 ## [3.2.0] - 2026-05-02
 
+### Added
+- Generic CRUD UI for Item Tags (replaces NFC/QR scan flow)
+- Client-side length caps and truncation for Shop name and description
+- Date + time on `completedAt` timestamps via `cardDateTimeString`
+- Tests for Onboarding model, MainActivityViewModel, and AuthInterceptor
+- `canCreateItemTags` / `canDeleteItemTags` permission tests on `ItemTagListViewModel`
+- Configurable API endpoint via Gradle properties in Debug builds
+
 ### Changed
-- Normalized substrate naming to a single `NativeAppTemplate` stem: renamed all `Nat`-prefixed Kotlin symbols (and 8 source files), `Theme.Nat*` styles, `NATEMPLATE_API_*` Gradle properties, and the `NATA-XXXX` error-code prefix.
+- Renamed "Number Tag" to "Item Tag" throughout the app
+- Updated ItemTag schema to Rails API v2
+- Collapsed 7-tier role hierarchy to `admin` / `member`
+- Slimmed onboarding from 6 to 4 slides and replaced hero imagery
+- ItemTag list card now uses a two-column row layout with vertically centered content
+- Swipe actions reveal from the trailing (right) edge; renamed `reset` → `idle`
+- Card date format changed to `yyyy/MM/dd`
+- Renamed `validateEmail` → `isValidEmail`; converted `isNumeric` to a `String?` extension
+- Normalized substrate naming to a single `NativeAppTemplate` stem (Kotlin symbols, theme styles, Gradle properties, error-code prefix)
+
+### Removed
+- NFC, QR, and Scan features (background tag reading, scan view, camera permission)
+- "How To Use" entry from Settings
+- Server-driven `maximum_name_length` (moved to client-side `NativeAppTemplateConstants`)
+- Success toast for swipe complete/idle actions (reload is the success signal)
+- Unused Teal10/Teal30/Teal90 color tokens
+- Unused FileProvider declaration and `filepaths` resource
+- NATIVEAPPTEMPLATE-3xxx NFC/scan error code range
+- Dead code across `utils` and `designsystem`
+
+### Fixed
+- ItemTag whitespace-only name now fails validation
+- Long shop names no longer overflow the right column in `ShopDetailCardView`
+- Shop description field height regressed after switching to two-line `supportingText`
