Nothing remotely interesting.
I managed to boot kernel.old from the boot loader and reverted to :

root@phobos:/usr/src # uname -apKU
FreeBSD phobos 14.0-CURRENT FreeBSD 14.0-CURRENT #4

Where the zpool is the lone NVME device in this Lenovo laptop :
root@phobos:/usr/src # zpool status
pool: c3
state: ONLINE
status: Some supported and requested features are not enabled on the pool.
The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not
support
the features. See zpool-features(7) for details.
config:
NAME STATE READ WRITE CKSUM
c3 ONLINE 0 0 0
nvd0p4 ONLINE 0 0 0
errors: No known data errors
root@phobos:/usr/src #
That is an interesting message about the zpool there.
So zpool upgrade -v says :
root@phobos:/usr/src #
root@phobos:/usr/src # zpool upgrade -v
This system supports ZFS pool feature flags.
The following features are supported:
FEAT DESCRIPTION
-------------------------------------------------------------
async_destroy (read-only compatible)
Destroy filesystems asynchronously.
empty_bpobj (read-only compatible)
Snapshots use less space.
lz4_compress
LZ4 compression algorithm support.
multi_vdev_crash_dump
Crash dumps to multiple vdev pools.
spacemap_histogram (read-only compatible)
Spacemaps maintain space histograms.
enabled_txg (read-only compatible)
Record txg at which a feature is enabled
hole_birth
Retain hole birth txg for more precise zfs send
extensible_dataset
Enhanced dataset functionality, used by other features.
embedded_data
Blocks which compress very well use even less space.
bookmarks (read-only compatible)
"zfs bookmark" command
filesystem_limits (read-only compatible)
Filesystem and snapshot limits.
large_blocks
Support for blocks larger than 128KB.
large_dnode
Variable on-disk size of dnodes.
sha512
SHA-512/256 hash algorithm.
skein
Skein hash algorithm.
edonr
Edon-R hash algorithm.
userobj_accounting (read-only compatible)
User/Group object accounting.
encryption
Support for dataset level encryption
project_quota (read-only compatible)
space/object accounting based on project ID.
device_removal
Top-level vdevs can be removed, reducing logical pool size.
obsolete_counts (read-only compatible)
Reduce memory used by removed devices when their blocks are freed
or remapped.
zpool_checkpoint (read-only compatible)
Pool state can be checkpointed, allowing rewind later.
spacemap_v2 (read-only compatible)
Space maps representing large segments are more efficient.
allocation_classes (read-only compatible)
Support for separate allocation classes.
resilver_defer (read-only compatible)
Support for deferring new resilvers when one is already running.
bookmark_v2
Support for larger bookmarks
redaction_bookmarks
Support for bookmarks which store redaction lists for zfs redacted
send/recv.
redacted_datasets
Support for redacted datasets, produced by receiving a redacted
zfs send stream.
bookmark_written
Additional accounting, enabling the written#<bookmark> property
(space written since a bookmark), and estimates of send stream sizes for
incrementals from bookmarks.
log_spacemap (read-only compatible)
Log metaslab changes on a single spacemap and flush them periodically.
livelist (read-only compatible)
Improved clone deletion performance.
device_rebuild (read-only compatible)
Support for sequential mirror/dRAID device rebuilds
zstd_compress
zstd compression algorithm support.
draid
Support for distributed spare RAID
zilsaxattr (read-only compatible)
Support for xattr=sa extended attribute logging in ZIL.
The following legacy versions are also supported:
