* Implement support for complex number datatypes Adds the new datatype class H5T_COMPLEX Adds the new API function H5Tcomplex_create which creates a complex number datatype from an ID of a base floating-point datatype Adds the new feature check macros H5_HAVE_COMPLEX_NUMBERS and H5_HAVE_C99_COMPLEX_NUMBERS Adds the new datatype size macros H5_SIZEOF_FLOAT_COMPLEX, H5_SIZEOF_DOUBLE_COMPLEX and H5_SIZEOF_LONG_DOUBLE_COMPLEX Adds the new datatype ID macros H5T_NATIVE_FLOAT_COMPLEX, H5T_NATIVE_DOUBLE_COMPLEX, H5T_NATIVE_LDOUBLE_COMPLEX, H5T_CPLX_IEEE_F16LE, H5T_CPLX_IEEE_F16BE, H5T_CPLX_IEEE_F32LE, H5T_CPLX_IEEE_F32BE, H5T_CPLX_IEEE_F64LE and H5T_CPLX_IEEE_F64BE Adds hard and soft datatype conversion paths between complex number datatypes and all the integer and floating-point datatypes, as well as between other complex number datatypes Adds a special conversion path between complex number datatypes and array or compound datatypes where the in-memory layout of data is the same between the datatypes and data can be converted directly Adds support for complex number datatypes to the h5dump, h5ls and h5diff/ph5diff tools. Allows h5dump '-m' option to change floating-point printing format for float complex and double complex datatypes, as well as long double complex if it has the same size as double complex Adds minimal support to the h5watch and h5import tools Adds support for the predefined complex number datatypes and H5Tcomplex_create function to the Java wrappers. Also adds initial, untested support to the JNI for future use with HDFView Adds support for just the H5T_COMPLEX datatype class to the Fortran wrappers Adds support for the predefined complex number datatypes and H5Tcomplex_create function to the high level library H5LT interface for use with the H5LTtext_to_dtype and H5LTdtype_to_text functions Changes some usages of "complex" in the library since it conflicts with the "complex" keyword from the complex.h header. Also changes various usages of the word "complex" throughout the library to distinguish compound datatypes from complex datatypes.

Please refer to the release_docs/INSTALL file for installation instructions.
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 information about The HDF Group, the HDF5 Community, and other HDF5 software projects, tools, and services at The HDF Group's website.

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.
