Version 0.3.9 (Latest)
----------------------

**Release Date:** May 2026

Bruker loader refactor (cyclomatic complexity 60 and 89 split into small
private helpers), full type annotations on ``eprload()``, explicit
imports in ``epyr/__init__.py``, NumPy docstrings with worked examples
on 53% of the public API, and tooling fixes (``make format`` and
``make quality-fix`` both return 0). See :doc:`release_notes/v0.3.9`.

Version 0.3.8
-------------

**Release Date:** April 2026

Documentation-quality release with a fitting-module refactor and CLI
output fixes. ``epyr.lineshapes.fitting`` split into focused private
helpers; public API unchanged. See :doc:`release_notes/v0.3.8`.

Version 0.3.6
-------------

**Release Date:** February 2026

Maintenance release: dead-code removal, test-API alignment with the
lineshape refactor, ``plot_2d_waterfall`` ``clip_factor`` option, and
``.flake8`` tuning. See :doc:`release_notes/v0.3.6`.

Version 0.3.5
-------------

**Release Date:** February 2026

Analytical Voigt derivatives via Faddeeva-function identities, pseudo-Voigt
derivative and phase support, matplotlib 3.8+ compatibility for
``plot_2d_map`` and ``vmin``/``vmax`` color scale control. See
:doc:`release_notes/v0.3.5`.
