We just released Tracealyzer version 4.5.2. Users with a current support contract can upgrade from within the application, or by going to the update page and download the right binary for their platform.
With version 4.5.2, we continue to add stability and rendering improvements for Tracealyzer running on Linux hosts. In particular, we have restructured the layout engine that is responsible for placing windows on the screen. In addition, the new version provides improved memory estimation for some trace formats, including LTTng.
