Hi All Every time EasyEDA saves a file, a history will be automatically generated. There are 10TB data files which causes huge database fees. Actually most of the historical records are useless, so we will delete the historical records on November 12, 2018. After that each document will only save the latest 10 historical records. To create a project version manually is recommended If you need to save the history version.
