; by Martin Bujdak, microHAM
--------------------------------------------------------------------------------

v2.0, released 071122
  - Some changes in keyer protocol and settings format was introduced to be
    compatible with router v5.1.0. Hence firmware MUST be upgraded and power-up
    settings MUST be again stored to EEPROM of keyer.
  - Firmware utilizes extended frequency/mode information from router CAT
    decoder:
    - Keyer mode follows TX mode.
    - Any of RX, TX, operating, VFO A or VFO B frequency can be displayed.
    - CI-V can report any of those frequencies too.
  - bug fixed: Sleep mode was permanently enabled regardless of settings.
  - BackSpace on PS2 keyboard now functions as ESC.
v1.2, released 071017
  - serious bug fixed: Under some circumstances a data sended from computer
    to keyer could be lost. It caused various undesirable keyer behavior
    (incorrect PTT configuration, incorrect WK commands, lost data for WK, ...)
  - bug fixed: PS2 keyboard/pad sporadically freeze in state in which it didn't
    respond to key strokes.
  - CW output is allowed only in CW mode.
  - PTT from paddle is generated only in CW mode. WinKey command "PTT On/Off"
    still can be used to generate PTT in non CW modes.
  - bug fixed: When DVK message was started from Control protocol the message
    "PLAYING MSG x" stay displayed on MK2 display even message was finished.
    The same for recording.
