                  - hipi-pud utility added to support setting of PUD resistors
                  - set_pud method added to all HiPi::Pin modules allowing
                    setting of pull up / pull down resistors from usercode.

    Version 0.28  - 23 April 2013
                  - bug fixes for HiPi::Device::GPIO::Pin

    Version 0.27  - 08 April 2013
                  - Using second I2C channel on P5 now tested and supported
                  - HiPi::BCM2835::I2C now supports per-instance transfer rates
                  - hipi-i2c utility extended to support en/disable of i2c buses
                  - GPIO PAD 5 documentation and GUI App display had 3V3 and 5V0
                    pins reversed.

    Version 0.26  - 23 March 2013
                  - Bug in HiPi::BCM2835::I2C->set_baudrate caused peripheral 1
                    value to always be set regardless of peripheral specified.
                  - Added i2c_write_error / bus_write_error to allow case where
                    i2c error condition expected. e.g. when a device has a
                    sofware reset and does not complete the i2c transaction
                    when reset command is sent.
                  - Standardised error handling across all three i2c interfaces.
                  - HiPi::Interface::MPL3115A2 added mode, active, oversample
                    and now uses delay based on oversample rate.

    Version 0.25  - 19 March 2013
                  - fixed bug in hipi-i2c installation

    Version 0.24  - 19 March 2013
                  - Added hipi-i2c command line utility to allow none Perl code
                    access to i2c commands.
                  - All calls to external programs ( cat, echo etc. ) are now
                    taint safe.
                  - Installation now always does an apt-get update before
                    apt-get install (depedency list). My test builds
                    often fail at dependency installation time if apt-get update
                    is not executed.

    Version 0.23  - 18 March 2013
                  - bug in i2c C code fixed.

    Version 0.22  - 17 March 2013
                  - Added i2c interface to HiPi::Device::I2C (in addition to SMBus)
                  - Added HiPi::BCM2835::I2C - i2c using registers direcly
                  - Added HiPi::Interface::MPL3115A2 - to demonstrate repeated
                    start operation using HiPi::BCM2835::I2C
                  - Updated all i2c using interface modules to accept smbus, i2c
                    or bcm2835 backends

    Version 0.21  - 12 March 2013
                  - HiPi::Device::OneWire read bug fixed
                  - PWM Pin setting fixed in Control App
