 - Hello, World!
 - Initial PCD 2.0 schema definition
-  - Core entity tables: quality_profiles, custom_formats, regular_expressions,
-    languages, tags, qualities, quality_groups
-  - Custom format conditions system with 11 condition types (patterns, language,
-    indexer_flag, source, resolution, quality_modifier, size, release_type,
-    year)
-  - Quality profile system supporting individual qualities and quality groups
-  - Junction tables for tags, quality groups, profile qualities, and profile
-    custom formats
-  - Unique index ensuring single upgrade_until per profile

+- Unique index ensuring single upgrade_until per profile
+- Add arr_type support for Radarr/Sonarr differentiation
+  - custom_format_conditions.arr_type: conditions can be arr-specific or
+    universal
+  - quality_profile_custom_formats.arr_type: scores can differ between Radarr
