The wrynose branch of meta-mender is now available!
Wrynose is the current long-term support (LTS) release of the Yocto Project (Yocto 6.0) and follows the scarthgap (Yocto 5.0) LTS. With the release of the meta-mender wrynose branch, the kirkstone branch of meta-mender also reaches the end of support and will no longer be maintained.
Default components: Major versions changed
meta-mender selects the default version of each Mender component automatically when one is not previously pinned. With the move to Wrynose, two components now default to a new major version:
|
Component
|
Previous default (scarthgap)
|
New default
(wrynose)
|
|
mender-connect
|
2.3.2
|
3.0.0
|
|
mender-gateway
|
1.2.1
|
2.0.0
|
When building images without pinning a previous version, Mender will automatically default to the new major versions.
To stay on the previous series, pin the version explicitly in the configuration, for example:
PREFERRED_VERSION_mender-connect = "2.3.2"
PREFERRED_VERSION_mender-gateway = "1.2.1"
All other Mender components keep the same default major versions as the scarthgap branch.

Updated bootloader and build integration
Adding Yocto 6.0 support to meta-mender required several compatibility updates.
If maintaining custom recipes or .bbappend files, please note:
- U-Boot: The U-Boot component is updated to 2026.01, including refreshed Mender integration patches and updated boot-environment handling.
- GRUB: The GRUB integration is consolidated on the 2.12 precompiled images; legacy precompiled builds have been removed.
- Poky: With the Wrynose Yocto release, Poky is now distributed as separate repositories — openembedded-core and bitbake — rather than a single combined repo. For self-maintained bblayers.conf, double-check the layer paths against the current Yocto setup and update accordingly; the meta-mender layer will update automatically.
- Recipes: All recipes have been migrated from WORKDIR to UNPACKDIR to follow the updated Yocto source-unpacking model. Custom .bbappend files that reference ${WORKDIR} for source or installed files will likely need to be updated to ${UNPACKDIR}.
