Add a changelog

[nirvdrum]

I was recently encountering an issue with fetchPolicy not being a valid option. I tried to work out why that might be by starting with the library changelog, in order to see when it was introduced. Unfortunately, there isn't a changelog for this project.

As it turns out, the option only exists in master and, correspondingly, the README only applies to master.

Hey there! We are indeed thinking in adding one with lerna and conventional commits, we already use this internally and works wonders

Cool. I'm unfamiliar with either of those tools. A simple text file indicating high level changes from release-to-release, along with release dates, would be perfectly fine. If you have a tool that simplifies it, even better.

@fakenickels Thanks for addressing, but where can I find the changelog or release notes? I can't find a file with history information anywhere in the repo and the GitHub releases page has something for 2.0.0-beta.1, but there's been nine tagged releases since then without any indication of what's changed.

We don't have this for old releases, we'll introduce with the new system of packages management
