Hi all,

OpenSlide Python 1.4.6 and OpenSlide Java 0.13.3 have been released,
skipping a couple version numbers due to problems with release
automation.  Mainly these releases add constants for the new
`openslide.barcode` property in OpenSlide 4.0.1.  OpenSlide Python
also has an updated OpenSeadragon and some small additional cleanups.

I've also released openslide-bin 4.0.0.14 with the last set of
dependency updates for OpenSlide 4.0.0 and a fix for CVE-2026-48977.
This release is available for anyone who isn't yet ready to move to
OpenSlide 4.0.1.

As always, all three are released under the terms of the GNU Lesser
General Public License, version 2.1, and you can download them from
the OpenSlide website:

Thanks,
