@@ -2802,11 +2802,23 @@ non-backward compatible changes introduced in the 4.0 release:
* Writable slaves do not propagate writes to their sub-slaves, so writes to
writable slaves remain just local.
* The RDB format changed. Redis 4.0 is still able to read 3.2 (and all the
past versions) files, but not the other way around.
* Certain log formats and sentences are different in Redis 4.0.
* Certain INFO fields, especially related to replication, are now different.
* GEODIST, GEOPOS and GEOHASH return values changed for non existing keys:
Previously the return value was inconsistent between non existing key
and non existing elements. Now the return is always like if the key
contains no elements if the key does not exist. So, for instance,
"GEOHASH non_existing_key A B C" now returns an array of 3 NULL values
as it should. In general this change should not break compatibility with
the past since in the past two different forms were provided by the server
and the new behavior is one of the two.
