Hi all,

We are announcing the release of LTTng Scope 0.4.0.

This release has a few improvements over LTTng Scope 0.3:

* Open more than one trace thanks to the new "Trace Project Setup"
window. (e.g. Kernel + UST traces)

You can always reopen this window to add traces to or remove traces
from the current trace project by clicking
"File" -> "Project Setup..." or by right-clicking the project item in
the left pane and clicking "Project Setup".

* Event count chart: use vertical bars instead of an area chart. A given
bar indicates the number of event records of which the timestamps are
between the beginning and the end of the bar.

* Event count chart: use natural ticks, depending on the current zoom
level, on the horizontal (time) axis. For example, the difference
between individual ticks can be 100 ms, 500 ms, 1 s, 2 s, 15 s, 30
minutes, 1 day, etc.

* Event count chart: add axis units ("Count / Time") below the view's
title on the left.

* Add the version to the main window's title bar.

* Bug fix: refresh the views when you move vertical dividers or when you
resize the main window.

* Bug fix: event count chart: round tick labels correctly to avoid
noticing floating point number errors.

Of course, because LTTng Scope's development is still in the beta phase,
you could discover bugs when trying the tool. Feel free to report them
