Hi Werner, We are still working on defining the way we want to release it so I can't really say anything yet, but we'll try to have it released incrementally so that you can benefit from new features as early as possible.
I can point you to my branch on github (based on HDF5 trunk): https://github.com/soumagne/hdf5/tree/topic_indexing You can have a look at test/index.c or test/query.c To enable FastBit support, turn on HDF5_ENABLE_FASTBIT_SUPPORT for CMake or pass the --with-fastbit option if you use configure. We'll also soon distribute the corresponding RFC.
