 | Change | Description |
 | ------ | ----------- |
-| Support the new `tlx` SoC family ([#203](https://github.com/telink-semi/hal_telink/pull/203)) | Adapt the CMake build system for `CONFIG_SOC_FAMILY_TELINK_TLX`: `SOC_FAMILY` is set to `tlx` so the controller driver path resolves correctly; update the mbedtls ECP acceleration and IEEE802.15.4 include conditionals; keep the legacy TLX Kconfig symbols working for backward compatibility |
-| Role-based BLE controller library variants ([#205](https://github.com/telink-semi/hal_telink/pull/205)) | Replace the `COMPILE_TL_LIB_GENERAL` option with the `TL_BLE_CTRL_VARIANT` Kconfig choice (`TL_BLE_CTRL_PERIPHERAL` / `TL_BLE_CTRL_CENTRAL` / `TL_BLE_CTRL_MULTIROLE`), auto-selected from the BLE role configs; controller library names change from SoC-based (`_dual_core` / `_single_core` / `_general` / `_concurrent`) to role-based (`_peripheral` / `_central` / `_multirole`) |
-| Dynamic suspend-exit latency ([#205](https://github.com/telink-semi/hal_telink/pull/205)) | Remove the per-SoC hardcoded `SUSPEND_EXIT_LATENCY_US` macros from `tlx_bt_init.c`; the BLE library now records the suspend-exit start tick (`blc_ll_get_suspend_exit_start_tick`) for more accurate runtime latency handling |
-| Driver source sync ([#202](https://github.com/telink-semi/hal_telink/pull/202)) | Sync the hal_v2 wrapper with the latest Telink BLE SDK driver source changes (e.g. RF power control in `tl_rf_power.c`) |
+| HAL v2 rework cryptography unit | Synchronize cryptography with HAL v1: fix HW SHA in multi-thread environment, support all SHA types (not only SHA-256), add HW acceleration for tinycrypt, and clean up the SW structure |
+| Update signature verification ([#209](https://github.com/telink-semi/hal_telink/pull/209)) | Accelerate signature verification for ECDSA keys using the Telink HW PKE module |
+| Update tl5218x LPD level | Update the LPD (low power) level for `tl5218x` with driver confirmed |

 - Use `west update` to automatically pull `telink_ble_sdk` along with other modules.
-- Alternatively, manually fetch `telink_ble_sdk` by running `./hal_v2/fetch_sdk.sh {REPO_URL} {COMMIT_HASH}` inside `modules/hal/telink/` to pull or update the BLE stack to the version pinned by this release, where `{COMMIT_HASH}` is the `telink_ble_sdk` revision in `west.yml`.
