Previously, false theta functions were only known to exhibit quantum
modular transformation properties. Recently, Bringmann and Nazaroglu
discovered new modularity properties of false theta functions by using
parallels to the study of indefinite theta functions and mock modular
forms. I will discuss these developments and present generalizations to
higher rank cases by Bringmann, Milas, Nazaroglu, and myself.
