The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.4.8] - 2025-11-29

• WARNING: Breaking changes!
• LassoParameters and LassoSearchParameters have a new field fit_intercept. When it is set to false, the beta_0 term in the formula will be forced to zero, and intercept field in Lasso will be set to None.

[0.4.0] - 2023-04-05

Added

• WARNING: Breaking changes!
• DenseMatrix constructor now returns Result to avoid user instantiating inconsistent rows/cols count. Their return values need to be unwrapped with unwrap(), see tests

[0.3.0] - 2022-11-09

Added

• WARNING: Breaking changes!
• Complete refactoring with extensive API changes that includes:
  • moving to a new traits system, less structs more traits
  • adapting all the modules to the new traits system
  • moving to Rust 2021, use of object-safe traits and as_ref
  • reorganization of the code base, eliminate duplicates
• implements readers (needs "serde" feature) for read/write CSV file, extendible to other formats
• default feature is now Wasm-/Wasi-first

Changed

• WARNING: Breaking changes!
• Seeds to multiple algorithims that depend on random number generation
• Added a new parameter to train_test_split to define the seed
• changed use of "serde" feature

Dropped

• WARNING: Breaking changes!
• Drop nalgebra-bindings feature, only ndarray as supported library
