Key enhancements

Platform modernization

The Vixen codebase now targets .NET 10 LTS, representing one of the most significant under-the-hood updates in recent releases. This work includes runtime modernization, updated libraries, installer and build workflow improvements, binary serialization corrections, and cleanup of deprecated platform-specific patterns.

VIX-3781 - Upgrade project to .NET 10 LTS
VIX-3832 - Configure the build workflow to utilize a specific .NET SDK
VIX-3869 - Correct binary serialization issues surfaced during the modernization effort
VIX-3966 - Update dependencies to current versions
VIX-3932 - Update libraries for security vulnerability

Universal Live Preview

Live preview capabilities were reworked to support a more universal architecture. The release introduces shared live preview infrastructure, project-wide messaging updates, and web server refactoring intended to simplify future preview integrations and improve maintainability.

VIX-3925 - Universal Live Preview: shared LivePreview module, Vixen.Messages broadcast project
VIX-3856 - Convert deprecated web host usage in the web server project
VIX-3928 - Add transparent background mode to Preview viewer
VIX-3768 - Hide locked preview elements

Falcon Player direct upload

Export workflows now support direct upload to Falcon Player (FPP), reducing manual steps after sequence export and enabling a smoother handoff from sequencing to playback infrastructure.

VIX-3922 - Add FPP Direct Upload capability to Export Wizard
VIX-3921 - Add FPP REST API client module

State property and State effect

Vixen 3.13 adds a new State effect and the supporting property model needed to build workflows around state-driven sequencing. This includes editor support, mapping helpers, and integration into the custom prop editor.

VIX-3924 - Create the State Effect
VIX-3591 - Create the State property and the mechanisms to apply it
VIX-3929 - Add and edit the State property in the Custom Prop Editor
VIX-3942 - Add element setup helper for the State property
VIX-3953 - Fix save behavior when adding a new State in the mapping helper

Element Tags foundation

This release introduces the foundational infrastructure for Element Tags, including core APIs, persistence, assignment services, and workflow-level integration. These changes establish a base for richer organization and targeting scenarios across display setup, preview setup, and sequencing.

VIX-3933 - Element Tags core API and persistence
VIX-2690 - Element Tags workflow across Display Setup, Preview Setup, and Sequencer
VIX-3931 - Widen public APIs from ElementNode to IElementNode

Notable user-facing improvements

New waveform height lock option and ruler height lock option for more consistent timeline layouts.
Improved mark handling, including scrolling while moving marks and better selection behavior.
Support for cloning effects with constrained vertical-only movement using Ctrl+Shift drag.
Move timeline cursor directly to the selected effect start.
Additional target node selection and depth support for the Wipe effect.
Transparent preview background mode and improved preview setup responsiveness.
Direct support improvements for custom props, fixture workflows, and xModel import scenarios.

Stability and bug fixes

This release contains broad reliability work across the application. Particularly notable fixes include:

VIX-3981 - Fixed a crash when a video effect is added without selecting a file and the sequencer is closed
VIX-3973 - Fixed a crash when editing a fixture property row from Display Setup
VIX-3972 - Corrected Fixture Wizard row selection issues
VIX-3910 - Fixed broken OpenGL Preview behavior introduced during cleanup work

Upgrade guidance

Review any environment or plugin dependencies that may be sensitive to the .NET 10 LTS runtime transition.
Test export workflows, especially if adopting new FPP direct upload capabilities for the first time.
For advanced display and prop setups, verify State property mappings and Element Tag workflows after upgrade.
