The PostGIS development team is pleased to release PostGIS 2.5.0alpha. This release is a work in progress, and some features are still slated to be added. Although this release will work for PostgreSQL 9.4 and above, to take full advantage of what PostGIS 2.5 will offer, you should be running PostgreSQL 11beta+.
Best served with PostgreSQL 11beta which was recently released.
