Hi Neel,
Support for CF 3.5 is currently underway, however I am not able to give you a definite time line for when it will be fully implemented.
Please do let me know which features of CF 3.5 you would like implemented, with details on the application you are working on, by emailing support@redfivelabs.com and we will consider making it a priority in our development plan.
Thanks,
Jaishni
