Thank you for your comments.
Please note that RM in the develop branch is a superset of RM for all previous releases and current maintenance branches. We plan to provide snapshots of the code and post updated documentation with every snapshot from the develop branch. Therefore, HDF5 users will have access to the updated documentation on a regular basis.
We also plan to merge documentation to the 1_12 maintenance branch and it will be available in the HDF5 1.12.1 release planned for May 31, 2021. At this point we don’t have time estimate for moving documentation to the 1_10 and 1_8 maintenance branches and corresponding releases. This will not be a straight forward task since code diverged and merges will need some work. We think our efforts should focus on making the rest of our documentation (e.g., User’s Guide, Tech Notes, File Format, etc.) searchable and maintainable.
We hope that by moving RM to Doxygen it would be easier for the community members to contribute and make HDF5 documentation better. We welcome and appreciate all contributions from spelling and grammar fixes to better explanation of the functions, code examples, etc.
