Version 1.8.0

KAsset Manager 1.8.0 Release Notes

Release Date: 2026-01-13

Overview

Version 1.8.0 transitions KAsset Manager's playback pipeline to tlRender (mrv2's engine),
bringing OCIO-aware video and image-sequence playback while retiring the legacy GStreamer
preview path. The release also aligns build, portable, and installer metadata with the
1.8.0 version.

Highlights

• tlRender (mrv2) playback engine now powers video and image-sequence previews
• OCIO color management available throughout the playback pipeline
• Legacy GStreamer preview runtime removed from packaging
• Build and installer metadata updated to version 1.8.0

User-Facing Changes

• Video and image-sequence playback now uses tlRender for consistent results across formats.
• GStreamer is no longer bundled or required for preview playback.
• Application versioning in build outputs and installers reflects 1.8.0.

Developer/Technical Notes

• CMake project version is set to 1.8.0 and Windows resources/installer metadata match.
• tlRender is consumed via its CMake package and provides bundled OpenColorIO/OpenImageIO.
• The build expects a tlRender install at third_party/tlRender-build/install-Release
  (see native/qt6/CMakeLists.txt for the candidate search paths).

Upgrade & Build

1. Reconfigure CMake (recommended):

cd native/qt6
cmake -S . -B build\ninja -G Ninja
cmake --build build\ninja --target kassetmanagerqt

Notes & Known Issues

• If you have a custom tlRender build location, ensure TLRENDER_ROOT or the expected
  install path is available before configuring.
