Hereby I introduce a ''Development Status'' page, where the current phase of the release cycle can be marked and similar status information is published. This page also includes the Changelog (from the file NEWS). Since updates must be checked into Git and then pushed to our website, such status marks are documented in the history. Some notes regarding the phases of the Release cycle were also added to the Release checklist. + some additional links resources and documentation tweaks

Lumiera -- Significant Changes
|
|
==============================
|
|
Version: 0.pre.05~dev
|
|
:Date: 11/2025
|
|
|
|
*************************************************************
|
|
Lumiera is a non-linear video editing and compositing tool.
|
|
|
|
NOTE: as of 11/2025, Lumiera is in early development stage;
|
|
it is not usable yet. This is a preview Release of a
|
|
current development snapshot in pre-alpha stage.
|
|
|
|
Source code and a list of all contributors can be retrieved
|
|
from `git://git.lumiera.org/LUMIERA`
|
|
*************************************************************
|
|
|
|
|
|
|
|
At the current stage of development, the focus is primarily on the
|
|
overall integration of fundamental functionality at all levels of
|
|
the code base.

Lumiera pre-Alpha Versions
|
|
--------------------------
|
|
|
|
As of _11/2025_ (0.pre.04)::
|
|
This version is 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.
|
|
|
|
As of _11/2015_ (0.pre.03)::
|
|
A lot of long standing maintenance work has been done.
|
|
The codebase has been upgraded to C++14 and Debian/Jessie as reference platform,
|
|
followed by clean-up of several workarounds now obsoleted. On the GUI side,
|
|
the transition to GTK-3 was accomplished, which however necessitates a rework
|
|
of our timeline widget, which is in progress but not finished yet. This work
|
|
also spurred an effort to reorder the connection and communication between
|
|
the core and the UI, which is expected to be asynchronous. Due to the limited
|
|
developer resources, work on the Engine and Player part is stalled.
|
|
|
|
As of _10/2013_ (0.pre.02)::
|
|
The data models have been elaborated and some significant parts of the session
|
|
are finished. Work has continued with time handling, a draft of the output
|
|
connection framework, a draft of the player subsystem and interfaces to the
|
|
engine and processing network. Unfortunately there was a considerable slowdown
|
|
and decrease in team size, yet still the code base is growing towards 90k LOC.
|
|
No tangible progress regarding the GUI and the backend.
|
|
|
|
As of _1/2011_ (0.pre.01)::
|
|
The project has created and documented a fairly consistent design,
|
|
and some parts implemented -- progressing from the technical foundations.
|
|
The code base is approaching 65k LOC. Roughly half of this is test code.
|
|
The Application can be installed and started to bring up a GTK GUI framework,
|
|
but the GUI is rather preliminary and not connected to core functionality.
|
|
The video processing pipeline exists only in the blueprints.
|
|
|
|
As of _2/2008_::
|
|
The project has been separated completely from Cinelerra, the parent project.
|
|
The Community, which at that time was largely identical to the Cinelerra-CV community,
|
|
choose the new project name **Lumiera** through a collaborative selection and vote.
|
|
The basic project infrastructure was established, and work on the new codebase
|
|
was underway. It is clear that no results other than a test suite can be shown
|
|
in the foreseeable future.
|
|
|
|
As of _7/2007_::
|
|
A group of volunteers has formed to address some longstanding issues and limitations
|
|
of **Cinelerra**, which we all used for video editing tasks requiring professional quality.
|
|
The plan was to restructure some central parts of the render engine: introduce a Builder
|
|
for render pipelines and use Placements to control arrangement of clips and a unified
|
|
Data-Backend to coordinate usage of system resources. These innovations would serve
|
|
as anchor, with the intention to propose the reworked codebase as a new version
|
|
of Cinelerra, in the hope of turning Cinelerra development into a more
|
|
participatory process going forward.
