v24.2.25

Bug Fixes

• Allow partition balancing to opearte in case when space management was enabled, but local target capacity was unset. by @ztlpn in #26305
• Enable TCP keepalive for cloud storage connections. by @Lazin in #26410
• Fix Redpanda crash if partition_autobalancing_concurrent_moves was set to 0. by @ztlpn in #26305
• When Tiered Storage is paused and data is allowed to expire from local storage there will be gaps between last offset in tiered storage and first offset in local storage. If local storage was truncated in the middle of a segment (i.e. time based retention or via trim-prefix/delete records commands) tiered storage might get stuck with the following exception: Failed to schedule upload: std::runtime_error (ntp {kafka/foo/0}: log offset N is outside the translation range (starting at M > N)). Fix this by adjusting upload start offset to the first available and valid offset. Although we might have a bit more data in the segment, other information about that data (i.e. offset translation) is gone with prefix truncation. by @nvartolomei in #26064
• partition_autobalancing_mode=off now stops on-demand partition rebalance as well. by @ztlpn in #26305
