v0.4.0

Overview

This is a minor release rather than a patch release to signify that numpy 2 compatibility can be expected, provided that zfpy>=1.0.1 is installed. Functions deprecated in numpy 2 have been removed, but since this is a pure-Python module some environments using numpy<2.0 and zfpy<1.0.1 can also be expected to work.

What's Changed

• Remove numpy-1.x dependency restriction as zfpy and pyzgy are np-2.x compatible by @da-wad in #96

New Contributors

• @TovTyvold made their first contribution in #97

Full Changelog: v0.3.6...v0.4.0

v0.3.6

• adds use_higher_samples_precision option to StreamConverter
  • Specifies whether to use higher precision for the sample interval and sample time.
    Default is False. When set to True, stores sample interval and sample time as
    64-bit floating-point numbers for increased precision. If False, they are stored
    as 32-bit integers.

v0.3.5

• Added new StreamConverter
  • similar to NumpyConverter
  • compresses a 3D numpy array to an SGZ file as a stream of chunks
  • enables sequential compression without loading the entire array into memory
• Updated Numpy requirements to <2.0.0

v0.3.4

• Allocate space in header for floating-point sample interval + offset

v0.3.3

• Fix Publish to PyPI workflow, which needed runner version unpinning.

v0.3.2

Summary

• Bugfix for coordinate scalars coming from ZGY
• Minor performance fix
• Add Equinor boilerplate
• Upgrade dependencies to reduce vulnerabilities
