Versions shipped

Morphjet does not ship one version of JBIG-KIT everywhere — each platform's build channel pins its own. The archive above contains the corresponding source for every row here.

Version	Shipped in	Built from
`2.1`	`ocr/windows-x86_64`, `documents/windows-x86_64`	windows only, inside DjVuLibre's closure as engine/ddjvu/bin/libjbig-0.dll. Version is the binary's own self-description: "JBIG-KIT 2.1 -- (c) 1995-2014 Markus Kuhn". ⚠️ NOT in the images pack: that pack's IM_MOD_RL_jbig_.dll is a coder module built with no JBIG backend — it imports no jbig library and MagickCore carries none, so it creates no obligation.

Upstream project (reference only — upstream removes old releases, which is why we host the source ourselves): https://www.cl.cam.ac.uk/~mgk25/jbigkit/

The full text of the GPL-2.0-or-later license ships inside the pack (share/licenses/jbigkit) and is reproduced in the app's About screen. The version you are running is shown there too. The source stays available for as long as we distribute this build. Not legal advice.
