OpenSlide binary build 4.0.0.12 released

[Benjamin Gilbert]

Hi all,

OpenSlide binary build 4.0.0.12 has been released, fixing a regression
in build 4.0.0.10 that returned uninitialized data in the bottom tile
row of non-JPEG, non-JP2K TIFF levels.  Most slides don't have these,
but e.g. generic tiled TIFFs with LZW compression were affected.
Build 4.0.0.12 also updates various dependencies.

openslide-bin 4.0.0.12 is available for download under the terms of
the GNU Lesser General Public License, version 2.1.  If you installed
OpenSlide binaries with pip, you can upgrade with `pip install
--upgrade openslide-bin`.  The binaries are also available from the
OpenSlide website:

Thanks,
