@@ -19,6 +19,7 @@ Docs: https://docs.openclaw.ai
 - iOS/TestFlight: add a local beta release flow with Fastlane prepare/archive/upload support, canonical beta bundle IDs, and watch-app archive fixes. (#42991) Thanks @ngutman.
 - macOS/onboarding: detect when remote gateways need a shared auth token, explain where to find it on the gateway host, and clarify when a successful check used paired-device auth instead. (#43100) Thanks @ngutman.
 - Onboarding/Ollama: add first-class Ollama setup with Local or Cloud + Local modes, browser-based cloud sign-in, curated model suggestions, and cloud-model handling that skips unnecessary local pulls. (#41529) Thanks @BruceMacD.
+- Memory: add opt-in multimodal image and audio indexing for `memorySearch.extraPaths` with Gemini `gemini-embedding-2-preview`, strict fallback gating, and scope-based reindexing. (#43460) Thanks @gumadeiras.
