# Release Notes
Since the LTT software is composed on many individual parts, the changelog specifies in which part the change/fix took place by preceding each entry with a prefix. The used prefix are:
* GUI: change took place in the LTT-GUI part of the LTT software
* MesVis: change took place in the MesVis-GUI or in the measurement recording subsystem part
* TS: change took place in the TestStand / LabVIEW subsystem part of the LTT software
* HistoryConv: change took place in the History Converter Tool
* MDBS: change took place in the MDBS database installer
***
### \[3.6.0] - 08.05.2025
{% hint style="info" %}
**Attention**
When using the IRS.LTT.Installer, a new version of MDBS gets installed. When using the IRS.LTT.Updater, the
\
existing MDBS will be kept. The new MDBS comes with new versions for MySQL database server and Apache webserver. Measurements recorded with old MDBS cannot be processed with new MDBS and vice versa. A backup of the old MDBS will be kept. For help on this topic contact IRS support.
