   - When multiple valid commits are published for the same epoch, clients converge on the same "winning" commit.
   - If a "better" commit (earlier timestamp) arrives after a "worse" commit has been applied, the client automatically rolls back to the previous epoch and applies the winning commit.
   - This ensures consistent group state across all clients even with out-of-order message delivery.
+- Upgraded `nostr` dependency from 0.43 to 0.44, replacing deprecated `Timestamp::as_u64()` calls with `Timestamp::as_secs()` ([#162](https://github.com/marmot-protocol/mdk/pull/162))

 ### Changed
 
+- Upgraded `nostr` dependency from 0.43 to 0.44, replacing deprecated `Timestamp::as_u64()` calls with `Timestamp::as_secs()` ([#162](https://github.com/marmot-protocol/mdk/pull/162))
 - **Persistent Snapshots**: Implemented snapshot support by copying group-specific rows to a dedicated snapshot table. `create_group_snapshot`, `rollback_group_to_snapshot`, and `release_group_snapshot` persist across app restarts. ([#152](https://github.com/marmot-protocol/mdk/pull/152))
 - **Unified Storage Architecture**: `MdkSqliteStorage` now directly implements OpenMLS's `StorageProvider<1>` trait instead of wrapping `openmls_sqlite_storage`. This enables atomic transactions across MLS and MDK state, which is required for proper commit race resolution per MIP-03. ([#148](https://github.com/marmot-protocol/mdk/pull/148))
   - Removed `openmls_sqlite_storage` dependency

 ### Breaking changes
 
 - **Security (Audit Issue M)**: Changed `get_message()` to require both `mls_group_id` and `event_id` parameters. This prevents messages from different groups from overwriting each other by scoping lookups to a specific group. ([#124](https://github.com/marmot-protocol/mdk/pull/124))

 - Changed `get_messages()` to accept optional `limit` and `offset` parameters for pagination control. Existing calls must be updated to pass `None, None` for default behavior (limit: 1000, offset: 0), or specify values for custom pagination. ([#111](https://github.com/marmot-protocol/mdk/pull/111))
