What

Two changes affect project documents:

  • Updating a document can now send a fingerprint of the content the edit started from. The fingerprint is a SHA-256 hash, a short code calculated from the text.
  • Reading a project can now return a version for what was read.

Previously, an update sent only the new content.

Why

This lets an edit notice when the document changed after it was read, so one change does not silently overwrite another.
