Version 1.2.1 (2025-08-10)

This is a minor patch with bug fixes, minor changes, and documentation improvements.

Bug Fixes

Allow quant_reg with tol=inf to only perform one fit, since it was previously impossible
to recreate the output of quant_reg by inputting weights since it required one inner loop.
Allow a smooth_half_window of 0 for mormol to skip smoothing rather than raising an
exception in order to be consistent with other methods.

Set the default of normalize_weights to False for airpls to match its literature
implementation; will deprecate the keyword in version 1.3.
For 2D Whittaker-smoothing algorithms, a ValueError is now raised when num_eigens is
less than or equal to diff_order, which has the same effect as inputting lam=0 and
is also not allowed. Previously just emitted a warning.
Slightly sped up several functions used for setting up and solving penalized splines.
Only calculate method signatures when their corresponding functions (eg.
pybaselines.polynomial.modpoly) are called rather than immediately upon importing pybaselines.
Should slightly improve import timings.

Added an example for using masking with the various types of algorithms in pybaselines.
Made all example programs in the documentation able to be ran without cloning the repository.
Added back API documentation which was removed in version 1.2.0 for the functional interface of
pybaselines. The functional interface is now marked as legacy rather than pending deprecation.
