v3.5.5 for N9/N950 is available here.

Changes:
- Support for WMS servers that use EPSG:3045(EPSG:32633) coordinate system that is used in Norway
- A few minor new features

Installation:
1. Download .deb file from the link above and install it.
2. Copy WMS settings file to "/home/user/MyDocs/.mapsi/" (or attach N9 to computer using mass storage mode and copy settings file to ".mapsi" folder in root (e.g. "D:\.mapsi\") (Create that folder if it don't exist) ) and rename it to "wms_settings.ini".

Note that Mapsi is a WMS client and it can use any WMS server that supports correct EPSG coordinate system. WMS settings file attached to this post is just one example of a settings file. It uses WMS servers from Lantmäteriet and Statens kartverk.
