### Builds after release 0.12.0
|
||||
|
||||
#### Build 2104211
|
||||
|
||||
- Replace default TV simulator effect with the version that saves 18k of flash and appears visually identical
|
||||
|
||||
#### Build 2104210
|
||||
|
||||
- Added `tb` to JSON state, allowing setting the timebase (set tb=0 to start e.g. wipe effect from the beginning). Receive only.
