v14.2.3 Nautilus
================
This is the third bug fix release of Ceph Nautilus release series. We recommend
all Nautilus users upgrade to this release. For upgrading from older releases of
ceph, general guidelines for upgrade to nautilus must be followed
:ref:`nautilus-old-upgrade`.
Notable Changes
---------------
* Nautilus-based librbd clients can now open images on Jewel clusters.
* The RGW `num_rados_handles` has been removed. If you were using a value of
`num_rados_handles` greater than 1, multiply your current
`objecter_inflight_ops` and `objecter_inflight_op_bytes` parameters by the
old `num_rados_handles` to get the same throttle behavior.
* The secure mode of Messenger v2 protocol is no longer experimental with this
release. This mode is now the preferred mode of connection for monitors.
* "osd_deep_scrub_large_omap_object_key_threshold" has been lowered to detect an
object with large number of omap keys more easily.
