v0.66.1 hotfix

Release v0.66.1

May 20, 2026

Hotfix: desktop viewer and helper apps open again on the React 19 build that v0.66.0 introduced.

Fixed

  • Desktop viewer and helper apps failed to launch after upgrading to v0.66.0 because of a React 19 type-checking change in how component refs are initialized. Both apps now open normally again.

A one-line hotfix for a regression introduced in v0.66.0. The desktop viewer and helper apps shipped with v0.66.0 wouldn’t open on some systems after the React 19 upgrade. v0.66.1 corrects the initialization pattern so both apps launch as expected. No other changes. Anyone on v0.66.0 should upgrade if they use the desktop viewer or helper.
