Since nobody else wanted to take this on, and since I've got a bit of
leisure time, I'll have a bit of a go. There may well be things that
have fallen through the gap between when Rune stopped and I started
collecting the info.
The "unconfirmed" section at the end is there for my convenience. It's
easier for me to capture the information when I first see it rather than
waiting for a confirmation to be posted.

There are no "details". That's all the info there is. Currently no-one
knows what causes this.
: Isosurfaces *much* slower in beta 7?
: (isosurfaces with "evaluate" are now very slow)
: http://news.povray.org/3bdf24b3$1@news.povray.org
I think this one should be marked as "fixed in next beta".
There are also two other bugs/deficiencies which bother me quite a lot,
but no-one seems to notice (for some reason):
* When outputting to PNG, the wrong gamma correction value is written to it.
The value 1.0 is always written as gamma to the PNG, which is wrong. The
correct value to be written is 1.0/opts.DisplayGamma, which gives the correct
result. Another feasible solution is to not to output any gamma value at
all (I personally prefer this one) - this way PNG would work as all the
other possible output image types.
This is extremely easy to fix: In png_pov.cpp in the function
PNG_Image::PNG_Image() at lines 640-641 either comment out these two lines
(makes it to output no gamma correction value at all), or else fix the
first line to:
info_ptr->gamma = 1.0/opts.DisplayGamma;
* Focal blur aperture has no effect with camera types other than the
persective one (focal blur is calculated, but the aperture is ignored).
This one is (well, at least seems to be) easy to fix. I have discussed this
in http://news.povray.org/povray.beta-test/19382/

Thanks Mike,
Here is an old one for you that never made it in the list:
Are '&' and '|' swiched?
http://news.povray.org/Xns9128A184570B3seed7@povray.org
in the same thread: '<=' is wrong

Not absolutely sure about this one...

Thanks a lot Mike!

Here I believe the actual bug is:
(after shortening a too long blend map, POV-Ray crashes in the next render)
> Bug with parse_string
> http://news.povray.org/9pk0rto8s07dnm320f5m503aqu43ak6g3p@4ax.com
This one is not a bug.

I've just fixed this one now.
Keep up the good work! :)

While I can confirm that the bug was there (and it is fixed again now), is
it just me who is experiencing a deja vu? If change 503 on 2001/02/14 just
wouldn't say I fixed it and I would not know it was working back then...

Thorsten,
This doesn't sound good at all, I'm not trying to worry you. But maybe
you should take the dog out for a walk more often. A change of
perspective. Not stare at that rectangular glass all day....
