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.
