This repository contains a high-performance library's source code and a file format

specification that implements the HDF5® data model. The model has been adopted across

many industries, and this implementation has become a de facto data management standard

in science, engineering, and research communities worldwide.

The HDF Group is the developer, maintainer, and steward of HDF5 software. Find more

RELEASE SCHEDULE

----------------

![HDF5 release schedule](doc/img/release-schedule.png) 

HDF5 does not release on a regular schedule. Instead, releases are driven by

new features and bug fixes, though we try to have at least one release of each

maintenance branch per year. Future HDF5 releases indicated on this schedule

are tentative.

| Release | New Features |

| ------- | ------------ |

| 2.0.0 | Drop Autotools support, drop the HDF5 <--> GIF tools, add complex number support, update library defaults (cache sizes, etc.), use semantic versioning |

| FUTURE | Multi-threaded HDF5, crashproofing / metadata journaling, Full (VFD) SWMR, encryption, digital signatures, sparse datasets, improved storage for variable-length datatypes, better Unicode support (especially on Windows) |

NOTE: In the March 2025 release we will begin using semantic versioning (https://semver.org/) and the previously announced 1.16.0 version will instead be numbered 2.0.0.

[A list of planned HDF5 2.0 features and bugfixes can be found here.](https://github.com/HDFGroup/hdf5/wiki/HDF5-2.0-Planning)

This list of feature release versions is also tentative, and the specific release

in which a feature is introduced may change.
