We are pleased to announce the Mbed OS 5.5.7 release is now available.

This release includes an update for mbed-coap to version 4.0.10, bootloader support for DISCO_L476VG and a critical workaround for 'STM32F439xI-family AES hardware acceleration occasionally produces incorrect output (#4928)' (achieved by disabling AES acceleration by default). There are also numerous bug fixes and code enhancements.
