  ! - bug fix
  ? - known issue

--------------------------------------------------------------------------------

v3.7.0.0, 29.4.2014, Davor

  + Iex messagess sending periods made dependable of can baud rate.

--------------------------------------------------------------------------------

v3.6.0.5, 25.2.2013, Davor

  * Calibration procedure extended to accept both 10A and 20A devices.
    20A devices must be calibrated, otherwise measurements will be halved.

--------------------------------------------------------------------------------

v3.6.0.4, 20.7.2012, Davor

  * Bus_error is active when CANTEC>0 or CANREC>0 (before was >63).
  * Measurement_status error activates program_error instead of bus_error.
  * Use with CyPro v2.6.8 or newer.

--------------------------------------------------------------------------------

v3.6.0.3, 10.4.2012, Davor

  * Based on v3.6.0.1
  * Can watchdog added.
  * Iex header changed according to v2.6 specifications.

--------------------------------------------------------------------------------

v3.6.0.2, 31.01.2012, Davor (internal release)

  * Calibration extended to accept 20A devices.

--------------------------------------------------------------------------------

v3.6.0.1, 08.12.2011, Davor

  ! CAN error counters are sent once when become 0.

--------------------------------------------------------------------------------

v3.6.0.0, 06.12.2011, Davor

  ! On-site calibration with specified reference values.

--------------------------------------------------------------------------------

v3.5.0.2, 26.07.2011, Davor

  + Calibration constants protected with a complement copy. Updating PCB will
    require new calibration.
  * Variable 'slave_board_status' renamed to 'device_status', new states added.

--------------------------------------------------------------------------------

v3.5.0.1, 18.01.2011, Davor

  ! Wrong order of info messages solved.

--------------------------------------------------------------------------------

v3.5.0.0, 30.12.2010, Davor

  + Calibration for voltage, currents and pv reference.
  + Measurement error is triggered when V/f frequency is out of range.

--------------------------------------------------------------------------------

v3.4.0.2, 30.11.2010, Davor

  + CAN error counters (CANTEC, CANREC) are now exposed as bus_error_counters.

--------------------------------------------------------------------------------

v3.4.0.1, 29.11.2010, Damir

  * Bus_error is active when CANTEC>63 or CANREC>63 (before was 0).

--------------------------------------------------------------------------------

v3.4.0.0, 11.05.2010, Davor

  * Current and voltage filtering/resolution is now configurable.
  * Temperature measurements disabled when board functions as a slave.
  * Communication between left and right board changed, this version is not
    compatible with older versions.

--------------------------------------------------------------------------------

v3.3.0.1, 14.03.2010, Damir

  * Surge contact changed from normally open to normally closed.

--------------------------------------------------------------------------------

v3.3.0.0, 25.03.2010, Davor

  * Support for 3nd generation hardware (current is measured with shunts).

--------------------------------------------------------------------------------

v3.2.0.1, 18.11.2009, Davor

  * Software correction (odd/even) for magnetically induced measurement errors.

--------------------------------------------------------------------------------

v3.2.0.0, 22.10.2009, Davor

  * Support for 2nd generation hardware (currents measured with Hall sensors).

--------------------------------------------------------------------------------

v3.0.0.2, 23.4.2009, Davor

  * Voltage measurement reconstructed.

--------------------------------------------------------------------------------

v3.0.0.1, 15.4.2009, Davor

  + Surge monitoring added.
  * Voltage measurement changed, scalling added.

--------------------------------------------------------------------------------

v3.0.0.0, 6.3.2009, Davor

  + First offical release, alpha/beta releases are now obsolete.
