RELEASE SCHEDULE
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 C++ API, 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.
This list of feature release versions is also tentative, and the specific release in which a feature is introduced may change.
