OpenSlides 1.2.0

What's New

• This is the first major OpenSlides package built from the Svelte rewrite instead of the earlier React app.
• Preview, highlight, and code-transition rendering are much more stable, including fixes for random flickering or teleporting tokens during transitions.
• The editor, settings drawer, slide management flow, and dashboard stack interactions all received major usability and reliability improvements.
• Release packaging now covers macOS Apple Silicon, macOS Intel, macOS Universal, Windows x64, Windows ARM64, and Linux .deb / .rpm packages.

Major update: the Svelte desktop app

• OpenSlides now ships as the new Svelte-based desktop app, replacing the older React implementation for packaged releases.
• The presentation, editor, preview, and settings flows were refined across this rewrite so the app feels more consistent and native in daily use.
• Build and packaging settings were also tightened to produce leaner release binaries and cleaner production bundles.

Transition, preview, and highlight fixes

• Fixed random flickering, skipped morphs, and token teleporting during code transitions.
• Fixed line-number toggles causing Shiki Magic Move layout/schema glitches during live preview updates.
• Improved highlight measurement, underlay restoration, and theme-rekey stability so highlight overlays stay aligned more reliably.
• Reduced slide/preview desync cases during rapid editing, presenting, and theme changes.
• Preserved highlight behavior more safely during settings changes, overlay transitions, and preview re-renders.

Editor and workflow improvements

• Fixed the editor find/replace flow so the find bar opens reactively and keeps focus where expected.
• Improved match navigation so entering and stepping through search results behaves more predictably.
• Removed the no-longer-needed save-status badge from the editor toolbar.
• Fixed multi-select slide delete behavior so selected counts stay in sync after per-slide deletion.
• Added undo support for bulk slide deletion and made slide restore flow more dependable.

Settings and UX improvements

• Overhauled the presentation settings drawer with a more polished tabbed layout.
• Added global highlight controls for dim amount, pop size, and highlight dim color.
• Improved theme browsing, theme previews, layout controls, and drawer behavior.
• Centralized more defaults and runtime configuration so frontend/backend settings are less likely to drift apart.

Dashboard and stack spread improvements

• Reworked the stacked-project spread animation several times and migrated it to @humanspeak/svelte-motion.
• Smoothed card spread/pop timing and fixed close-state flashing artifacts.
• Improved fan/spread behavior for opening, closing, and dragging grouped project cards.

Packaging and platform coverage

• macOS builds now publish all three package variants:
  • Universal
• Windows builds now publish:
  • x64
  • ARM64
• Linux builds now publish:
  • .deb
  • .rpm
• Linux users should read the README download section for installation guidance before installing packages.
