Changes¶

The document records all past pytask releases and what went into them in reverse chronological order. Releases follow semantic versioning and all releases are available on PyPI and Anaconda.org.

Unreleased¶

#743 adds the pytask.lock lockfile as the primary state backend with a portable format and documentation. When no lockfile exists, pytask reads the legacy SQLite state and writes pytask.lock; pytask build continues updating the legacy database for downgrade compatibility.
#787 makes the attributes field mandatory on PNode and PProvisionalNode, and preserves existing node attributes when loading entries from the data catalog.
#744 Removed the direct dependency on attrs and migrated internal models to dataclasses.
#766 moves runtime profiling persistence from SQLite to a JSON snapshot plus append-only journal in .pytask/, keeping runtime data resilient to crashes and compacted on normal build exits.
#776 clears decoration-time annotation_locals snapshots after collection so task functions remain picklable in process-based parallel backends.
#788 updates debugger interaction tests to support Python-version-specific pdb stepping behavior and avoid frame-specific assumptions on repeated breakpoints.

#726 adapts the interactive debugger integration to Python 3.14’s updated pdb behaviour and keeps pytest-style capturing intact.
#732 fixes importing packages with missing __init__.py files.
#739 closes file descriptors for the capture manager between CLI runs and disposes stale database engines to prevent hitting OS file descriptor limits in large test runs.
#734 migrates from mypy to ty for type checking.
#736 updates the comparison to other tools documentation and adds a section on the Common Workflow Language (CWL) and WorkflowHub.
