Version 3.0.0-beta - 2024-08-20

This version is a major one and is breaking some usage compare to v2. Read the migration guide from the documentation: https://bluebrain.github.io/HighFive/md2home2runner2work2highfive2highfive2doc2migrationguide.html

The minimum version for C++ has been moved to C++14.

Removed

- Removed `read(T*, ...)`, use explicit `read_raw(T*, ...)` for `Slice` or `Attribute`. (#928)
- Removed `FixedLenStringArray`, use any container with strings instead. (#932)
- Removed `FileDriver` and `MPIOFileDriver`, use file access properties instead. (#949)
- Removed default constructor for `Group` and `DataSet`. (#947, #948)
- Broadcasting have been removed. Use `squeeze` and `reshape` feature instead. (#992)

https://github.com/bluebrain/highfive - v2.8.0

Important Change

Eigen::Matrix is (by default) stored with column-major index ordering. Under certain conditions Eigen::Matrix was written and read as row-major. Due to code duplication H5Easy isn't affected by this bug. Starting 2.8.0 HighFive will now throw an exception whenever prior versions would have read with incorrect assumptions about the index ordering. (#731)

Implement creation of hard links (#765). Thanks to @Quark-X10.
Get the size of file and amound of tracked unused space (#764). Thanks to @Quark-X10.

Add a top-level header to include all compononents (#818).

Improvements

Add parallel HDF5 test in CI (#760).
Simplify github workflow (#761).
