Changelog

Ultimate Watermark follows semantic versioning loosely — MAJOR.MINOR.PATCH where MAJOR is reserved for breaking compatibility changes (rare).

Ultimate Watermark (free) — 2.0.8

Refactor of the processor layer (Processors/GDWatermarkProcessor.php, Processors/ImagickWatermarkProcessor.php).
Unified rule evaluator (RulesEvaluator.php) replaces legacy watermark_on / watermark_post_types (still falls back to legacy when no unified rules exist).
New conditional rule UI (filter uwm_condition_types).
Originals backup folder pattern: uploads/ulwm-backup/YYYY/MM/.
Right-click and drag-drop protection toggles in settings.

Initial Pro release.
Unlimited templates (removes free's one-template limit).
Dynamic placeholders — {{date}}, {{user}}, {{ip}}, {{copyright}}, {{post_title}}, {{site_name}}, {{site_url}}.
On-the-fly (OTF) display with disk cache at uploads/ultimate-watermark-frontend-cache/.
Display tab in the watermark builder for OTF settings (apply to content / thumbnails / WooCommerce, role bypass, cache toggle).
WooCommerce integration — product image and gallery handling, bulk batches, product_cat / product_tag rules.
Advanced conditional rules: file type, image dimensions, file size, orientation, aspect ratio, date range, post category.
Background batch processor (wp_schedule_single_event queue, 10-image chunks).
License manager + EDD-based auto-updates.
