Dear EtherLab users,
I am happy to announce the first release candidate of the data-logging
service (DLS) version 1.4.0-rc1 .
There has been appreciable progress on different topics:
- First of all there is the new Qt-based data viewer *dlsgui* ,
replacing the former (and still available) dls_view. The GUI uses a Qt
widget library *DlsWidgets*, which is also a Qt designer plug-in. Thus
the Graph widget can be easily included in Qt applications.
- A network protocol has been developed to access data from remote
hosts. The client implementation is part of the *libdls*, so both
*dlsgui* and the command-line tool *dls* transparently support
networking. In this way remote data access has been essentially
improved, because only the visible data are actually transferred.
- The daemon *dlsd* now uses the PdCom library  to connect to data
sources. This brought the advantage, that triggering on signals and
logging messages is now also possible.
- The *libdls*, *DlsWidgets* and *dlsgui* have been optimized for
platform independence and now can be built for Linux and Windows (for
example via MinGW). The *dlsgui* is available as Windows binary in the
download section on etherlab.org .
An overview of the most important changes can be seen in the NEWS file
on Sourceforge .
Sources are available on etherlab.org  and Sourceforge . Binary
packages for openSUSE are available on Open Build Service . Other
distributions could be added. If anyone is familiar with building .deb
package recipes and wants to help extending the supported distributions,
please contact me.
