 ## New Plugins
 - `3dveins`: reinstated for v50, this plugin replaces vanilla DF's blobby vein generation with veins that flow smoothly and naturally between z-levels
 - `zone`: new searchable, sortable, filterable screen for assigning units to pastures
+- `dig`: new ``dig.asciiwarmdamp`` overlay that highlights warm and damp tiles when in ASCII mode. there is no effect in graphics mode since the tiles are already highlighted there
 
 ## Fixes
 - Fix extra keys appearing in DFHack text boxes when shift (or any other modifier) is released before the other key you were pressing
