# Change Log
## [v4.1.1](https://github.com/ARMmbed/mbed-coap/releases/tag/v4.1.1)
**Closed issues:**
- IOTCLT-2203 mbed-coap does not handle PUT or POST if they indicate a smaller block size preference (fixed regression)
-[Full Changelog](https://github.com/ARMmbed/mbed-coap/compare/v4.1.0...v4.1.1)
