Dear Orthanc community,

In addition to the [release of Orthanc 1.12.7](https://discourse.orthanc-server.org/t/orthanc-1-12-7-oe2-1-8-2-authorization-plugin-0-9-1/), I am pleased to announce that version 3.2 of the whole-slide imaging plugin is also available.

This maintenance release brings the following improvements:

- Added support for more transfer syntaxes in the Web viewer plugin, including JPEG-LS.
- The `OrthancWSIDicomizer` command-line tool can now generate JPEG-LS instances with argument `--compression=jpeg-ls`.
- Support windowing if rendering grayscale images using on-the-fly deep zoom (check out [this discussion](https://discourse.orthanc-server.org/t/orthanc-wsi-plugin-quirk/5609)).
- Added tolerance to imaged volume width/height by looking only at the finest level (check out [this discussion](https://discourse.orthanc-server.org/t/wsi-display-issue-with-orthanc-api-imagedvolumeheight-and-imagedvolumewidth-missing/5689)).
- The photometric interpretation of JPEG2000 images generated by `OrthancWSIDicomizer` has been fixed to the correct value `RGB`.

Kind Regards,  
Sébastien-
