On Slack today :
We’re all really looking forward to the entire v3 stack. It will make so many things easier and better.
It’s indeed completely written in Go (including the Gateway Agent), so it can be cross-compiled for many CPU architectures (including several arm versions).
It’s still too early for nightly builds, I can imagine it will still take several weeks, maybe months before everything is working properly.
We want to open up the source code around this time (Q2), but the actual launch is planned for Q4 this year, so we still have enough time to actually make it work on all gateways.
