Version: 26.2 (stable)

Upgrade HELIO to 26.2.0

HELIO 26.2.0 does not introduce breaking changes. The notes below document a few behavioral changes that may be relevant while working with the IDE.

Before the Upgrade

Before beginning any version-specific upgrade steps, be sure to follow all the steps in the Before the Upgrade guide.

Upgrade Notes

"Main Action" Renamed and Integrated Into "Container" Settings

HELIO-6747 The Main Action property, previously found on individual elements, is now supported uniformly across all elements that have a Container and has been integrated into the Container settings. It is now simply called Action.

No Action Required

Existing projects are migrated automatically.


Renaming in the Content Tree Is Now More Predictable

HELIO-7368 HELIO used to synchronize an element's name in the HMI Content Tree with its Title/Label property in both directions — a logic that could lead to unintended data loss, for example silently overwriting a Title connected to a Data Variable when the tree name was changed.

With HELIO 26.2, this is replaced by a simpler heuristic: by default, an element's tree name is still derived from its Title/Label property. It will still be translated automatically if that property is connected to a Localizable Text. As soon as you manually rename the element in the tree, that name takes over — HELIO no longer syncs it back into the properties.

Clear the Name to Resume Syncing

To go back to the automatic behavior, simply rename the element in the tree and clear the name field. HELIO will then resume deriving the tree name from the element's Title/Label property.


Mission accomplished!

You've successfully upgraded to HELIO 26.2.0.
Happy HMI Engineering!
