  - Added `factory.destroy()` method, which invokes the `destroy` method on all SDK clients created by the factory.
  - Bugfixing - Fixed an issue with the server-side polling manager that caused dangling timers when the SDK was destroyed before it was ready.
  - BREAKING CHANGES:
-   - Removed the deprecated `GOOGLE_ANALYTICS_TO_SPLIT` and `SPLIT_TO_GOOGLE_ANALYTICS` integrations.
    - Updated default flag spec version to 1.2.
    - Removed `/mySegments` endpoint from SplitAPI module, as it is replaced by `/memberships` endpoint.
    - Removed support for MY_SEGMENTS_UPDATE and MY_SEGMENTS_UPDATE_V2 notification types, as they are replaced by MEMBERSHIPS_MS_UPDATE and MEMBERSHIPS_LS_UPDATE notification types.
+   - Removed the deprecated `GOOGLE_ANALYTICS_TO_SPLIT` and `SPLIT_TO_GOOGLE_ANALYTICS` integrations.
+   - Removed the migration logic for the old format of MySegments keys in LocalStorage introduced in JavaScript SDK v10.17.3.
+   - Removed the `sdkClientMethodCSWithTT` function, which handled the logic to bound an optional traffic type to SDK clients. Client-side SDK implementations must use `sdkClientMethodCS` module, which, unlike the previous function, does not allow passing a traffic type but simplifies the SDK API.
+   - Removed internal ponyfills for `Map` and `Set` global objects, dropping support for IE and other outdated browsers. The SDK now requires the runtime environment to support these features natively or to provide a polyfill.
 
 1.17.0 (September 6, 2024)
  - Added `sync.requestOptions.getHeaderOverrides` configuration option to enhance SDK HTTP request Headers for Authorization Frameworks.
