Collabora Online developer edition 22.05 released

CODE
22.05 has been released; this is the 'developer edition' of the
Collabora Online offering formerly known as LibreOffice Online.

CODE 22.05 is preceding the next major release of our long-term
supported business suite Collabora Online. This free developer
version includes all features and enhancements that will be
available in our enterprise version, expected later in July. The
CODE releases allow every interested user to learn and test new
features on an early stage.

New features include support for external grammar checkers, the ability to
have 16,000 columns in a spreadsheet (which is evidently useful to
somebody), sparkline plots, support for WebP graphics, and more.
