Yoe v2021.12 - "masai" is released. This released includes ready to boot images for Raspberry PI4, and BeagleBone Black platforms. This is also the first release that is completely automated -- we push a tag, and then Github actions kicks off a build on our CI server, builds, tests, and uploads images.

Reading through this patchset -- seems to be a header cleanup which results in whopping 88% compile time improvement for linux kernel. Its not mentioned but I am sure Ingo might have used clang-include-fixer tool to support the cleanup effort.


Simple IoT v0.0.41 is out with support for NATs over websockets for upstream support. This is very useful when using SIOT on networks where all outgoing connections are blocked except for HTTP(S). This also makes handling TLS certs easier on servers as this can all be relegated to a webserver like Caddy.


We published two new episodes:
