Bug Fixes

• Don't mark partition rebalance complete if some partitions are not moveable (e.g. due to partial recovery mode) by @ztlpn in #18518

• #18460 rpk: ability to transfer partition leadership by @daisukebe in #18461

Bug Fixes

• Fix initial_leader_epoch/KIP-320 handling in fetch requests. It was ignored until now which prevented consumers to correctly detect suffix truncation. For Redpanda (and Raft), this is a minor problem since suffix truncation is a very improbable event. by @nvartolomei in #17728

• #18282 #18566 Fix a scenario where list_offset with a timestamp could return a lower offset than partition start after a trim-prefix command. This could lead to consumers being stuck with an out-of-range-offset exception if they began consuming from an offset below the one which was used in the trim-prefix command. by @nvartolomei in #18599
• #18282 #18566 Fix an edge case where a timequery returns no results if it races with tiered storage retention and garbage collection. This is important at least for consumers that fall behind retention. They interpret such response as the partition is empty and jump to the HWM instead of resuming consuming from the first available message. by @nvartolomei in #18599
• #18443 Fixed an assertion triggering in a full-disk scenario by @andijcr in #18444

• Fix a scenario where list_offset with a timestamp could return a lower offset than partition start after a trim-prefix command. This could lead to consumers being stuck with an out-of-range-offset exception if they began consuming from an offset below the one which was used in the trim-prefix command. by @nvartolomei in #18281
