Please see the attached tarballs, previous announcements in this forum
and INSTALL.txt for suggestions on compiling and running via wrapper script.
A reminder the yuqk fork is not POV-Ray. As time passes, it's less
likely existing POV-Ray scenes will work without modification.

---------------- povray-3.8.0-x.yuqk_ec0430bd.tar.gz April 01, 2024
yuqk R13 v0.6.7.0
Updated +-mi flag / max_image_buffer_memory ini option to allow zero
argument. An intuitive way to turn the buffering off to save memory.
Added antialias_gamma=1.0 (+ag1) and antialias_threshold=0 fast path
code to sampling method 3. The fast paths already existed in methods 1
and 2. (The color channel gamma corrections ahead of the threshold test
are relatively expensive)
Fixed a divide by zero bug in AA sampling method 3 where we end up with
a single pixel within a thread rendering block.
The reporting of pixels and samples per pixel made substantially cleaner
for Anti-Aliasing methods 1 and 2.
The upper limit for Anti-Aliasing threshold increased to 1e35 from 1.0.
Though the upper limit long at 1.0 (or a step under), the difference for
methods 1 & 2 always could be as much as four even where rgbt channel
values all with a 0-1 range. Folks often exceed the 0-1 range -
especially today with HDR environments / real light intensity renders.
The extended command line flag checking now returns errors in a way more
aligned with existing command line checking, rather than throwing an
exception.
Correcting typo in the ini name for the new Anti-Aliasing Min Depth
option, 'Antialias_Min_Depth'. Also renaming the +-rm flag form of the
command to +-rd. I was reminded - the hard way - that 'rm' is a
dangerous command in any Linux / Unix environment...
Added a +-ini<filename> command line flag as a pairing to the long
implemented but, never documented include_ini=<filename> ini file option.
Changed the create_continue_trace_log=on|off / +-cc default to off.
Changed verbose output (verbose=on|off, +v, -v) default to false.
Implemented additional command line flag checking for previously missed
specification errors.
A minor bug fix for +ec / enc_column and +er / end_row options when the
starting values defaulted.
Removed small, bounding adder around font glyphs as used in the text{}
object. The change dates back to yuqk release R8, v0.6.2.0. It was
causing problems where constructed scene elements depended upon the
returned min_extent(), max_extent() vectors of passed text{} objects or
IDs (per jr). The adder fixed clipping issues in very rare cases; user
can always manually bound those, if need be.

thanks. install + simple test went ok.
@Kurtz
attached a simple build script, to add to your collection :-); the prefix
directory and ownership etc need adjusting. hth.
regards, jr.
