 ## [Unreleased]
 
+## [0.11.75] - 2026-05-31
+
+### Changed
+
+- **Server compatibility**: tracks Dakera server v0.11.75 (TieredEngine registered in
+  AppState, binary HNSW dispatch wired in search paths, ReembedJob spawned at startup).
+  No client API surface changes required — all existing calls work unchanged. Binary HNSW
+  is opt-in server-side via `DAKERA_SEARCH_MODE=hybrid`; the SDK sends requests identically
+  regardless of server search mode.
+
+## [0.11.57] - 2026-05-22
+
+### Added
+
+- **`storeMemoriesBatch()`** — new `DakeraClient` method for `POST /v1/memories/store/batch`,
+  enabling high-throughput batch memory ingestion (DAK-5508)
+  - `BatchStoreMemoryItem` — per-item fields matching the server batch schema
+  - `BatchStoreMemoryRequest` — `agentId` + `BatchStoreMemoryItem[]`
+  - `BatchStoredMemory` / `BatchStoreMemoryResponse` — response types
+
 ## [0.11.56] - 2026-05-17
