@@ -11,11 +11,13 @@ All notable changes to `error-stack` will be documented in this file.
 ### Features
 
 - Report has been split into `Report<C>` and `Report<[C]>` to distinguish between a group of related errors and a single error. These errors can still be nested.
+- Introduce a new `unstable` flag, which is used to enable unstable features, these features are not covered by semver and may be modified or removed at any time.
 
 ### Breaking Changes
 
 - `Extend` is no longer implemented by `Report<C>`, instead it is implemented on `Report<[C]>`, either use `From` or `Report::expand` to convert between `Report<C>` into `Report<[C]>`.
 - `extend_one` has been renamed to `push` and is only implemented on `Report<[C]>`.
+- `bail!(report,)` has been removed, one must now use `bail!(report)`. This is in preparation for the unstable `bail!` macro that allows to construct `Report<[C]>`.
