Every document accessible from this page is the latest adopted version of its specification.
Some specifications here are totally new, the result of an adoption process that has just completed.
Others are here because they are revisions to adopted specifications. Revised specifications, where they exist, always supersede the formal version of a specification. When this happens, the preliminary version is de-listed from this page. So, if the specification you are looking for is not listed on this page, then its formal specification is the latest version. However, RTF reports for some specifications contain only a set of changes or edits that need to be applied to the previous formal version.
