Publishing soon

[rconan]

I have some crates that depends on being able to parse the attributes of some HDF5 dataset , this functionality is only available in git not in the version 0.7.1 on crates.io , is there going to be a new version published soon?, I cannot published my crates until then or I will have to make a copy of hdf5-rust and publish it

@aldanor I could spend some time on getting 0.8 out the door, although I would need push rights to both the repo and crates.io
