PostGIS 2.5.1 was released on November 18th 2018 and I finished off packaging the Postgis 2.5.1 windows builds and installers targeted for PostgreSQL EDB distribution this weekend and pushing them up to stackbuilder. This covers PostgreSQL 9.4-11 64-bit and PostgreSQL 95-10 (32bit).

Note that PostGIS 2.5 series will be the last of the PostGIS 2s. Goodbye PostGIS 2.* and start playing with the in-development version of PostGIS 3. Snapshot binaries for PostGIS 3.0 windows development are also available on the Postgis Windows download page. These should work for both BigSQL and EDB distributions.
