Another CVE issue to be updated with a link. If that's the standard going forward, more of these CVE issues will probably appear in entry titles from currently unmerged PRs that don't yet list them this way.

It was an editorial choice I made that perhaps I regret. Should I mention this to others to add the link? I can also keep an eye on this as code freeze approaches.

I'd say it's worth bringing up. We can also do a last editing pass near to the release as well.

We can revisit your comments from this PR after we have a release branch.
| The versions of `h5cc`, `h5fc`, `h5c++`, etc. generated by CMake were missing several options and features from the Autotools counterparts. Some of these options and features have now been implemented in the CMake versions, while some of them have not: | ||
| - The missing `--help`/`-h`, `-c`, `-echo`, and `-shlib`/`-noshlib` options have been implemented. | ||
| - The `-prefix` option was not implemented, as it didn't appear to function in the Autotools wrappers and is generally covered by pkg-config in the CMake wrappers. | ||
| - A new `-nohl` option has been added to avoid building and linking against the high-level HDF5 libraries if desired. |

HDF5 libraries, if desired.

| Note that support for a native FP8 datatype has not been added yet. This means that any datatype conversions to/from the new FP8 datatypes will be emulated in software rather than potentially using specialized hardware instructions. Until support for a native FP8 type is added, an application can avoid datatype conversion performance issues if it is sure that the datatype used for in-memory data buffers matches one of the above floating-point formats. In this case, the application can specify one of the above macros for both the file datatype when creating a dataset or attribute and the memory datatype when performing I/O on the dataset or attribute. | ||
|
|
||
| Also note that HDF5 currently has incomplete support for datatype conversions involving non-IEEE floating-point format datatypes. Refer to the 'Known Problems' section for information about datatype conversions with these new datatypes. |
