* Fixed very small potential memory leak.
* Improved handling of cancelled IR Irps.
* Significantly improved IR Receive handling.
* Custom IR Receive handling supported.
* Improved IRBlasting for 'finicky' settop box receivers.

Driver Release 7.6.1.27118 (4/28/09)
* Brookville support including ATSC.
* 8993 Support.
* 88A1 and 89A1 no longer support IR.
* Support for new 8891 and 8991 IR SubIds.
* Turn off Blaster LEDs on resume from sleep.
* Fix obscure CIR bug.
* Fixed issue which caused problems for SageTV and simultaneous recordings.
* Fixed issue which under some circumstances could allow an Analog Tune to fail with "blue screen video".

Driver Release 7.6.1.27076 (3/17/09)
* QAM HRC fixed.
* Turn off Blaster LEDs on Driver Load.
* CIR Receive Buffer sizes increased.
* CIR Blasting improvement.
* CIR Handshake disabled by default.  Won't interfere with pre-existing CIR implementations on Vista.
* Disable support for old "C1" prototype boards.  Driver will load.  No tuner support.
* Fix both Analog and Digital "First Tune" Issues.
* Fix bad interaction between [digital] tuners.  Sometimes digital tuner would receive errors on tune from other.
* Initial Support for Crossbar Flexibility.
* Extend Digital Cable (QAM) tuning range up to channel 158 (max had been 125).
  NOTE that this does not mean that every channel will be received well as that range can be questionable by broadcaster and tuner alike.
* Fix "Analog Blue Video on Digital Tune" issue.  Sometimes analog video would go blue if the other tuner were tuned digitally.
* Fix MCE "FirstRun" detection of ATSC.

Driver Release 7.6.1.27023 (1/23/09)
* SECAM AM Audio Fix.
* Appropriate CIRCoInstaller Support in INF for Vista and later.
* ATSC/QAM tuner sensitivity improvements.
* 64Bit OS "greater than 4G" memory issues resolved (black/green screen issues).
* Support for "EnableAutoOffset" reg patch.
  This improves situation for Australian users whose signals are re-broadcast on non-centered frequencies
  but whose streams report the original (way off) frequency.
* Failure on "First Tune" resolved.
* Support for the hcwWilt_RegisterAdapterObject_ registry patches.
  The "Std" version fixes a Microsoft Bluescreen on some 64Bit [Dell and potentially other] machines which bluescreen under some circumstances.
  This is NOT a Hauppauge bug and unfortunately we are presently powerless to detect this situation dynamically.
  But this registry patch will resolve the issue.
* TDA10048 SNR fixes and efficiency improvements.
* QAM Suppport on Fiji/Win7 by default.  Overrideable via reg key.
* Introduce 888x, 88Ax, 898x, and 89Ax models for programming.

Driver Release 7.3.0.26198 (07/16/08)
* hcwECP BitRateMode issues fixed.
* SoftJumper implemented.
* New Wiltshire/Halesite Models supported.
* Fix for IR Priority Receive issue.
* Remove support for obscure formats.
* Works with WinTV and Digital Sources (Improved Digital Transport Buffer negotiation).
* Analog HRC support.

Driver Release 7.2.9.26105 (04/14/08)
* Encoder Property Page cleanup
* Variable Bit rate mode improvements
* picture quality improvement for YPbPr input
* Close Caption decoding improved (stability)
* Arcsoft TotalMedia TV application supported
* FM Frequence range extended: 65MHz to 108MHz (demanded in Russia)
* Performance tuning support enabled
* Improved IR Support.
* Improved multiple board support.
* VBI Data Level corrected, was too high.
* Hibernation performance improvements. 
* The limit of the peak bitrate for VBR was set to 9.5MBit in the driver, average bitrate still at 6Mbit 
* Sliced VBI has no more effect on stability of RDS 
* Fix PowerOn initialization of tuners.
* Fix VideoDecoder GetParameter call so it correctly returns any failures (it was pretty much always return OK even if there were a failure).  This is as yet untested.
* VISTA ONLY... Remove extra unnecessary and problematic "QAM" tuner instance.
* Support for QAM_AS_ATSC.
* Support for AltTSFormat (problematic).

Driver Release 7.1.22.26025 (01/25/08)

* Signal Monitor supported on 8901 and 8800.
* Access to more than 2 generic devices now possible
* XP64 analog issue resolved.

* Eliminate duplicate check for default video standard.
* Improved registry support in driver.
* Improved I2C handling for multiple devices.
* Forced Firmware download fixed.
* Firmware Filename can be overriden from registry.
* ProductionTest drivers MUST specify firmware filename.
