version 4.12 build 34  (October 4, 2012)
------------------------------------------------------------
- DD4: Add support for new PROD string 7721DD4-HD+VGPI 
- DE4: fix for not bypassing AFD properly (not frame accurate)


version 4.11 build 12  (December 16, 2011)
------------------------------------------------------------
- Added support for 720p/50 video 
- Fixed writing AFD Embed Line to FPGA.

version 4.09 build 7  (October 5, 2011)
------------------------------------------------------------
- DD4: added splice_insert_type to dynamic trigger list for SCTE104
- DD4: added SCTE104 GPO triggering timing functionality. Now in addition to hold duration we can have a delay (before GPO active) as well. Both delay & hold time can   be based on local settings, or use pre_roll_time & break_duration from Splice Request Data.

Verified against:
7700FC 3.07 Build 2
DE4 Jar: 142
DD4 Jar: 112

version 4.08 build 15  (January 17, 2011)
------------------------------------------------------------
DE4:
- Channged the default state of SCTE104 insertion controls for each GPI to enabled, so after upgrade the firmware behaviour is the same.

Verified against:
7700FC 3.06 Build 1
DE4 Jar: 142
DD4 Jar: 108

version 4.08 build 14  (January 10, 2011)
------------------------------------------------------------
DE4:
- Added the ability to enable/disable SCTE104 insertion based on individaul GPIs
- Fixed passing of TC for non-GPI version of the card for HD
DD4:
- Added trap when SCTE104 is received. Varbindings contain MSG#, and GPO# if triggered.

7700FC 3.06 Build 1
DE4 Jar: 142
DD4 Jar: 108

version 4.07 build 27  (October 28, 2010)
------------------------------------------------------------
- Added support for different timestamp with time_type = 3 for SCTE104 inserter
- Added Static/Dynamic GPO triggers based on SCTE104 packet contents.  This allows users to carry GPI triggers from the 7721DE4-HD+SCTE104 all the way thru to the 7721DD4-HD+SCTE104
- Added global GPO mode support
