  The master_preferences files has been moved from /usr/share/chromium to
  /etc/chromium to support system level configuration of default options.

chromium-browser (69.0.3497.100-1) unstable; urgency=medium

  All local extensions that are installed to /usr/share/chromium/extensions
  will now be loaded and enabled automatically.

  Some extension packages used to do this manually with a file in
  /etc/chromium.d. This conflicts with the new approach, so those packages
  need to be updated to account for this.

  External extensions were enabled by default in an upload prior to the
  release of stretch and will remain this way for the buster release.  A
  future upload following the release of buster will disable this.

chromium-browser (55.0.2883.75-4) unstable; urgency=medium

  External extensions are now disabled by default.  Chromium will only load
  extensions that are explicitly specified with the --load-extension command
  line option passed into CHROMIUM_FLAGS.  See the chromium-lwn4chrome
  package for an example of how to do this.

  You can also use the --enable-remote-extensions command line argument to
  chromium, which will bypass this restriction.
