 # Release Notes
 - v4.2.0(TBD)
-  - Added support for async I/O. Asynchronous version of connector is available via `snowflake.connector.aio` module.
   - Added `SnowflakeCursor.stats` property to expose granular DML statistics (rows inserted, deleted, updated, and duplicates) for operations like CTAS where `rowcount` is insufficient.
   - Added support for injecting SPCS service identifier token (`SPCS_TOKEN`) into login requests when present in SPCS containers.
   - Introduced shared library for extended telemetry to identify and prepare testing platform for native rust extensions.
-- v4.1.1(TBD)
+
+- v4.1.1(December 12,2025)
   - Relaxed pandas dependency requirements for Python below 3.12.
   - Changed CRL cache cleanup background task to daemon to avoid blocking main thread.
   - Fixed NO_PROXY issues with PUT operations
