The fixes for feature request #6 (disabling LTP screening by default) and bugs #17-#20 (broken admin functions, alarming message from ACS, fragment construction error, child process can't write to log file) will be integrated into ION version 3.2.0, but in the meantime here's a patch that implements all of those fixes within version 3.1.2. To apply the patch:
1. Download omnibus-3.1.2-a.patch from here.
2. Copy it into the ion-open-source top-level directory.
3. cd ion-open-source
4. patch --unified -Np1 < omnibus-3.1.2-a.patch
5. Then remake.
