The "Remote options" section has been completely rewritten. As such, you will need to redo all your options in this section after upgrading. If you don't, remote uploads will fail, and possibly produce errors.
BackBlaze has been added as a remote upload option!
Dropbox has been added as a remote upload option!
Fixed an issue related to Guzzle duplication in XF2.1.
While this addon really has no issues with this announcement. I felt it would probably be wise to mention it in this update. If you are having issues related to the announcement, you can simply add --default-character-set=utf8mb4 to the "MySQL options > Custom dump options" field in the options for this addon. I have also made this the default setting for this field for future installers.
This addon will no longer re-open your board after running a backup, if your board was closed originally. It will retain the open/close setting of your board at the time the backup began.
Added a few explanations for the Amazon S3 fields in the options to help people figure it out.
Added an option to automatically delete older backups based on a numerical retention limit.
Added the ability to do automatic remote uploads via FTP to another server after backup. This process happens AFTER the forums have been re-opened, so it should not add any extra download to your website. Only backup files themselves are uploaded; not any log files. These remote uploads are not subject to the new retention limit option.
