Turbine **26.1.3** includes a fix that restores reliable behavior for applet field keys on applications and playbooks that reference those fields.

# Addressed Issues

## Applications and Applets

- **Applet Field Keys Reverted to Dotted Notation:** In **26.1.2**, field keys for fields added to an application from an applet changed from dotted notation (for example, `abc.sla_status`) to underscore notation (for example, `abc_sla_status`). **26.1.3** restores the original dotted format for newly added applet fields. Field keys created on **26.1.2** are not changed automatically. If a playbook or **widget** was created or updated using those underscore keys and it worked before the hotfix, it should continue to work after the hotfix.
  If a Record Action maps the target application instead of selecting it from the dropdown, and that application still has underscore applet keys from **26.1.2**, the action may fail after the hotfix. To resolve this, remove the applet from the application and add it again so the fields regenerate with dotted keys. Then update any playbook, component, or widget mappings that still reference the old underscore keys.
