucumber 6 if we create a custom formatter. E.g. getTestCaseData has been removed and it is not clear, how getTestCaseAttempt would replace it, or what other function does.

At the same time the link to EventDataCollector in the documentation is not valid.

Sorry, yes the custom formatters have never been documented all that well.

Note there are a lot of unreleased changes in master right now so I suggest looking at documentation via the tag of the release you are using: https://github.com/cucumber/cucumber-js/blob/v6.0.5/src/formatter/helpers/event_data_collector.js (then the link should work)

I think we can work on some better formatter documentation in Cucumber 7 (which will include the move to typescript and the use of a new internal structure for messages)
