## [0.19.2](https://github.com/statrs-dev/statrs/compare/v0.19.1...v0.19.2) - 2026-08-26

### Added

- Support alloc-backed APIs in no_std ([#403](https://github.com/statrs-dev/statrs/pull/403))

### Fixed

- Finish large beta edge handling
- Preserve asymmetric beta tails
- Preserve beta values near one
- Handle extreme beta tails
- Handle beta log boundaries
- Stabilize large beta CDF
- ensure special cases evaluate only for exact inputs
- ULPs comparisons should only regard ULPs in prec module
- guard LogNormal::pdf on both ends and fix ln_pdf for extreme x
- keep the left tail of LogNormal::pdf
- Preserve gamma PDF accuracy
- use frexp for evaluating ln(a*b)
- preserve NaN for Gamma pdf(0) when rate is infinite
- Stabilize gamma PDF evaluation
- restore full precision to erf's interval constants
- Update kdtree and KDE radius
- accumulate central moments relative to the first observation
- compute FisherSnedecor pdf in log space for large freedoms
- Unblock release-plz
- make Geometric cdf(1)/inverse_cdf(p) exact and portable
- correct Geometric::inverse_cdf against its definition
- compute Hypergeometric pmf in log space for large populations

### Other

- Allow beta tail rounding
- update prec ULPs docs for clarity around use case
- Assert directly in test_pdf_left_tail instead of collecting failures
- Cover frexp edge cases
- *(gamma)* small suite for rate*x near 1 cases
- *(doc)* clippy
- *(online)* guidance/suggestion for `merge`
- build the OnlineMoments offset tests under no_std
- Source large-freedom pdf fixtures from mpmath instead of SciPy
- *(deps)* bump actions/checkout from 4 to 7
- drop overexplanation implementation

## [0.19.1](https://github.com/statrs-dev/statrs/compare/v0.19.0...v0.19.1) - 2026-08-11
