Our release strategy involves short development cycles allowing for frequent releases of the app throughout the year. Major releases tend to occur about once a year with maintenance updates occurring more often.
The last major release was 5.0.1 which occurred in Nov. of 2015. Since then the focus has been on bug fixes and small updates to improve the performance and functionality of that version. No major release is scheduled for 2016 as of yet and the focus continues to be improving the functionality of the 5.x version.
