Note

Currently, we do not run e2e tests as a check on opencrvs-countryconfig-repo PRs. Please ensure your PR doesn't break any e2e tests.

One method for doing this is to open a PR with these changes to opencrvs-farajaland as well, and see if the PR check passes there.

Oops! Looks like you forgot to update the changelog. When updating CHANGELOG.md, please consider the following:

• Changelog is read by country implementors who might not always be familiar with all technical details of OpenCRVS. Keep language high-level, user friendly and avoid technical references to internals.
• Answer "What's new?", "Why was the change made?" and "Why should I care?" for each change.
• If it's a breaking change, include a migration guide answering "What do I need to do to upgrade?".
