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.

Other Changes

• 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.

Documentation/Examples

• 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.
