= 4.3.1 =
* Tested up to WordPress 7.1.
* Feature: Welcome modal on first activation shows local image and video processing availability, site-level missing capability chips (formats no local processor can provide), and a subtle CDN/cloud upsell when unlicensed.
* Feature: Once-ever review prompt on Overview after meaningful savings (distinct optimized attachments and bandwidth saved), with WordPress.org review and support links; suppressed while welcome is showing or optimizations have failed. Force-open with `flux_show_review=1` for testing. Dialog uses BrandIcon, inline savings Chip, solopreneur copy, and close control.
* Feature: Need help links on Overview failed-optimizations notice and attachment details error alerts.
* Deprecated: VideoConverter::get_conversion_stats() stub; use ConversionTracker for live conversion statistics.

= 4.3.0 =
* Feature: Local HEIC/HEIF conversion with Imagick decode (libheif 1.18.2+ recommended for modern iOS photos), optional animated HEIF-to-WebP via FFmpeg, and separate HEIC capability reporting.
* Feature: Unified Action Scheduler retries for local and cloud failures (3 automatic attempts with progressive backoff), with processing routed by current license/settings and Flux logging on failures.
* Feature: Redesigned attachment details panel with async REST loading, compact skeleton placeholder, MUI Grid responsive layout that stays within the WordPress container, size accordion, format URLs, and a license-aware CDN upsell.
* Feature: Attachment details poll every 15 seconds while Pending (including locally deferred video conversions) and refresh Convert/Disable/Enable actions in place without a full page reload.
* Feature: Attachment details show only formats enabled and supported by the active media converter (WebP/AVIF for images, AV1/WebM for videos), with per-size savings badges compared to the same-size original.
* Feature: Attachment details and conversion controls use WordPress `edit_post` attachment capabilities.
* Fix: External processing activation requires a valid license (`is_external_processing_active`); uninstall removes the correct option keys while preserving shared suite account ID; safer database table-drop SQL; external operations builder hardening.
* Fix: Image conversion commits files and metadata/statistics together; skipped retry dispatches no longer consume the retry budget; plugin and common external API URL/timeout constants stay aligned before shared client init.

= 4.2.0 =
* Feature: Media Library shows optimization status and filter options (Optimized, Pending, Failed, Disabled, Unprocessed). Conversion stats API now reports failed external job counts. New constants added: FLUX_MEDIA_OPTIMIZER_STALE_JOB_THRESHOLD, FLUX_MEDIA_OPTIMIZER_FAILED_JOB_RETRY_LIMIT, FLUX_MEDIA_OPTIMIZER_CLEANUP_BATCH_SIZE.
* Feature: Daily cleanup cron recovers stale external jobs, automatically retries failed jobs with a set limit, and cleans expired admin notices.

= 4.1.6 =
* Security: Harden external webhook endpoint (account ID verification in permission_callback, job-state checks, CDN host allowlist, rate limiting).
* Security: Register webhook route only when external service is enabled and license is valid.
* Fix: Remove duplicate admin AJAX handler registration for attachment actions.
* Security: Avoid exposing raw exception messages in plugin REST error responses.
* Removed legacy plugin logs REST API and `flux_media_optimizer_logs` table creation; logging uses flux-plugins-common (`flux_plugins_logs` + `flux-plugins-common/v1/logs`).
