GRanDMA Update


2026.03.30: The April 2026 edition of the GRanDMA genealogical database, GM26-04, is out.

2026.04.15: One of the database servers has intermittently been running quite slow. I have reverted to a previous revision of the database and am watching performance.

Steps to upgrade the database server are underway. -- KLR
