I ran this on both versions on fresh instances / clusters with the data
from a previous run :

\timing on
CREATE TABLE gist_fastbuild(pt point);
COPY gist_fastbuild FROM '/tmp/gist_fastbuild.copy';
CREATE INDEX ON gist_fastbuild USING gist (pt);
VACUUM ANALYZE gist_fastbuild;
\di+ gist_fastbuild_pt_idx
EXPLAIN (ANALYZE, BUFFERS) SELECT pt FROM gist_fastbuild WHERE pt <@
box(point(.5,.5), point(.75,.75));

I get the same results as before.
