Breaking Changes

●Issue #1

If you are on v5.9.1 or older, you must update to the latest installer/launcher (v1.5.0) or the update may fail.

●Issue #2

When starting Invoke for the first time after updating to v5.10.0, your Form Builder state will be reset, causing loss of unsaved changes. Users must save their current workflow before updating and manually reload it afterward.

Migration Steps

  1. 1
    If using v5.9.1 or older, download and use the latest installer/launcher (v1.5.0) to ensure a successful update.
  2. 2
    If the installation fails, retry the installation with **repair mode** enabled (tick the checkbox on the **Review** step of the install) to resolve Python environment conflicts.
  3. 3
    Before updating, save any unsaved workflow changes, as the Form Builder will reset upon first launch after updating.

Release Summary

This release introduces a major new model drop-down component and critical installation updates requiring the latest launcher (v1.5.0). Users must take specific steps to ensure a smooth upgrade, including backing up Form Builder state.
