- When eventually the major will be bumped next week the returned version will become `5.0.0` which changes the `content-length` header in all of the responses using the version from package.json
- The version number is dynamic, so it's expected the content-length to float as minor and patch versions fluctuate in 1-2 digit numbers. For lon-term easy maintenance it's best to set the content-length to any number (or maybe some sort of floating range in the future?)

- this column is not used and I was going to add `validation` to it but
it's better to clean it up and re-add the column if we need it again

- We're getting rid of the concept of api versions inside of Ghost
- Instead of storing the supposed api version a webhook was created with, store the current ghost version
- This way we can determine if anything signicant changes in future and we need to update webhooks or something
- webhooks are one of the remaining places where we need some sort of api version handling
- in order to fixup the tests for this, I wanted to first change them to use the e2e framework
