## [unreleased][unreleased]
### Added
+- `lf t55xx resetread` added reset then read command - should allow determining start
+of stream transmissions (marshmellow)
+- `lf t55xx wakeup` added wake with password (AOR) to allow lf search or standard lf read after (iceman, marshmellow)
- `hf iclass managekeys` to save, load and manage iclass keys. (adjusted most commands to accept a loaded key in memory) (marshmellow)
- `hf iclass readblk` to select, authenticate, and read 1 block from an iclass card (marshmellow)
- `hf iclass writeblk` to select, authenticate, and write 1 block to an iclass card (or picopass) (marshmellow + others)
- Added option c to 'hf list' (mark CRC bytes) (piwi)
### Changed
+- Adjusted lf t55xx dump to allow overriding the safety check and warning text (marshmellow)
+- Adjusted lf t55xx write input variables (marshmellow)
+- Adjusted lf t55xx read with password safety check and warning text and adjusted the input variables (marshmellow & iceman)
+- Adjusted LF FSK demod to account for cross threshold fluctuations (898 count waves will adjust the 9 to 8 now...) more accurate.
+- Adjusted timings for t55xx commands. more reliable now. (marshmellow & iceman)
+- `lf cmdread` adjusted input methods and added help text (marshmellow & iceman)
- changed `lf config t <threshold>` to be 0 - 128 and will trigger on + or - threshold value (marshmellow)
- `hf iclass dump` cli options - can now dump AA1 and AA2 with different keys in one run (does not go to muliple pages for the larger tags yet)
- Revised workflow for StandAloneMode14a (Craig Young)
