What is Scalar?

Scalar is testing demand for hosting from inside localhost

The October 1.76 run put a sticky developer toolbar above the API reference on localhost, with Configure, Share, Deploy and Generate SDK tools in a side panel. The Deploy tool now shows a waitlist for API hosting on Scalar, and 1.76.4 records the server framework with each sign-up. AsyncAPI rendering kept improving, with binding schemas shown as structured properties. In another package line, 0.20.0 moved to Undici 8 with HTTP/2 on by default and raised the minimum Node.js version to 22.19.0.

What is Talos Linux?

Talos 1.15's alpha keeps moving: a silent containerd config trap and declarative CPU control

Talos is on v1.15.0-alpha.2 while stable branches keep receiving maintenance releases such as v1.13.12. The alpha adds boot partition waiting for late-enumerated disks, container swap limits and a declarative CPUScalingConfig document. It also generates containerd configuration version 4, under which settings that moved between versions are silently ignored in custom CRI configs apart from a logged warning.

Scalar is testing demand for hosting from inside localhost

◆ Current state

The October 1.76 run put a sticky developer toolbar above the API reference on localhost, with Configure, Share, Deploy and Generate SDK tools in a side panel. The Deploy tool now shows a waitlist for API hosting on Scalar, and 1.76.4 records the server framework with each sign-up. AsyncAPI rendering kept improving, with binding schemas shown as structured properties. In another package line, 0.20.0 moved to Undici 8 with HTTP/2 on by default and raised the minimum Node.js version to 22.19.0.

◆ Where it's heading

The reference is becoming a dev-time workbench, not only a published page. Tools that sat in dropdowns moved to a persistent panel, and SDK generation was consolidated there. The hosting waitlist is the commercial signal: Scalar is collecting framework data from developers at the moment they run their API locally, which gives it a demand measure before committing to a deployment flow. AsyncAPI work remains the other steady investment.

◆ Prediction

Expect the waitlist to turn into a hosting beta, with the first supported frameworks chosen from the data 1.76.4 collects; FastAPI, Hono and Express are already named for detection. The monorepo's patch cadence should otherwise continue daily or near it.

Talos 1.15's alpha keeps moving: a silent containerd config trap and declarative CPU control

◆ Current state

Talos is on v1.15.0-alpha.2 while stable branches keep receiving maintenance releases such as v1.13.12. The alpha adds boot partition waiting for late-enumerated disks, container swap limits and a declarative CPUScalingConfig document. It also generates containerd configuration version 4, under which settings that moved between versions are silently ignored in custom CRI configs apart from a logged warning.

◆ Where it's heading

The 1.15 cycle extends Talos's habit of replacing kernel arguments and raw system settings with typed configuration documents. Networking dominated 1.14 and the first 1.15 alpha; alpha.2 widens that approach to hardware and resource control, and consolidates talosctl around a shared --namespace flag. The containerd change is the real operational cost of the cycle, because a customized metrics or gRPC section stops taking effect with only a logged warning.

◆ Prediction

Expect more typed documents for settings that still live in kernel arguments or SysfsConfig keys, and further alphas before a beta. Operators with CRICustomizationConfig patches should expect migration guidance to feature in the eventual 1.15 upgrade notes.
