## [Unreleased][unreleased]
### Changed
+- Improved LF manchester and biphase demodulation and ask clock detection especially for reads with heavy clipping. (marshmellow)
- Iclass read, `hf iclass read` now also reads tag config and prints configuration. (holiman)
- *bootrom* needs to be flashed, due to new address boundaries between os and fpga, after a size optimization (piwi)
### Fixed
-- Fixed issue #19, problems with LF T55xx commands (marshmellow)
+- Fixed EM4x50 read/demod of the tags broadcasted memory blocks. 'lf em4x em4x50read' (not page read) (marshmellow)
+- Fixed issue #19, problems with LF T55xx commands (iceman1001, marshmellow)
