Although we have been referring to this since last year, we have been unable to make progress, but we are working on adding an automatic backup function in the event of a critical bug.
We are also working on other minor bugs in parallel, but we will continue to update without notifying you except for important bug fixes.
(We plan to publish a list of fixed bugs when we have finished the interim update.
(The silent update of the backup process will continue for a few days)
