 ### Added
 
-* **Cache Naming:** Added `WithName` for assigning an optional cache name used by observability integrations.
 * **Cleanup Lifecycle:** Added `StartCleanup` and `StopCleanup` for explicitly controlling periodic expiration cleanup.
-* **Metrics Sources:** Added `MetricsSource` for exposing cache statistics to metrics integrations.
+* **Metrics Sources:** Added `MetricsSource` for exposing cache identity and statistics to metrics integrations.
 
 ### Changed
 
-* **Constructors:** `New` no longer accepts a cache name. `NewWithDefaultLoader` now accepts the loader directly,
-  followed by options.
-* **Metrics API:** Replaced `StatsProvider` and `MetricsRegistration` with `Metrics.Register(MetricsSource) error`.
+* **Constructors:** `New` no longer requires a cache name. Cache names are now optional through `WithName`.
+  `NewWithDefaultLoader` now accepts the loader directly, followed by options.
+* **Metrics API:** Replaced `StatsProvider`, `MetricsRegistration`, and `RegisterCache` with
+  `Metrics.Register(MetricsSource) error`. Metrics implementations now own the lifecycle of their registrations.
 * **Background Cleanup:** Cleanup is no longer started automatically during cache construction. `WithCleanupInterval`
   configures the cleanup interval, while `StartCleanup` runs the blocking cleanup loop explicitly.
-* **Cleanup Defaults:** Background cleanup uses a one-minute interval by default.
-* **Benchmarks:** Updated benchmark suites and comparisons for the current cache API.
 
 ### Removed
 
+* **Cache Name Accessor:** Removed `Cache.Name`; cache names are now optional and used by observability integrations
+  through `WithName`.
 * **Cache Close:** Removed `Cache.Close`; background cleanup is stopped explicitly with `StopCleanup`.
 
 ## extra/paceotel/v1.3.0
 
-This release aligns `paceotel` with the updated `pacecache` metrics API and simplifies metrics registration across
-multiple caches.
+This release aligns `paceotel` with the updated `pacecache` metrics API and moves metrics registration lifecycle
+management to the integration itself.
 
 ### Added
 
-* **Reusable Metrics:** A single `Metrics` instance can be shared across multiple caches.
 * **Source Validation:** Duplicate cache names are rejected within a `Metrics` instance, while a single unnamed cache is
   supported.
+* **Metrics Lifecycle:** Added `Metrics.Unregister` for removing registered OpenTelemetry callbacks and releasing
+  references to registered caches.
+* **Instrumentation Scope:** Added `ScopeName` and `Version` for exposing the OpenTelemetry instrumentation scope and
+  module version.
 
 ### Changed
 
-* **Metrics Registration:** Each cache now uses its own OpenTelemetry callback registration.
-* **Unregister Lifecycle:** `Metrics.Unregister` removes all registered callbacks, releases references to registered
-  caches, and prevents further registrations.
+* **Registration Ownership:** `Metrics` now owns the registrations for its cache sources instead of returning
+  per-cache registrations managed by `Cache`.
 * **Core Dependency:** Updated `github.com/mkbeh/pacecache` to v1.3.0.
