oiiotool new command: --pastemeta takes two images as arguments, and
appends all the metadata (only) from the first image onto the second
image's pixels and metadata, producing a combined image. #2708
TIFF: Fix broken reads of multi-subimage non-spectral files (such as
photometric YCbCr mode). #2692
Python: When transferring blocks of pixels (e.g., ImageInput.read_image()
or ImageOutput.write_scanline()), "half" pixels ended up mangled into
uint16, but now they use the correct numpy.float16 type. #2694
Python: The value passed to attribute(name, typedesc, value) can now be
a tuple, list, numpy array, or scalar value. #2695
IBA::contrast_remap() fixes bug that could crash for very large images
#2704
Warn about recommended minimum versions of some dependencies.
Windows fix: correct OIIO_API declaration on aligned_malloc, aligned_free
of platform.h. #2701
Fix oiiotool crash when --resize was used with multi-subimage files. #2711
Bug fix in Strutil::splits and splitsv: when input is the empty string,
the split should return no pieces. #2712
Support for libheif 1.9. #2724
TIFF: Fix spec() and spec_dimensions() for MIPmapped TIFF files, they
did not recognize being asked to return the specs for invalid subimage
indices. #2723
TIFF: add ability to output 1bpp TIFF files. #2722
