I've been using ArgyllCms 1.5.x to make printer profiles, and been generally happy with them.  (Thanks Graeme)

ver 1.6.0 was released in Aug, 2013, and then ver 1.6.1 released in late Sep, 2013.

I'm wondering if people with more experience and expertise than myself on evaluating printer profiles have compared the 1.5.x vs. 1.6.x printer profiles and found differences. Better? About the same? Worse? No change?

Hello,
You could reconsider to rebuild your print profiles made with v1.5.0 to v1.6.0 only if you was using the ColorMunki spectro in strip mode,
because, as visible in my past  threads
http://www.luminous-landscape.com/forum/index.php?topic=82133.0
http://www.luminous-landscape.com/forum/index.php?topic=82171.0
there was a bug in chartread resulting in poor reading on blacks and some colored patches.

The practical effect I noticed in my case was a black point shifted to purple, so a color cast in the deep shadows grays.

Whether or not this occurred in your profiles is to be seen,
and the need to remake the profiles is based on how much 'picky' you are regarding this aspect that could be not so easy to spot in real prints without a measurement device.

V1.6.1 release fixed this bug, as visible in the changelog and as per what I have confirmed in my latest posts of the above threads (changing the title of the thread accordingly).

I hope this could be useful.

Ciao.

Isn't it amazing? Just one man could fix his open source profiler in just a couple of days after (probably) just one e-mail.

I wish X-Rite had just a little bit of his supernatural powers...

I wish they just had natural powers to code and debug their software in a somewhat functional manner. Or to concentrate on functionality that aids users, not themselves and in the process, cases all kinds of issues (I'm referring to XRD or X-rite Device Services).

What about model names that make sense instead of aiming to confuse, and designing a website that actually makes me want to purchase their stuff?

Yes, that's a bit of a mess but that's probably marketing. I could live with that if their process of software development were a tad more functional and speedy. Their color engine and science is great as is their hardware.

Hello,
Graeme was very effective indeed and I'm the first to confirm that he made an amazing job.
 
That said, he can confirm that it was not 'just one e-mail' from my side:
in these days I have tested something like 6 different consecutive beta releases of the chartread exe in the way to support him to iron out the issue, and for each release every time I have performed extensive test, data statistics, graphs and shared analysis and comments, including the ColorPicker comparisons with chartread various modes (strip/spot, high res or not, single or averaging etc etc...).
I'm not here to say that I have big merit, but at least I will let you know that for this task I have involved some dozen of research/test working hours for sure...

In any case I agree with you, it's amazing, I really think that his commitment is absolutely invaluable,
and all the Argyll users should really be very grateful to Graeme Gill for his efforts.

Ciao,
