Added a new configuration parameter shardman.silk-flow-control that controls the mode of handling read events. It has three possible values: none, round_robin, and shortest_job_first.

Added the shardman.pg_stat_foreign_stat_bytes view that shows the amount of statistics for foreign relations transferred over the network between Shardman cluster nodes. Also added the corresponding global view shardman.gv_stat_foreign_bytes.

Added a new configuration parameter shardman.sync_cluster_settings that enables cluster-wide synchronization of configuration parameters set by user.

Added a new configuration parameter shardman.sync_cluster_settings_blacklist that excludes the options not to be propagated to a remote cluster.

Added a new configuration parameter enable_sql_func_custom_plans. If enabled, custom plans can be created to run SQL functions. Enabled by default for the new clusters and disabled for the old ones.

Fixed a bug that previously resulted in shardmand hanging in case an etcd cluster looses quorum.

Allowed ALTER COLUMN SET STATISTICS for global and sharded tables.

Introduces the limitation for the privilege management per columns that is not supported for global tables.

Introduced a limitation that global tables cannot inherit other tables.

Removed the limitation for using of DEFERRABLE constraints for global tables that is now allowed.

Added a new field CSNXidMap_last_trim to the shardman.pg_stat_csn view that shows when the most recent shardman.trim_csnxid_map() function was called.

Added the shardmanctl psql command that creates a connection to the first available master node if no options are specified. If --shard is specified, the connection is installed with the shard current master.

Enabled the lz4 compression method for the default_toast_compression.

Fixed a bug that previously resulted in a failure of the shardmanctl probackup checkdb command when a custom port was specified in Shardman configuration.

Fixed a shardmand bug that previously resulted in the application failing with PANIC-level error in case of insufficient access rights to the DataDir directory.

Fixed a bug that previously resulted in primary server switching to a replica after restart. Also, added a new option --no-wait to the shardmanctl restart command (disabled by default).
