Infrastructure

Postgresql 12 / 16
- PostgreSQL 12 will reach EOL on November 14, 2024 and FOLIO needs to transition to a current version, PostgreSQL 16. Quesnelia will be a transition release which must run under both PostgreSQL 12 and PostgreSQL 16, this will allow deployed environments to transition.
- See DR-000038 - PostgreSQL Upgrade to 16
OpenSearch 2 / Elasticsearch 8 – (OpenSearch maintenance policy) (Elasticsearch support policy, EOL dates, release history)
Kafka
S3/MInIO

Support period

Technology versions must support the full Quesnelia support period that ends around December 2024: Quesnelia will be released in April 2024 and will be supported until Sunflower (R3 2024) gets released around December 2024 (based upon assumption that future releases will follow a similar cadence to previous releases), see FOLIO support policy.
