 - **Metadata**: Optional filters (e.g., `{"category": "movie_recommendations"}`) that improve retrieval later.

+- **expiration_date**: Optional `YYYY-MM-DD` date after which the memory is treated as expired. Use `expirationDate` in the JavaScript SDKs. Expired memories are hidden from `search` and `get_all` unless you pass `show_expired` (`showExpired` in JavaScript); fetching by ID still returns them.

 <Note>
-  OSS JavaScript SDK does not expose `update` yet: use the REST API or Python SDK when self-hosting.
+  In both OSS SDKs the content is optional — pass only `metadata` and/or an expiration date to update those while keeping the existing content. At least one of the three must be provided, otherwise the call raises.
+</Note>
+
+<Note>
+  `data` is a deprecated alias for `text` in both OSS SDKs (`data=` in Python, `{ data: ... }` in JavaScript). It still works but logs a warning; prefer `text`. In JavaScript, passing a bare string is shorthand for `{ text }`, so `update(memoryId, "new text")` also still works.

 ### Methods
 
 - `add(messages: string | Message[], userId?: string, ...): Promise<SearchResult>`
+  - Options include `metadata`, `infer`, and `expirationDate` (a `YYYY-MM-DD` date after which the memory is treated as expired).
 - `search(query: string, userId?: string, ...): Promise<SearchResult>`
+  - Expired memories are omitted unless you pass `showExpired: true`.
 - `get(memoryId: string): Promise<MemoryItem | null>`
-- `update(memoryId: string, data: string): Promise<{ message: string }>`
+  - Fetching by ID returns the memory even if it has expired.
+- `getAll(options): Promise<SearchResult>`
+  - Expired memories are omitted unless you pass `showExpired: true`.
+- `update(memoryId: string, config: string | UpdateMemoryOptions): Promise<{ message: string }>`
+  - `UpdateMemoryOptions` is `{ text?, data?, metadata?, expirationDate? }`. At least one must be
+    provided; omitted fields are left untouched, and `expirationDate: null` clears an existing
+    expiry. `data` is a deprecated alias for `text`.
+  - Passing a bare string is shorthand for `{ text }`, so `update(memoryId, "new text")` still works.
 - `delete(memoryId: string): Promise<{ message: string }>`
 - `deleteAll(userId?: string, ...): Promise<{ message: string }>`
 - `history(memoryId: string): Promise<any[]>`
 - `reset(): Promise<void>`
