What I have done

• Completed multi-category support for com_newsfeeds, including backend integration, saving/loading secondary categories, and category filtering.

• Implemented custom fields support for the API in both com_content (articles) and com_contact, ensuring fields assigned to secondary categories load and save correctly.

• Resolved API PATCH request behaviors to safely preserve existing tags when payloads are sent without a tags property.

• Continued extensive testing using Cypress integration test suites across the updated components.

Problems

• Handled edge cases regarding field mappings and data structures when processing nested API inputs for custom fields.

• Ensured consistent tag preservation during partial updates to maintain parity with core Joomla standards.

Plans for the remaining coding period

• Complete multi-category support and custom fields handling for the API in com_newsfeeds and com_banners.
