Hello!
After NoteCaddy update to v. 2.6.0.14 (HM 2.0.0.8673) I reset my notes and most of my custom note definitions stopped working. In NoteCaddy pop-up I see some error instead of my notes and also I tried to reimport these notes to NoteCaddy and got message that they are not valid note definitions. Interesting fact that these notes I've been using for a long time and they also were correctly imported and work now in new HM3 NoteCaddy beta.
After downgrading to NoteCadde 2.6.0.12 everything works correct.
I attach one custom note definition as an example.
