[ANNOUNCE] 412k

[Pyry Kovanen]

Urbit OS 412k is targeted for release on ~2023.9.25. This major kelvin release has the following highlights:

%lick, a vane for opening a IPC socket to Earth. In pre-release testing this vane has been used to control IOT devices and building a snake game.

The open %eyre. Every unauthenticated HTTP request to your urbit is now a comet, allowing them to poke and subscribe to Urbit applications without having to write annoying HTTP plumbing.

Eauth allows people to log in with their own identities on HTTP endpoints served by any ship. An example use case for this functionality would be a comments section on a blog served to the clearweb.

App developers should follow the migration instructions here: https://gist.github.com/pkova/6ddc65aa2ca192d0efa8667a36bac177. Note that any app developers involved in pre-release testing of 412k will not need to make any additional changes.

A release candidate (https://github.com/urbit/urbit/releases/tag/412k-rc2) is now live on ~marnec-dozzod-marzod.

A vere release that declares compatibility with 412k is imminent, all users should upgrade as soon as possible.

Full release notes will be coming later, interested parties can check out the 412k release candidate notes at https://github.com/urbit/urbit/releases.

Tlon's moons won't begin distributing the OTA until early next week. If you'd like to receive it before then you can run `|ota ~zod`.
