This document summarizes the change history for the CGNS documentation. Each entry includes the document version number, the date of the change, and a (very) brief description of the change. For the Mid-Level Library, Standard Interface Data Structures, and SIDS File Mapping Manual, the CGNS release number that the document corresponds to is also shown. A bit more detail about the changes may be available in the What's New list for the CGNS documentation. Note that very minor changes and/or typo corrections may not be documented below.
To simplify things, as of V3.3, all "Document Versions" simply correspond to the "CGNS Version", so only one number is used from this point forward.
