Summary
Zephyr microPlatform changes for 0.7
The most significant change in this update follows the Linux microPlatform switch to a Linux v4.14-based tree. This impacts compatibility with any gateways relying on the old Bluetooth behavior, and also will cause changes to the MAC addresses reported by the Zephyr microPlatform sample applications. Users of the bt-joiner container whitelist feature in the Linux microPlatform will need to update their whitelists. Specifically, the leading D6:E7 in the MAC addresses must be changed to D4:E7.
Linux microPlatform changes for 0.7
This kernel update includes x86 support for kernel page-table isolation (KPTI), which mitigates the recent meltdown security vulnerability.

Bugs
LWM2M packet fix:
- The LWM2M stack includes a fix which prevents a packet which may need to be retransmitted from being freed until after this retransmission has completed, if necessary.
Zephyr FOTA Samples for Hawkbit
Features
CONFIG_NET_L2_BT_ZEP1656 disabled:
- This obscure option was used to preserve compatibility contrary to the Bluetooth specification with implementation characteristics in the Linux kernel. Now that the upstream Linux microPlatform was updated to v4.14, which has fixes for these characteristics, the option can be disabled.
dm-hawkbit-mqtt cleanups and optimizations:
- Various confusing implementation details in this application have been fixed and otherwise cleaned up. The resulting application now requires less memory.
Bugs
Packet pool workaround for MQTT:
- The dm-hawkbit-mqttt sample now uses an extra packet pool when the underlying link layer is Bluetooth. This keeps the network stack working in the face of IPv6 packet header compression.
