This release contains performance and documentation enhancements as well as bug fixes and new features, including ...
- For replication, periodically prints progress bar, throughput metrics, ETA, etc, to the same console status line (but not to the log file), which is helpful if the program runs in an interactive terminal session. The metrics represent aggregates over the parallel replication tasks. Example console status line:
2025-01-17 01:23:04 [I] zfs sent 41.7 GiB 0:00:46 [963 MiB/s] [907 MiB/s] [==========> ] 80% ETA 0:00:04 ETA 01:23:08
- Fix shutdown for the case where bzfs_reuse_ssh_connection=false
- --delete-dst-datasets: With --recursive, never delete non-selected dataset subtrees or their ancestors.
- Improved latency if there's only a single dataset to replicate over SSH
- Parallel performance: use better heuristic to choose num-datasets-per-thread
- Also run nightly tests with final release of zfs-2.3.0
