If you are using Google Drive with shared drives (including any G Suite drives except the one owned exclusively by your Google user account) you will have to set up a self-hosted OAuth2 helper in one of your sites, and use it with your backup profile's configuration. This is due to a change on Google's side.
Self-hosted OAuth2 helpers. You can now use your own installation as the OAuth2 helper for Box.com, Dropbox, OneDrive, and Google Drive integration instead of the helpers provided by our company. IMPORTANT! You will HAVE to do that if you want to use shared drives in Google Drive, as noted above.
Alternate Configuration page saving method which doesn't hit maximum POST parameter count limits. Our backup profile configuration page has gone over 100 individual configurable parameters. When this is submitted back to the server, it would trigger the maximum POST parameters limit in a stark minority of servers which expect 100 or less of these parameters. We are now using client-size JavaScript code to serialise the configuration to JSON before submitting it to the server as a single, fairly small JSON document, therefore overriding the observed issue.
ShowOn in the System Configuration page. Settings in the System Configuration page which only make sense to display when another setting has a specific value will now be automatically shown when needed, and hidden from view when they are irrelevant and inactive.
Bug fixes and minor improvements. Please take a look at the CHANGELOG below.
