v2.0.1

• Added one additional surname to cluster 'Brádach'
• Updated the XSL to bring the inflection of female 'adj-ach' surnames into compliance with what grammar books say about such surnames.
• Corrected a bug in the XSL which caused some initial mutations in expanded.xml to not be marked up correctly. They are marked up correctly now.

v2.0.0

• Number of surname clusters inscreased from 664 to 1,049.
• New version comprises 3,170 surname forms.

• New major source consulted for new clusters: Muhr, K. & Ó hAisibéil, L. (2021) The Oxford Dictionary of Family Names of Ireland. Oxford: Oxford University Press.
