 We seek to increase clarity at all levels of the update and releases process. Starting with `2.0.0` we will require pull requests adhere to the [Conventional Commits](https://conventionalcommits.org/) spec, which can be summarized as follows:
 
-* Commits that would result in a semver **major** bump must start with `BREAKING CHANGE:`.
+* Commits that would result in a semver **major** bump must start their body with `BREAKING CHANGE:`.
 * Commits that would result in a semver **minor** bump must start with `feat:`.
 * Commits that would result in a semver **patch** bump must start with `fix:`.
 
 * We allow squashing of commits, provided that the squashed message adheres the the above message format.
-* It is acceptable for some commits in a pull request to not include a semantic prefix, as long as a later commit in the same pull request contains a meaningful encompassing semantic message.
