HackMD Community
Published notes now appear in the HackMD Community, a shared space where public notes are discoverable by topic. Publishing a note sets its Read permission to Everyone (your original setting is restored if you unpublish), while Write permission always stays as you configured it. Notes in Public teams are published by default; switching the team to Private unpublishes them.
You can now bring Markdown content into HackMD more easily from Overview. Upload one or multiple Markdown files at once, move existing notes into HackMD faster, and keep working with the file formats you already use.
