This release contains the latest beta 3 of PostgreSQL 18 and beta 1 of PostGIS 3.6.0.

For a full list of changes, please refer to the PostgreSQL Release Announcement and the PostgreSQL Release Notes.

This release updates PostGIS 3.6.0 to Beta 1 and upgrades some of its dependencies to the latest major versions. pgRouting has been updated to version 3.8, and pgvector now includes the necessary patches to run on PostgreSQL 18.

Please note that beta versions are intended for evaluation purposes only. You may encounter bugs of varying severity. During the beta testing period, the on-disk data format of PostgreSQL is not yet stable. This means that the data directory may not be compatible with future versions. You will need to dump and restore your database when upgrading from 18beta1 to 18beta3. (18beta2 and 18beta3 are compatible).

A similar caveat applies to additional extensions installed like those released in the Postgres.app Extensions repository. During the beta period, these extensions may need to be rebuilt due to changes in the internal API. Extensions built for 18beta1 are not compatible with 18beta3.

The binaries of PostgreSQL 13-17 are identical to those in Postgres.app release 2.8.5.
