The description of this part is really confusing.
Recording file history to database for fast access is enabled by default for ‘Markdown, .txt, ppt, pptx, doc, docx, xls, xlsx’. To disable the feature or to modified the file list, you can add the following settings to seafevents.conf
[FILE HISTORY] enabled = true suffix = md,txt,...
After enable the feature, the old histories version for markdown, doc, docx files will not be list in the history page.
After reading it, I don’t know if setting enabled=true will enable the feature or disable the feature.
