UpdraftPlus Premium 2.24.3.26

FEATURE: Added the abilty to create and restore Incremental Backups (Premium version)
FIX: Work around an issue with 'SSH2 Server Host Key Algorithm Mismatch' occurring with the current phpseclib release by temporarily reverting to an earlier one
TWEAK: Improve performance by aggregating separate SQL SELECT queries (previously one for each backup) when loading the settings page
TWEAK: internal backup extradata parameter to prevent unwanted PHP notices
TWEAK: Fork a method UpdraftPlus_Filesystem_Functions::unzip_file() to allow for future enhancements
TWEAK: Periodic purging of obsolete job data that didn't get cleaned when expected was not happening on multisite
TWEAK: Improve logging when the initial call to jobdata_set_multi fails
TWEAK: Any stored backup/restore progress log files will now be deleted after 40 days. (Since they are attached to email reports, you can keep and retrieve them from those if needed). Over-ride this with the filter updraftplus_log_delete_age if desired.

FIX: a method call on an incorrect class which caused a fatal error

TWEAK: For Premium users with grand-fathered lifetime updates (i.e. purchased before August 2013), a regression had caused support entitlement expires to no longer be notified
TWEAK: For Premium users with who have downgraded from unlimited licenses to another package, a licence expiry message could show when in fact the real situation was that they just needed to specifically allocate a licence to the site. The relevant message has been adjusted to improve this.
TWEAK: Track “more files” incremental backup locations
TWEAK: Don’t show individual add-ons that have not been bought in the account add-ons page if the user has Premium.
TWEAK: Include the raw updates check response information in the internal/advanced dump
TWEAK: Added the UpdraftClone video
