Release Notes
Fledermaus 7.8.9
August 16, 2019


  • Qimera 2.0.0 had a bug that could cause issues with coordinate system selection in Fledermaus 7.8.x.  Installing and running Qimera 2.0.1 should resolve the issue.
  • FMGT 7.9.0 and FMMidwater 7.9.0 have been updated to use the new QPS Geodetic Package (3.0.0).
  • FMGT and FMMidwater now have their own installers, and are no longer included with the Fledermaus installer.
  • Fledermaus 7.8.9 still uses the previous version of the QPS Geodetic Package (2.0.3) to work with Qinsy geodetics, though the new version will work as well.
  • Fledermaus is now compatible and able to build PFM v6.40.
  • Fledermaus 7.8.0 and newer uses a new Licensing system. Purple HASPs will need updating, all other forms will need to be replaced by a Softlock.
  • Only the Windows versions of FMGT 7.9.0, FMMidwater 7.9.0, and Fledermaus 7.8.9 are available at this time.  Mac and Linux versions coming soon!
