Some examples:
### Breaking Changes
If your commit introduces a change that breaks backward compatibility (e.g. removes or
renames a public API, changes a function signature, or alters existing behavior in a
way that requires callers to update their code), it must be flagged the following ways:
**1. Add `!` after the scope in the subject line** to make the breaking change immediately
visible in the commit history:
```text
feat(drm)!: replace lv_drm_init() arguments
```
**2. Add a `BREAKING CHANGE` entry in the footer** to describe what changed and how to
migrate:
```text
feat(drm)!: replace lv_drm_init() arguments
The card and connector arguments have been merged into a single
device path string for consistency with other driver APIs.
BREAKING CHANGE: lv_drm_init(card, connector) is now
lv_drm_init(device). Replace calls like lv_drm_init(0, 1) with
lv_drm_init("/dev/dri/card0").
```
Using both `!` and `BREAKING CHANGE` together is recommended for maximum clarity,
the `!` signals at a glance that the commit is breaking, while the footer explains
exactly what callers need to update.
