- Added technique T0067 "Plan to discredit credible sources" to TA02
- Added technique T0068 "respond to breaking news event" to TA02
- Added technique T0069  "respond to active crisis" to TA02
- Added technique T0070 "Analyze existing communities" to TA02
- Added technique T0071 "Find echo chambers" to TA13
- Added technique T0072  "Segment audiences" to TA13
