Sorry, I went into detail about the part you went
into detail about, which was using the ACR 4.4 profile in the new ACR versions
and it wasn't clear what the question was, other than hoping Tom would keep his
script up-to-date, which he hasn't been.
If your question is about whether to update
the jsx code to think 4.4.1 is supported, yes, go ahead. I have had to do
this with every release of ACR since Tom does not do it in a timely manner,
anymore.
ACRC being compatible with a particular version of
ACR mainly means it understands how to reset the various sliders that aren't
part of the calibration process (Clarity, Vibrance, Split Toning, Linear Toning
Curve, etc) to their zero or default values and there is a potential for a
new ACR version to have new sliders and even have old sliders removed, and
without a compatibility review for each new version of ACR the script might
either miss resetting newly added sliders or accidentally try to reset sliders
that no longer existed.
The good news about the versions of ACR since Tom
released his last update in January, is that the ACR sliders didn't change since
then, so you can merely update the code to include the newest version of
ACR in the list of supported versions and run fully
compatible.
The bad news is that there are several places to
update the version number, but when he added support for 4.2 and 4.3.1 to the
January version, he missed two of the three places, so while the script seemed
to be compatible, it was really not, meaning it doesn't reset any of the sliders
to zero or defaults and you have to do it, yourself.
Since you are comfortable updating the code,
double-click on the jsx file (from Windows Explorer) to open it in the
ExtendScript Toolkit editor, search for "4.1" and
add the current version of ACR to the supportedVersions array initializer list
in the three places you find it (just after lines 100, 400 and 450). If
you search for 4.3.1 you will only find one place, and all three places need
updated, as you can tell by looking at the comments.
Back in January I sent an e-mail to Tom about 2 of
the three places being missed, and he agreed it was a bug, but said he was on
the road so couldn't fix it immediately, and now its June and still the bug
remains.
From using the Lightroom 2.0 beta, it is clear ACR5
will have some more things to reset--at least the localized
dodge/burn/saturation paintbrush, so the current script won't be resetting
everything it should, but as long as you reset things, yourself (perhaps with a
Preset), you could update the code so it thinks its compatible and have it reset
most things, still.
I am also suspicious the camera calibration may be
changing where Photoshop and Lightroom and may support automated calibration
and/or ICM files, where scripts like Tom's may be obsolete or at least need
extensive revision. My suspicion is based on comments by Adobe insider
Jeff Schewe a couple months ago:
