V3.11 Minor release - Windows platform

In that release, no changes made in the bootloader.
Some timing and synchronization were made in tkg-flash, following random issues reported on Win10 platform.

Major release 3.10

tkg-hid-bootloader / tkg-flash

• Improvement in term of reliability :
  . ack were added to essential flash commands
  . firmware checksum and version verification
  . sync and timing tuned between tkg-flash and the hid bootloader

• booloader :
  . Send ack when ready to start
  . Return flash memory size, page offset
  . Support of kikpad, the Midiplus Smartpad custom firmware

• tkg-flash
  . "-info" option can be used without flashing to get current firmware infos.
  . infos always displayed , so "-info" option in flashing mode nota vailable anymore
  . hid bootloader firmware version is now checked to activate new features only if >=0X310
  . Supports of previous 2.x bootloader firmwares (but I recommend to upgrade to the 3.1 as support is short term)
  . last version of the hidapi library
