This is a **preview release** — Lumiera is not usable yet. Publication was again motivated by a series of major upgrades and clean-up. Compilation now requires C++23 and Debian/Trixie is considered the reference platform. The GUI is connected to the core over an asynchronous messaging bus and the timeline display has been reshaped to accommodate flexibly nested structures of media content, instructed by the session through a series of _diff messages_. A scheduler has been implemented to drive the Render Engine, but the connection to the player and UI for output is yet unfinished.
