Release of OMERO 5.4.1

Jean-Marie Burel (Staff)
Dear all,

Today we are releasing OMERO 5.4.1, a bug-fix release.

Improvements include:

  *   labeled zoom slider bars in the UI to differentiate from horizontal  scrollbars and make clear thumbnails can be zoomed (including Plate and Well thumbnails)
  *    fixes for installation walkthrough documentation - installation of script dependencies and gunicorn, and clarification of which user account to use for "pip install" actions
  *   fixed checking of "guest" user
  *   update to fetch third-party artifacts over https to allow OMERO to build even without a local Maven cache already populated
  *   added javax.activation dependency to allow OMERO.insight to work with Java 9
  *   import of files reporting extreme pixel sizes now fail rather than hanging
  *   pyramid-making now aborts when a tile fails
  *   various test fixes
  *   CLI fixes:
     *     improved help output for graphs commands to make it clearer that "--include" and "--exclude" expect class names not object IDs
     *     allowed setting the ``OMERO_PASSWORD`` environment variable instead of using the "-w" command-line option
     *     made passwords hidden by default when running "omero config get"
     *     fixed the CLI metadata tablestest plugin to not use an empty list of Columns

This release also upgrades the version of Bio-Formats that OMERO uses to 5.7.2  - see
