Changelog

This page lists changes since Working Draft 3.

Since WD 4

• Removed URI from Report, and replaced reason with tags.
• Docs now use the term "Transient Entity" where appropriate.
• Mandated Unix-style \n line endings in all text fields.
• Renamed the following headers, as per RFC 6648:
  • X-Signature to Versia-Signature
  • X-Signed-By to Versia-Signed-By
• Removed the nonce from the signature system, replaced with Versia-Signed-At (timestamps).
• Standardize rate limits with IETF draft draft-polli-ratelimit-headers-02.
• Properly documented Group federation and subscribing.

  • The Note group field documentation has been updated to reflect this.

• Switched from ISO 8601 to RFC 3339 for timestamps.
  • In most cases, the two are interchangeable, but RFC 3339 is more strict. Most implementations should not need to change anything.

  • Changed all Collections that can contain remote entities to use URI Collections (eg. User collections.followers).
