Meaningful versioning

[docktermj]

I appreciate that you are versioning according to year-month-day (YYYY-MM-DD), However it doesn't tell me anything important about importing a version of the s3fs into a python program. For instance 0.4.2 worked, but 2021.08.01 broke do to dependency conflicts. (Ref: #528)

The question is: When did the backward breaking change occur?

Many folks use Semantic Versioning (https://semver.org/) to communicate breakage, new features, and patches.

I hope you'll consider Semantic Versioning in the future.

We decided, along with other dask projects, that we could not faithfully maintain semantic versioning - given the large API and backends supported, there would, generally, always be some part of the code-base that could be considered not backward compatible on every release. fsspec is strange as a package, being both an end-user library (with a fairly stable API) and many internal details which other packages depend on in detail.

@martindurant I do thank you for considering Semantic Versioning.
