# crystract 1.0.1

* Refactored internal CIF extraction logic to robustly check for multiple alternative CIF tags when parsing chemical formulas, structure types, and space group names/numbers.
* Updated `README` installation instructions to include options for both stable (CRAN) and development (GitHub) releases.
* Improved the package vignette by updating Wyckoff filtering examples (from `4a` to `4d`) and adding a new section demonstrating how experimental errors are extracted from CIF loops and propagated through calculations.

# crystract 1.0.0

* Initial CRAN submission.
