Wink

Fixed

• Element index columns (status, traffic %, variant count) rendered blank or raw. The overridden method was renamed from tableAttributeHtml() to attributeHtml() for Craft 5, which had silently disabled it.
• Winner determination could declare a significantly worse variant the winner. The two-proportion z-test is two-tailed, so significance alone doesn't imply improvement — a variant must now actually beat the control to win.
• Visitor IDs were unstable within a single request. Each call to getVisitorId() re-read the request cookie and minted a fresh UUID, scattering one visitor's assignments and impressions across throwaway IDs whenever a page contained more than one experiment. The ID is now memoized per request.
• Conversion goals are returned in a stable, author-defined order instead of alphabetically. This also fixes the wrong goal being deleted when goals were re-saved.

Added

• Codeception integration test suite running against Craft's test framework (element CRUD, queries, services, tracking, report generation, Twig rendering), plus expanded PHPUnit unit coverage (enums, the {% experiment %} tag compiler, PSR-4 layout). Includes a DDEV environment and ddev test runner.

Changed

• Moved VariantReport into its own file (src/models/VariantReport.php) to comply with PSR-4; previously it was only loadable as a side effect of loading ExperimentReport.

Fixed

• Fatal ParseError in ExperimentsController and SettingsController caused by an unescaped apostrophe in the "Couldn't save…" error messages, which prevented the plugin from loading.

Fixed

• PHP 8.4 compatibility: Experiment::defineSources() and defineActions() now declare their parameters as explicitly nullable (?string), resolving an implicit-nullable deprecation that becomes a fatal error in PHP 9.0.

Added

• PHPUnit unit test suite covering the statistical engine (two-proportion z-test, Wilson score interval) and deterministic variant assignment.

Changed

• Plugin schema version aligned to 5.0.0.

Added

• Initial release of Wink for Craft CMS 5.
• Experiments as a custom Craft element type with full index and CRUD.
• Variants with weighted traffic allocation.
• Conversion goals (pageview, click, form submit, custom event).
• Server-side deterministic variant assignment (no flicker).
• Frontend JavaScript tracker with event batching.
• Statistical significance via two-proportion z-test.
• Wilson score confidence intervals.
• Automatic winner determination.
• CP reports with Chart.js visualizations.
• Twig functions: winkVariant(), winkExperiment(), winkTrackingScript().
• {% experiment %} block tag for inline variant content.
• {{ craft.wink.* }} template variable.
• Optional GA4/GTM event forwarding.
• Do Not Track respect.
• IP anonymization option.
• Event retention management.
