v145.0 (2025-10-13)

✨ What's New ✨

Swift

• Added @unchecked Sendable to classes that conform to FeatureManifestInterface. (#6963)

Ads Client

• Added the Ads Client component to the Megazord.
• Updated the ApiError enum to AdsClientApiError to avoid naming collision.
• The context_id is now generated and rotated via the existing eponym component crate.

Relay

• ⚠️ Breaking Change: The error handling for the Relay component has been refactored for stronger forward compatibility and more transparent error reporting in Swift and Kotlin via UniFFI.
  • API and network errors from the Relay server are now converted to a single RelayApiError::Api { status, code, detail } variant, exposing the HTTP status code, a machine-readable error code (if present), and a human-readable detail message.
  • Downstream client apps can now handle server errors based on both the status and error_code fields directly, without additional changes to the Rust component - even as server-side error codes evolve.
  • Consumers must update their error handling code to match the new Api { status, code, detail } shape.

Places

• places::storage::history_metadata::get_most_recent(limit: i32) was added to get most recent history metadata limited to a number. (#7002)

FxA Client

• Expose getAttachedClients from the uniffi layer in the Android wrapper.

Docs

• Updated the components strategy doc to better reflect the current state of application services. (#6991)
