Versioning Policy
WEDA Core and WEDA Node are versioned separately. This page explains which version combinations are fully supported, and how WEDA Node keeps itself up to date.
Matching WEDA Core and WEDA Node versions
WEDA Core and WEDA Node are released on separate lines and carry their own version numbers, so the two numbers are not meant to look identical. Only the first two numbers decide compatibility.
| WEDA Core | WEDA Node | |
|---|---|---|
| Version format | v1.1.2-20260831.2 | v1.1.1_20260723.1 |
| Decides compatibility | 1.1 | 1.1 |
| No effect on compatibility | .2-20260831.2 | .1_20260723.1 |
In the example above both are 1.1, so WEDA Node v1.1.1_20260723.1 is fully
compatible with WEDA Core v1.1.2-20260831.2.
When the first two numbers do not match, the device keeps working but some features are unavailable.
| WEDA Core | WEDA Node | Result |
|---|---|---|
| v1.1.2-20260831.2 | v1.1.1_20260723.1 | Fully compatible |
| v1.1.2-20260831.2 | v1.0.0_20260415.1 | Device works, some features unavailable |
| v1.0.0-20260410.1 | v1.1.1_20260723.1 | Device works, some features unavailable |
WEDA Node automatic upgrades
WEDA Node keeps its own services up to date on the device. There is no manual upgrade step for you to run.
Automatic upgrades are always on and cannot be turned off in this release. Plan for the behavior below rather than around it.
When upgrades happen
WEDA Node checks for updates every 5 minutes. There is no maintenance window, so an upgrade can start at any time of day.
What happens on the device
An upgrade replaces the running services instead of swapping them in place, so the WEDA Node services stop and start again. Expect a service interruption of under 10 seconds.
Checking the installed version
Run this on the device:
/opt/Advantech/show-weda-versions.sh
Confirming an upgrade succeeded
Two ways to check:
- On the device,
docker psshows the state of the WEDA Node services. - From WEDA Core, the device's online state and version information are available through the API.
