What happened

The Yocto Project announced its 6.0 “Wrynose” long-term support (LTS) release on 13 May 2026. The series is supported until April 2030 and includes Linux 6.18 LTS, toolchain updates, and improvements to software bill of materials (SBOM) generation and CVE tracking. [1]

According to the announcement, sbom-cve-check replaces the workflow based on the cve-check class, and SPDX 3 output has been improved. The migration notes for version 6.0 also confirm that support for generating SPDX 2.2 documents has been removed in favor of SPDX 3. [1] [2]

Why it matters for manufacturers

A migration affects the software running on the device as well as the build and reporting systems around it. A firmware image may build successfully even when downstream scripts still expect an older report format, class, filename, or configuration setting.

Review distribution-specific defaults carefully. For example, the default “nodistro” configuration moves to systemd, while Poky continues to use SysVinit by default. The impact of a release change therefore depends on the product’s actual configuration. [2]

Support until April 2030 helps with planning, but manufacturers still need to evaluate their BSP, layers, applications, hardware, and test coverage. Products remaining on an existing supported branch need continued maintenance while a larger migration is considered.

What to include in your migration plan

  • Pin the current and proposed configurations, including the BSP, layers, local patches, and relevant defaults.
  • Update tools that process SBOM and CVE reports, then confirm that each report still identifies the correct firmware artifacts.
  • Compare build, boot, connectivity, and application behavior against the existing product baseline.

The engineering takeaway

Treat an LTS migration as an update to the firmware and its build, test, and reporting processes. Reviewers should still be able to trace each change to the resulting artifacts and validation results.
