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.
Some recherche regarding the requirements and conditions of the GPL
made it clear that we are obliged to have at least an summary statement
of all authors and the years of their contributions embedded somewhere
in the source itself. The Git history alone is not sufficient to fulfil
this requirement, since a code base could be packaged as Tarball
and passed-on outside of any Git repository.
Thus I propose the following policy
- add yourself to the copyright header whenever you made
some ''significant'' contribution to a code file
- maintain a list of relevant authors at top-level,
indicating a time range of their contribution
- use the same information also in the debian/copyright (DEB package)
- clarify in the LICENSE that authorship can be extracted from Git
__Remark__: Anton Yakovlev made a single code contribution in 2009 (87e528bd),
which was never used anywhere and removed as part of a general clean-up in 2023.
Thus I do not list him as a code author, but he is mentioned in credits.txt
- use a current copy of the GPL2 text, downloaded from fsf.org
- reformat the AUTHORS and get rid of the table formatting
- Stackoverflow has upgraded its Subscriber Content license to CC-By-SA 4.0
A handwritten changelog is considered important and
helps to single out the overall relevant achievements.
Following a proposal from the Debian policy, this summary
of development steps will now be maintained in the NEWS file.
It will be marked with the version number of Lumiera.
...and split-out the description of preview-releases,
since that rather belongs into some kind of changelog (NEWS).
