The all-in-one update
TARDISChunkGenerator and other TARDIS plugins (Weeping Angels, Vortex Manipulator...) are no longer required as separate plugins as they are now modules of TARDIS that can be enabled and disabled.
See upgrade instructions here:

Resource pack
The plugin and TARDIS-Resource-Pack have been updated to no longer use unused mushroom block states, and now use Item Display entities. More info here: https://eccentricdevotion.github.io/TARDIS/item_displays.html
To update your TARDIS console, use the Desktop Theme GUI.
