## [unreleased][unreleased]
### Added
+- Added lf gproxii read - reads a gproxii tag from the antenna
- Added lf indala read - reads an indala tag from the antenna
- Added lf visa2000 demod, read, clone, sim commands (iceman)
- Added markers in the graph around found Sequence Terminator after askmandemod.
- Added option c to 'hf list' (mark CRC bytes) (piwi)
### Changed
+- `data askgproxiidemod has been moved to `lf gproxii demod` (reads from graphbuffer)
- `lf indalaclone` has been moved to `lf indala clone`
- `lf indalademod` has been moved to `lf indala altdemod` (reads from graphbuffer)
- `data pskindalademod` has been moved to `lf indala demod` (reads from graphbuffer)
