History of LASE versions
This page describes briefly the changes, improvements and
corrections of each new version (often, there is more than is just
presented here, especially when a long time separates two
versions). They are sorted by invert chronological order.
2016, december the 29th
A very long time since the last update of the web site, but not of
LASE itself. Briefly, main changes concern the internal structure of
the source code, with a more clear separation between the graphical
interface part and the core. This should allow an easier adaptation
to other kind of graphical interface (native Mac OS X support or
more functionnal Windows support, for instance). This should also
help the translation process. Last, it allows the use of UTF-8 as
the native format for strings and graphical interface (which may not
be so much a concern for English users…).
Other changes concern the "decomposition" part (try to express a
graph as a linear combination of other graphs), which is now handled
through the generic model interface and allows an arbitrary number
of graphs to be used to construct the linear combination.
Please signal me any dysfunction introduced by this new
structuration.
2003, october the 9th
Only X-window version is concerned, because of a lot of changes in
the GUI library to allow quickest addition of new options.
Beside of bug correction, some big news in that version:
- images are now handled like graphes (use of séries, more
various nature of data at each point). Also, the images main
window was updated and now presents the color scale.
- ASCII import was rewrote and is more flexible now. Please read
documentation for more details.
- experimental (or semi-empirical) data used by LASE are now,
for most of them, isolated from the code source and placed in separate
files read "on the fly". Hence, user can update or adapt these files
without going into the detail of the LASE code source. And, if not
used, they do not waste memory. These data are grouped in the
directory share/Lase, and are for the moment:
- edge energies,
- fluorescence line energies,
- fluorescence line yields,
- fluorescence line natural width,
- space-group symmetry operations.
- LASE now includes a model for simulating an experiment,
including various systematical effects. This model is
still experimental. To try it, use Ctrl-X in
theoretical mode. If you are interested, please send me an
e-mail to get a copy of the corresponding documentation (in
English).
2003, july the 4th
Major evolution of LASE (now version 3.1). It is hard to abstract
all changes from more than on year, here come the most importants (but
many other improvements are present):
