Draft text (thx Arne!) for release message:
<pre>
We are happy to announce the release of version 0.7 of RSB. The development
activities in this cycle focused on
* TCP socket transport introduced and default
* Error recovery, robustness and featrues of RSB and RSBag tools
* End-user documentation
* Packaging and deployment

In the process, about 70 issues have been created and subsequently resolved.

This RSB release is available in the following forms:
* Source archives
* Pre-compiled self-installing archives or executable binaries
* Debian packages for different Ubuntu Linux versions
* Prototypical homebrew recipes and pypi packages

Installation instructions and links for downloading can be found on the
preparation page of the RSB end-user documentation:
http://docs.cor-lab.de/rsb-manual/0.7/html/

As always, bugs, feature requests and enhancement proposals can be reported in
the respective issue trackers:
"RSB":https://code.cor-lab.org/projects/rsb/issues,
"RSBag":https://code.cor-lab.org/projects/rsbag/issues.

*Please note that:*
# *Only TCP socket transport is now enabled by default.*
# *Log files recorded with the 0.7 version of RSBag cannot be processed with
older RSBag versions.* The opposite direction works, though.

For transport configuration issues see
"troubleshooting":http://docs.cor-lab.de/rsb-manual/0.7/html/preparation.html#troubleshooting
