v147.0

v147.0 (2025-12-07)

Relay

• Added fetch_profile() method to check premium subscription status via has_premium field (#7113)

Nimbus

⚠️ Breaking Changes ⚠️

• Removed unused home_directory field from AppContext. Both Kotlin and Swift sides were passing null values and it wasn't used anywhere. (#7085) (#30782)

rc_crypto

• Thread-safety improvements for PKCS-token-dependent methods by introducing a
  global mutex. Refactored key unpacking logic and removed redundant code;
  includes some breaking API changes, but since the keydb feature is not yet in
  use, these do not affect existing consumers.
  • get_aes256_key now returns a Result<Option<Key>> to distinguish missing
    keys from errors
  • get_or_create_aes256_key only creates a key when none exists.
  • When the keydb feature is enabled, ensure_nss_initialized is disabled in
    favor of ensure_nss_initialized_with_profile_dir.

Logins

• create_login_store_with_nss_keymanager returns an ApiResult now, instead
  of just panicking.
• fix count_by_origin and count_by_form_action_origin with punicode origins

Places

• places::storage::history_metadata::get_most_recent_search_entries() was added to fetch the most recent search entries in history metadata. (#7104)
• places::storage::history_metadata::delete_all_metadata_for_search() was added to delete the search terms in history metadata. (#7101)

✨ What's New ✨

Autofill

• Adds a migration to migrate users to use subregion codes over fully qualified strings. (bug 1993388)

Relay

✨ 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.
