We would like to propose a no-no-vote on the changes made since the first vote. There was some concern that there are a lot of changes based on the number of files changes in the PR. I wanted to emphasize that we had to create a new pull request to address
the merge conflicts that were created after several new chapters and sections were merged. As a result, the new PR includes several changes that were already made in the original PR. The actual differences between the two versions are not that many and most
of these changes are editorial. I have listed the explicit changes made since the first vote below (these changes are also highlighted in the PDF file above):<br>

<div><br>
</div>
<div>2. addition of the following sentence in Section 2.5.8:</div>
<div>"Even though the \type{MPI\_Count} type is large enough to encode address locations, \type{MPI\_Count} type shall not be used to represent an \mpitermni{absolute address}\mpitermindex{addresses!absolute}."</div>
<div><br>
</div>
<div>3. delete the following sentence that was repeated:</div>
<div>"The support for large count and displacement in Fortran is available when using newer \MPI/ Fortran bindings \code{(USE mpi_f08)}."</div>
<div><br>
</div>
<div>4. embiggen MPI_TYPE_GET_ENVELOPE and MPI_TYPE_GET_CONTENTS</div>
<div><br>
</div>

paragraph</div>
<div><br>
</div>
<div>(b) addition of "(e.g., in constructors of MPI datatypes that can be used with files)" to the end of third bullet</div>
<div><br>
</div>
<div>(c) addition of the following new text:</div>
<div>For the large count versions of three datatype constructors, MPI_TYPE_CREATE_HINDEXED, MPI_TYPE_CREATE_HINDEXED_BLOCK, and MPI_TYPE_CREATE_STRUCT, absolute addresses shall not be used to specify byte displacements since the parameter is of type MPI_COUNT
instead of type MPI_AINT (see Section 2.5.8).</div>
<div><br>
</div>
<div>(d) addition of "MPI_Offset for parameters that represent byte displacement in files, " in the C bindings description</div>
<div><br>
</div>
