The Changelog is as follows:
Changelog RC3: (Update Version with IYUV Codec)
1.2 / 1.3 (08/02/2016)
Modified I420 Codec for IYUV Colorspace (same as I420) and added
the "iyuvvfw.dll" Codec for both Versions.

The I420 Codec upsamples to YUY2 if the IYUV codec is selected and
is meant to work this Way.

The IYUV Codec now reports itself as "Helix IYUV YUV Codec" again
instead of "Helix IYUV 420 Codec".

Fixed decoding Intel I420/IYUV Videos (32/64 Bit) with the Helix
Codecs and works both ways now for encoding and decoding.

Fixed decoding Drastic YCbCr I420/IYUV/YV12 Videos (32 Bit) with
the Helix Codecs and works both ways now for encoding and decoding.

Fixed decoding Arksoft IYUV and ATI YV12 Videos (32/64 Bit) with
the Helix Codecs for encoding and decoding.

Fixed Problems with Empia/Afa/SynTek and other Capture Drivers.

Fixed Problems with Osprey/ATI/Matrox/Intel/Aurora/DVS/Aja and
other popular Videoboards.

Fixed Problems with the Phillips MoviePlus and PixelPlus Drivers.

Fixed Problems with LogiTech and other Webcam Drivers.

Solved minor Problems with HonesTech HDV Encoder, MainConcept,
Craaft Cinema, Cinegy, Cyberlink, Microsoft and Pegasus encoders.

Solved Problems with the FourCC Codec install Order in the Registry.

Solved Problems with DirectX, Direct Draw, Active Movie, Direct2D,
Direct3D and OpenGL FourCC Mapping from I420 to IYUV and conforms now
to the Microsoft White Paper for YUV Formats in Windows.

The new INF-File restores the native 32 Bit Windows Codecs if the
Helix Codecs are uninstalled and removed from the System.

Other 64 Bit Codecs for I420/IYUV/YV12 are no longer replaced by
the Helix Codecs and can co-exist now with the Helix Codecs.

The Helix Codecs can now co-exist with the Drastic Codecs if the User
installed the Drastic YCbCr Codecs and the Helix Codecs afterwards.

Note:
If you install the Helix Codecs first and afterwards the Drastic Codecs
then the Helix Codecs are DISABLED ! Remember, first the Drastic Codecs
and THEN the Helix Codecs.

Other Fixes:
The Problem with the original EXE-Version was, if the User removed
the Helix Codecs from the System the original Codec for I420 was
not restored and has been fixed in this Release.

I have updated the 1st post in this thread with the archive's ReadThis.txt (with some edits to make it fit within the forum's 16,000 character post size limitation). The download link is the same as before.
