-Fix to_tsquery() and websearch_to_tsquery() to properly parse certain discarded tokens in quotes (Alexander Korotkov)
+Fix to_tsquery() and websearch_to_tsquery() to properly parse query text containing discarded tokens (Alexander Korotkov)
-Certain discarded tokens, like underscore, caused the output of these functions to produce incorrect tsquery output, e.g., websearch_to_tsquery('"pg_class pg"') used to output '( pg & class )
-<-> pg',but now outputs 'pg <-> class <-> pg'.

-Change password_encryption's default to scram-sha-256 (Peter Eisentraut)
+Change the default of the password_encryption server parameter to scram-sha-256 (Peter Eisentraut)
Previously it was md5. All new passwords will be stored as SHA256 unless this server variable is changed or the password is already md5-hashed.
+Also, the legacy (and undocumented) boolean-like values which were previously synonyms of md5 are no longer accepted.

-Allow VACUUM to eagerly add newly deleted btree pages in the free space map (Peter Geoghegan)
+Allow VACUUM to eagerly add newly deleted btree pages to the free space map (Peter Geoghegan)
Previously it had to match the collation of the partition key.

+Improve the performance of updates/deletes on partitioned tables when only a few partitions are affected (Amit Langote, Tom Lane)
+
+
+This also allows run-time pruning of updates/deletes on partitioned tables.

-The new pg_hba.conf keyword "clientname=DN" allows comparison with non-CN certificate attributes and can be combined with ident maps.
+The new pg_hba.conf keyword "clientname=DN" allows comparison with certificate attributes beyond the CN and can be combined with ident maps.

-Allow subscripting of jsonb (Dmitry Dolgov)
+Allow subscripting of JSONB and simplify the implementation of subscripting (Dmitry Dolgov)
-Subscripting can be used to extract from and assign to jsonb documents.
+JSONB subscripting can be used to extract from and assign to JSONB documents. Extensions and built-in data types can now implement subscripting more easily.
