File	Description
projects/packages/forms/src/contact-form/class-contact-form.php	Added aria-live attribute to submission confirmation div for accessibility
projects/plugins/jetpack/changelog/update-forms-submit-aria-live	Added changelog entry for the Jetpack plugin
projects/packages/forms/changelog/update-forms-submit-aria-live	Added changelog entry for the Forms package

The changelog entry has an extra quotation mark at the end. It should end with a period only, not a period followed by a quotation mark.

Suggested change

	Help assistive technology users notice submission confirmation."
	Help assistive technology users notice submission confirmation.

[Copilot]

The changelog type should be consistent across both changelog entries. The plugin changelog uses "enhancement" while the package changelog uses "added". Since this is an improvement to existing functionality rather than entirely new functionality, "enhancement" is more appropriate and consistent.

That could be good or bad, depending on the situation. Everything covered before, and still is? Great! Nothing was covered before? Not so great. 🤷
