- Fixed use of unnecessary cache for API key validation.
- It's all new!
- Cache API key validation result so viewing plugin settings doesn't fire a live sandbox request on every page load.
- Add an explicit request timeout to the QuickEmailVerification API call so a slow/unreachable API can't stall form submission indefinitely.
- Add PHPCS, PHPStan, and PHPUnit tooling, CI workflow, and an uninstall handler for Labs compliance.
- Add missing plugin headers (Requires at least, Requires PHP, Requires Plugins) and a translations POT file.
