FEATURE: Add support for bucket-specific application keys in Backblaze
FEATURE: Added the ability to take incremental backups via UpdraftCentral
FIX: Dropbox authorisation setting getting lost after saving UpdraftPlus settings in the free version
FIX: Issue where an error wasn't thrown if you tried to restore a backup with no valid components
TRANSLATION: Norwegian (Bokmål) and Polish translations are now complete and supplied from wordpress.org, so can be removed from the free plugin zip (saves 900KB disk space - if your mother tongue is not English and you want to improve UpdraftPlus, take a look at:
UpdraftPlus WordPress Backup Plugin < GlotPress).
TWEAK: Ride a polling status check on the regular heartbeat check, thereby reducing the need for stand-alone polls
TWEAK: If FTP settings were removed and an attempt was made to download a backup, then a zero-sized file would be created and then an unclear error shown, instead of just showing a clear error.
TWEAK: For premium users: Added the option to connect to UpdraftCentral Cloud at point of connecting a license to a site
TWEAK: If on PHP 5.3 or later, then register our Google SPL auto-loader with the 'prepend' flag, so that we can avoid loading incompatible Google SDKs registered (but not yet used) by other components
TWEAK: Clear settings visuals after wipe settings
TWEAK: Improve UpdraftPlus news layout on dashboard
TWEAK: Handle a case seen where the updates checker failed to load
TWEAK: Prevent a possible PHP notice when requesting a rating

TWEAK: The "follow this link to refresh your (licensing) connection)" (paid versions) link was not functioning
TWEAK: Alert the user in the UI if they have activated a storage destination without any settings
TWEAK: If a directory is not found during a restore but the parent directory is then, where relevant, UpdraftPlus will automatically try to create the missing directory
TWEAK: Use the correct nonce name when requesting filesystem credentials if needing the WP_Filesystem API to delete old directories
TWEAK: Regression in 1.16.6 - certain types of final errors stopped being shown in the final report and had to be read from the log file

TWEAK: Prevent the download entities UI becoming uglified from multiple button presses
