Full change log

1.1.0

Many thanks to @brtnfld, @jwsblokland, @planetmarshall and @lindstro for contributions to this release 💪

New features

• updated for ZFP 1.0.0
• decompression compatability check relaxed to compare ZFP codec version instead of ZFP library version which should result in less of a need to keep H5Z-ZFP versions in lockstep with ZFP.
• Has been tested against ZFP versions 0.5.0, 0.5.2, 0.5.4, 0.5.5 and 1.0.0 as well as cross-version read/write scenarios involving these versions.

Testing improvements

• Elim inclusion of zfp library itself in test clients (was there for compile-time version selection logic).
• Add missing calls to H5Z_zfp_finalize() for library mode testing.
• Add CI testing with GitHub actions (thank you @brtnfld 🥇)
• CI testing against ZFP 1.0.0 now.
• Handle h5repack args correctly for newer HDF5 libs
• Add example of a direct write from ZFP CFP compressed array.
• Add Windows build to CI (thank you @planetmarshall 🥇)
• Improved pass/fail reporting from make check
• Added zfp/h5z-zfp compatability tests and data files

Build improvements

• CMake build (thank you @jwsblokland 🥇)
• Improve CMake build to find zfp and hdf5 in lib64 dirs (thank you @brtnfld 🥇)
• Added generic interface fortran wrappers with tests (thank you @brtnfld 🥇)
• Get working with HDF5-1.12
• Fix handling of CFLAGS for vanilla Make
• Update for ZFP 1.0.0 (thanks to all for reviews and testing)

New Contributors

• @jwsblokland made their first contribution in #52
• @planetmarshall made their first contribution in #71

Full Changelog: v1.0.1...v1.1.0

Version 1.0.1

• Fixed incorrect compile-time version number in 1.0.0 release (very sorry to anyone who downloaded 1.0.0)
• Eliminated installation of make.vars.inc

Version 1.0.0

• support ZFP library version 0.5.5
• support ZFP lossless (reversible) mode
• support 4D ZFP arrays
• support >4D arrays w/<= 4D chunking
• Demonstrate 6D, time-varying example
• Add tool to print -f arg for controlling the filter via h5repack
• Add more tests for error conditions
• Add documentation for chunking, time-varying example and using h5repack

Bug fixes for >3D Datasets

• Fixes two critical bugs for using the filter with datasets with more than 3 dimensions.
  • potential buffer overrun issue in assessing non-unity dimensions in the chunk size
  • use of used dimensions and not chunk dimensions in setting ZFP header

Without these fixes, compression behavior for datasets of more than 3 dimensions is wholly broken.

Version 0.8.0

• Fix install of Fortran module
• Upgrade to support ZFP 0.5.2
• Add Coverage analysis in testing
• Update documentation

Fix minor build issues and zfp lib compatability issues

v0.7.0

updating help instructions

Adding Fortran Interface and Tests

v0.6.0

updating version # to 0.6.0

Bug fixes for stream flush and array dimension mixup

v0.4.0

remove H5Z-ZFP version number verbiage

Initial Release

Note: a missing stream flush call causes a bug with accuracy mode in this release. Until a new version number is incrimented and a new release cut, best to clone the master.
