## [0.1.9] - 2017-02-27
- fix warning about return in readButton8()

## [0.1.08] - 2016-05-20'
-  Merged work of Septillion
- Fix/refactor ButtonRead8() - see https://github.com/RobTillaart/Arduino/issues/38
- missing begin() => mask parameter

## [0.1.07] - 2016-05-02  
- (manually merged) Septillion
- added dataOut so a write() doesn't read first,
   possibly corrupting a input pin;
- fixed shift comment, should read 1..7;
- added begin() to be sure it's in a known state,
  states could be different if uC is reset and the PCF8574 isn't;
- added buttonRead() and buttonRead8()
  which only effect the output while reading

## [0.1.06] - ??
- (intermediate) added defined errors + refactor rotate

## [0.1.05] - 2016-04-30
-  refactor, +toggleMask, +rotLeft, +rotRight

## [0.1.04] - 2015-05-09
- removed ambiguity in read8()

## [0.1.03] - 2015-03-02
- address int -> uint8_t

## [0.1.02] - ?
- replaced integers with uint8_t to reduce footprint;
- added default value for shiftLeft() and shiftRight()
- renamed status() to lastError();

## [0.1.01] - ?
- added value(); returns last read 8 bit value (cached);
  value() does not always reflect the latest state of the pins!

## [0.1.00] - 2013-02-02
- initial version
