Version: OpenSim 0.9.1.0 Snail Release (SIMULATION/0.3 - SIMULATION/0.8)
Downloaded and tested this version today with the original search, profile and money modules compiled with 0.9.0.0 (running on linux with mono 5.10.1.47) and at least for me they seem to work fine. Note: I used the zip file of the binary packages. Both (*.zip and *.tar.gz) should actually be same, but as far as I remember the zip file was compiled with windows while tar.gz was compiled with some linux.
jOpenSim v0.3.1.5 throws a deprecated warning when communicating with the modules. This is actually not an error but sure should be solved in the next version. Until then I recommend to disable all warnings and deprected messages via error_reporting.
Please dont hesitate to report here if you run into a different experience when updating.
