# Breaking Changes

> When backwards-incompatible changes are made to the API, we release a new, dated version. Here is the list of changes we consider breaking.

<Warning>
  Some changes that we do not consider "breaking" might nonetheless break your code.

  For example: adding a new enum value to an existing property is not considered breaking, but your parser may break depending on implementation.
