 # v1.2
 
-- Add mode selection
+- Major changes to default behavior:
+  - If time is not specified, whatever mode is selected will run until the vacuum gets low on battery. Then it will go home.
+  - If a time is specified, vacuum will run until the end of elapsed time then it will stop in place.
+- Addition of a mode flag:
+  - `-m quiet`: Automatic direction, low suction
+  - `-m default`: Automatic direction, medium suction
+  - `-m max`: Automatic direction, maximum suction
+  - `-m edge`: Stick to the edges of the room
+  - `-m spot`: "Spot clean" - goes in goes in a spiral from one point
+- Addition of a status flag:
+  - `-s or --status` will connect to robovac and print status.
+- Improve tuya logs and callbacks by associating status names with their values.
+  - whereas before, status indicators such as "power" and "work mode" were reported as numerical keys, the keys are now just called "power" and "work mode".
+- add a return to base flag
+  - `--return or -r`: when combined with `--time or -t`, will instruct robovac to return to base after time has elapsed. (default is to pause in place when time elapses).
+  - This is semantically different from `-b or --home` because it only impacts a timed job.
