3. changelog is the usual changelog

Code Review

This pull request introduces a comprehensive announcements feature, covering changelogs, new features, and general notices. The implementation is well-structured across both the backend and the mobile app, with clear separation of concerns. My review focuses on improving the robustness of the API client by ensuring proper URL encoding for all request parameters and completing the implementation of URL handling for call-to-action buttons in the UI, ensuring consistency with user expectations. These changes will prevent potential bugs and ensure the feature works as expected.

The query parameters version and deviceModel are not URL-encoded. This can lead to issues if they contain special characters (e.g., a + in a version string like 1.0.0+123 would be misinterpreted as a space). It's safer to use Uri.encodeComponent for all query parameter values, or construct the URI using its constructor with a queryParameters map to handle encoding automatically and robustly.

Suggested change

	var url = "${Env.apiBaseUrl}v1/announcements/features?version=$version&version_type=$versionType";
	if (deviceModel != null) {
	url += "&device_model=$deviceModel";
	}
	final queryParameters = {
	'version': version,
	'version_type': versionType,
	if (deviceModel != null) 'device_model': deviceModel,
	};
	final url = Uri.parse('${Env.apiBaseUrl}v1/announcements/features').replace(queryParameters: queryParameters).toString();

The exclude_ids query parameter is not URL-encoded. While IDs are often URL-safe, it's best practice to encode all query parameter values to prevent potential issues if they ever contain special characters.

Suggested change

	url += "?exclude_ids=${excludeIds.join(',')}";
	url += "?exclude_ids=${Uri.encodeComponent(excludeIds.join(','))}";
