MariaDB Foundation Newsletter – 15 October 2026
The first half of October belonged to the ecosystem. The MariaDB Ecosystem Hub passed 200 entries six months after launch, Laravel 13 gained native MariaDB Vector support through community contributors, and Frappe and Solanica joined the Foundation as Silver Sponsors. The Foundation’s testing framework learned PostgreSQL, reproduced a regression reported by Mark Callaghan and confirmed the fix, and Frédéric Descamps explained why 173 security reports in two quarters is good news. Here’s what happened.

Community Spotlight: Slava Rozhnev and SQLtest.online

AWS renewed as Diamond sponsor for a fourth year, and Kamatera and Elestio joined as Silver Sponsors. Here’s what happened.
