This version of c9 fixes serious issues with 5.2.136 which can make all terminals unable to start c9. Requiring reinstall of c9 on affected terminals

It also includes fixes to Honda API integration. C9 is working with Honda actively to migrate API to a different system they prefer. The work isn't complete yet but part of that work was incorrectly included in last weeks recent c9 updates; meaning Honda API was effectively broken.
