v4.2.1

Changed

• Added --build-windows and --build-check flags to build scripts to allow optional skipping of Windows build and unit tests/mypy checks. One example scenario where this would be useful would be building an official version that has already been validated and unit tests already run, to reduce build time. Another scenario would be to skip the Windows build if the user only needs a Linux build.

Fixed

• RTC 538468 - paho-mqtt upgrade broke cloudadapter's mqtt connections. Fixed proxy setting code to not override all sockets with proxy as paho-mqtt 1.6.0 relies on listening/connecting to localhost to set up sockets, and this doesn't work with a global proxy on all sockets.
• RTC 538549 - improved errors when unable to fetch from URLs. For example, if INBM receives a "404 Not Found" it will return this as part of its error instead of simply returning a generic error message about being unable to fetch the URL.
• RTC 538524 - GUID missing when not provided by manifest when running fwupdate tool
• RTC 530960 - Fix SOTA snapshot conditions to not reboot twice on EXT4 system

Security

• RTC 537811 - Bump cryptography from 41.0.6 to 42.0.2 in /inbm/dispatcher-agent (addresses CVE-2023-5678, CVE-2023-6129)
