April 2026 — woocommerce/woocommerce Key features delivered: - AddressAutocomplete enhancement: three-layer detection to distinguish user input from browser autofill, reducing unnecessary API calls and double-autocomplete scenarios; cross-browser tests added. - SlotFill components rendering tests and consumer blocks coverage: added unit tests for all public SlotFill components and consumer blocks to ensure correct rendering and prop forwarding. - Locale/address form stability: fixes to ensure locale-based field visibility doesn't break address forms when country/state are hidden; preserves base country for locale resolution and includes end-to-end validation. - Emoji handling in Cart/Checkout blocks: removed WordPress emoji detection script to prevent DOM corruption during React hydration and ensuing crashes. Major bugs fixed: - Stale pending delete state handling for bundled products in cart: ensure child items are cleared from pending delete when a parent is removed, fixing shipping and totals calculations. - Locale/address form stability when fields hidden: prevents locale filter issues from hiding country/state incorrectly; ensures country remains visible and required for locale resolution. - Other quality improvements: lint/test fixes, changelog automation, and test utility updates (CI compatibility). Overall impact and accomplishments: - Improved checkout reliability and shipping accuracy, reducing user confusion and post-purchase friction. - Significantly expanded QA coverage and test reliability through SlotFill tests and cross-browser validations. - Reduced API noise from address autofill and stabilized frontend rendering by removing emoji-based DOM mutations, increasing resilience during hydration. - Streamlined release hygiene with automated changelog updates and test utilities, enabling faster iteration and safer deployments. Technologies/skills demonstrated: - React/JSX, Jest unit tests, and cross-browser end-to-end tests (e.g., Playwright) for robust UI validation. - Linting, test mocks, and CI automation to improve code quality and test reliability. - Change management and documentation via automated changelog entries and changelog-driven release notes.
