I thought software developers were meant to be a clever bunch and used
to dealing with floating point numbers etc, but they all seem to have
this crazy idea that 3.10 is greater than 3.9 somehow. Throw in some
versions like 3.16, 3.2, 3.23, and you have all manner of confusion.

.... or you missed the details on how the "#version" statement works ;)
The "#version" statement takes a FLOAT number, with the two digits after the
decimal point being interpreted as the secondary and tertiary version number,
respectively; thus, "#version 3.71" means the scene is designed for POV-Ray
3.7.1.

Which implies a version of PovRay 3.71 The version on the site is PovRay
3.7.0
An update.

What do you mean by "the site"?

One. Not a couple.
Also, did I mention that 3.7.1 is still under development? Its set of features
is not finalized yet, and the corresponding builds report as
"3.7.1-alpha.WHATEVER".
(Then again, yes - everyone still working with 3.7.0 missed a _couple_ of
_alpha_ updates.)

Funny word "couple" it can mean a small number ar well as two.

It was certainly implied but I read the groups a lot.

Of course you can specify
#version pi;
but that would be ill-advised, as it makes POV-Ray fall back to various
quirky habits of pre-3.2 POV-Ray ;)

Really wonderful! Thanks for the excellent fix to those alpha-channel 'fading'
problems. (At first, I thought the problems were still there :-( ... but then I
realized that I needed to change #version 3.7 to #version 3.71 in my scene.)
I'm a happy guy! I have several older scenes that I want to revamp with your new
fix.
