+Pull requests that fix bugs and add features that fall in the following categories do not require a **Stable Release Exception** to be granted to be included in a stable point-release:
 
 * **Severe regressions**.
 * Bugs that may cause **client applications** to be **largely unusable**.

 ## What pull requests will NOT be automatically included in stable point-releases
 
 As rule of thumb, the following changes will **NOT** be automatically accepted into stable point-releases:
 
 * **State machine changes**.
-* **Client application's code-breaking changes**, i.e. changes that prevent client applications to *build without modifications* to the client application's source code.

+* **API-breaking changes**, i.e. changes that prevent client applications to *build without modifications* to the client application's source code.
+* **CLI-breaking changes**, i.e. changes that require usage changes for CLI users.
 
  In some circumstances, PRs that don't meet the aforementioned criteria might be raised and asked to be granted a *Stable Release Exception*.
 
 ## Stable Release Exception - Procedure
 
-1. Check that the bug is either fixed or not reproducible in `master`. It is, in general, not appropriate to release bug fixes for stable releases without first testing them in `master`. Please apply the label [0.42 «Stargate»](https://github.com/cosmos/cosmos-sdk/labels/0.42%20LTS%20%28Stargate%29) to the issue.

 2. Add a comment to the issue and ensure it contains the following information (see the bug template below):
 
 * **[Impact]** An explanation of the bug on users and justification for backporting the fix to the stable release.
 * A **[Test Case]** section containing detailed instructions on how to reproduce the bug.
 * A **[Regression Potential]** section with a clear assessment on how regressions are most likely to manifest as a result of the pull request that aims to fix the bug in the target stable release.
 
-3. **Stable Release Managers** will review and discuss the PR. Once *consensus* surrounding the rationale has been reached and the technical review has successfully concluded, the pull request will be merged in the respective point-release target branch (e.g. `release/v0.42.x`) and the PR included in the point-release's respective milestone (e.g. `0.42.5`).
