Download the Latest Version of HDF5

HDF5 1.14 is the recommended branch to use if you need the latest high-performance computing features or the virtual object layer (VOL).

HDF5 1.10 can be used where 1.14's features are not required.

Alternative HDF5 Branches

The 1.12 API includes an early version of the virtual object layer (VOL). Now that the updated VOL interface has been released in HDF5 1.14.0, it will be retired in the spring of 2023 as the VOL layer is not suitable for pass-through VOL connectors.

HDF5 1.8 is an older version of the library that was retired in early 2023.
