Canonical announces Zephyr 26.04 LTS

Read on canonical.comLobsters 12

Summary

Canonical announced Zephyr 26.04 LTS, an enterprise‑grade RTOS with up to 15 years of security updates and built‑in OTA support via Golioth. It’s delivered through Ubuntu Pro for Devices and includes a containerized development environment to simplify MCU firmware builds.

  • Zephyr 26.04 LTS offers up to 15 years of security maintenance, exceeding upstream's 5‑year support to satisfy EU CRA requirements.
  • Native integration with Golioth Cloud provides turnkey OTA updates and credential provisioning for microcontrollers.
  • Canonical Workshop supplies a containerized Zephyr environment, letting developers run west builds instantly without manual toolchain setup.
  • LTS release cadence mirrors Ubuntu: major LTS every two years, interim releases every six months, with support for tooling like West.

Device makers and OEMs building MCU‑based products should care because the LTS offering gives them extended security updates and integrated OTA tooling to meet regulatory compliance.

  5. OpenTelemetry everywhere: Migrating a metrics platform at scale

    Atlassian replaced its decade‑old gostatsd‑based metrics pipeline with a fully OpenTelemetry‑based stack by keeping the StatsD‑UDP contract on the client side and swapping in purpose‑built OTel Collector distributions for collection, ingest, aggregation, and forwarding. The migration was done incrementally, saved ~3.9% CPU per service, cut sidecar cost ~30% fleet‑wide, halved aggregation CPU, and…

  6. Article: Your Next DSL Author Is a Language Model

    Typed Domain Grounding (TDG) embeds a DSL inside a mainstream language the LLM already knows (e.g., Kotlin) and uses the host compiler as an oracle. The author describes five building blocks—embedding, choosing a host language with high training‑data frequency, compiler‑driven type safety, a generate‑compile‑repair loop, and an on‑demand teaching tool—and shows measured results from kUML, a Kotli…
