New Feature

Setting lock_object_storage_task_distribution_ms to improve cache locality with swarm cluster. (#866 by @ianton-ru)

Improvements

Allow data and metadata with different paths. Support S3 tables as a warehouse. (#860 by @ianton-ru)
This changes the default behavior of partition pruning for Iceberg table. (ClickHouse#80583 by @melvynator via #881)
Added support of compressed metadata.json files for Iceberg. (ClickHouse#81451 by @alesapin via #883)

Bug Fix (user-visible misbehavior in an official stable release)

IcebergS3 supports count optimization, but IcebergS3Cluster does not. As a result, the count() result returned in cluster mode may be a multiple of the number of replicas. (ClickHouse#79844 by @wxybear via #878, #885)

Build/Testing/Packaging Improvement

Fix branding (#870, #871, #886 by @Enmk)
