Changelog

v1.15.0 (unreleased)

Image.from_array() default changed from transpose=True to transpose=False. The old default silently transposed array data to match a legacy column-major convention inconsistent with the C++ library. Passing transpose=True explicitly now raises a DeprecationWarning.
Image.matrix_size now returns the header's (x, y, z) tuple. Previously returned (z, y, x) from the data array shape, inconsistent with the header and the C++ API.
requires-python bumped to >=3.10 (@dataclass(kw_only=True) in the xsdata-generated schema code requires 3.10+).

ismrmrd.util: new module with sign_of_directions, directions_to_quaternion, and quaternion_to_directions (all three available at the top-level package).
AcquisitionHeader and Acquisition gained channel-mask methods: isChannelActive, setChannelActive, setChannelNotActive, setAllChannelsNotActive (matches C++ ISMRMRD_ChannelMask).
ProtocolDeserializer gained peek() and peek_image_data_type() for non-consuming look-ahead.
ProtocolSerializer/ProtocolDeserializer handle CONFIG_FILE (ID 1) and CONFIG_TEXT (ID 2) message types.
ismrmrd.__version__ exposed via importlib.metadata.

Waveform.setHead() called non-existent active_channels field; corrected to channels.

xsdata-generated schema files committed to the repo; no longer regenerated at install time. Run python setup.py generate_schema to update them.
CI (both PyPI and conda workflows) now fails fast if committed schema files diverge from a fresh regeneration.
requirements.txt removed; dev setup: pip install -e ".[dev]".
Python version matrix added to CI (3.10, 3.11, 3.12, 3.13).
dependabot.yml added for monthly pip and GitHub Actions updates.
Bumped xsdata to 26.2 (>=26.2 runtime, ==26.2 dev/codegen pin); regenerated schema code (xsdata 26.2 no longer emits redundant "required": True in field metadata — no behavioral change for this library).
