## [v0.2.0](https://github.com/supermethodhq/ex_stl/tree/v0.2.0) (2026-01-07)



### Fixed



- Time-series decomposition ordering - Series are now automatically sorted into chronological order before decomposition

- Series validation - Added validation requiring at least 2 full periods before attempting to fit

- MSTL `seasonal_lengths` validation - Now validates that:

  - Values are at least 3 (minimum period length)

  - Values are odd numbers (required by STL algorithm)

  - Series contains enough samples for the specified seasonal lengths

- Updated module docs and added specs
