## [unreleased][unreleased]
### Added
+- `lf t55xx bruteforce <start password> <end password> [i <*.dic>]` - Simple bruteforce attack to find password - (iceman and others)
+- `lf viking clone`- clone viking tag to t55x7 or Q5 from 4byte hex ID input
+- `lf viking sim` - sim full viking tag from 4byte hex ID input
+- `lf viking read` - read viking tag and output ID
+- `lf t55xx wipe` - sets t55xx back to factory defaults
- Added viking demod to `lf search` (marshmellow)
- `data askvikingdemod` demod viking id tag from graphbuffer (marshmellow)
- `lf t55xx resetread` added reset then read command - should allow determining start
- Added option c to 'hf list' (mark CRC bytes) (piwi)
### Changed
+- Added `[l] <length>` option to data printdemodbuffer
+- Adjusted lf awid clone to optionally clone to Q5 tags
+- Adjusted lf t55xx detect to find Q5 tags (t5555) instead of just t55x7
+- Adjusted all lf NRZ demods - works more acurately and consistantly (as long as you have strong signal)
+- Adjusted lf pskindalademod to reduce false positive reads.
+- Small adjustments to psk, nrz, and ask clock detect routines - more reliable.
- Adjusted lf em410x em410xsim to accept a clock argument
- Adjusted lf t55xx dump to allow overriding the safety check and warning text (marshmellow)
- Adjusted lf t55xx write input variables (marshmellow)
