Aurora PostgreSQL Gets Fresh Updates Across Five Versions
Amazon Aurora PostgreSQL-Compatible Edition now supports five new minor versions (18.6, 17.11, 16.15, 15.19, and 14.24) packed with community bug fixes and Aurora-specific improvements. You can roll out these updates smoothly using automatic minor version upgrades and AWS Organizations policies to test on non-critical databases first.
