Highlights of the changes in this release:
* Implemented fully the _Change records_ tab for item and holdings record changes.
* Changed the lookup tab to have a checkbox controlling whether only open loans are searched, or whether all loans are searched.
* Changed the lookup tab to have a checkbox controlling whether the FOLIO inventory API or the storage API is used to get records.
* Revised the order of the tabs to put "lookup records" first, as this seems like a more useful default.
* Slightly revised the user interface layout of some of the tabs.
* Fixed system tray widget for macOS.
* Fixed various bugs throughtout.
* Rewrote various internal functions for (hopefully) better clarity and logic.
