  now running at 250 ps resolution (owners of older models with 
  1 ns resolution can request a quote for a hardware upgrade to 250 ps)

What's New in Version 2.0
 
- Some minor bugfixes 
- A new file format. The idea is to place individual header data items not 
  in a strict file position and order but to tag the items by name, so that 
  future additions do not harm existing software. 
- A new device driver in order to meet new driver signing requirements imposed 
  by Microsoft. The new driver can now be conveniently installed by setup exe. 
  Note that Windows versions prior to 7 are no longer supported. If you must 
  use an older Windows version you can still use the driver of the TimeHarp 
  260 release version 1.1. 
- Supports a new hardware feature to change the dead time of the input 
  channels for suppression of some detector artefacts. Note that this works 
  only for TimeHarp 260 P purchased after April 2015. Old boards can be 
  updated but must be returned to PicoQuant for a hardware modification.
