If you're compiling you can use the pacific branch.
The latest pacific container would be based on the pacific branch, and
include the RC and additional fixes since then.
The RC packages are on https://download.ceph.com in the usual places, e.g.:
https://download.ceph.com/debian-16.1.0/
https://download.ceph.com/rpm-16.1.0/
Using these repos is described here:

There are just a couple remaining issues before the final release.
Please test it out and report any bugs.
I'm not sure where this RC can be found. I looked at https://github.com/ceph/
ceph/releases but the v16.1.0 tag shows up as from Jan. So I'm not sure if I
am looking in the correct place. I haven't tried this before so I may be
looking in the wrong place.
Context:
I wanted to retest a go-ceph test case that is currently failing on the
version of pacific available from ceph container (as of last week) [1].
If that doesn't work I wanted to try and apply a patch from a possibly related
issue. But since I haven't compiled ceph before I figured I start with the RC
first before trying out patches.

Thanks.
The full release notes are in progress here [0].
Notable Changes
---------------
* New ``bluestore_rocksdb_options_annex`` config
parameter. Complements ``bluestore_rocksdb_options`` and allows
setting rocksdb options without repeating the existing defaults.
* The cephfs addes two new CDentry tags, 'I' --> 'i' and 'L' --> 'l',
and on-RADOS metadata is no longer backwards compatible after
upgraded to Pacific or a later release.
* $pid expansion in config paths like ``admin_socket`` will now
properly expand to the daemon pid for commands like ``ceph-mds`` or
``ceph-osd``. Previously only ``ceph-fuse``/``rbd-nbd`` expanded
``$pid`` with the actual daemon pid.
* The allowable options for some ``radosgw-admin`` commands have been
changed.
* ``mdlog-list``, ``datalog-list``, ``sync-error-list`` no longer
accepts start and end dates, but does accept a single optional
start marker. * ``mdlog-trim``, ``datalog-trim``,
``sync-error-trim`` only accept a single marker giving the end of
the trimmed range. * Similarly the date ranges and marker ranges
have been removed on the RESTful DATALog and MDLog list and trim
operations.
* ceph-volume: The ``lvm batch`` subcommand received a major
rewrite. This closed a number of bugs and improves usability in
terms of size specification and calculation, as well as idempotency
behaviour and disk replacement process. Please refer to
https://docs.ceph.com/en/latest/ceph-volume/lvm/batch/ for more
detailed information.
* Configuration variables for permitted scrub times have changed. The
legal values for ``osd_scrub_begin_hour`` and ``osd_scrub_end_hour``
are 0 - 23. The use of 24 is now illegal. Specifying ``0`` for
both values causes every hour to be allowed. The legal vaues for
``osd_scrub_begin_week_day`` and ``osd_scrub_end_week_day`` are 0 -
6. The use of 7 is now illegal. Specifying ``0`` for both values
causes every day of the week to be allowed.
* Multiple file systems in a single Ceph cluster is now stable. New
Ceph clusters enable support for multiple file systems by
default. Existing clusters must still set the "enable_multiple" flag
on the fs. Please see the CephFS documentation for more information.
* volume/nfs: Recently "ganesha-" prefix from cluster id and
nfs-ganesha common config object was removed, to ensure consistent
namespace across different orchestrator backends. Please delete any
existing nfs-ganesha clusters prior to upgrading and redeploy new
clusters after upgrading to Pacific.
* A new health check, DAEMON_OLD_VERSION, will warn if different
versions of Ceph are running on daemons. It will generate a health
error if multiple versions are detected. This condition must exist
for over mon_warn_older_version_delay (set to 1 week by default) in
order for the health condition to be triggered. This allows most
upgrades to proceed without falsely seeing the warning. If upgrade
is paused for an extended time period, health mute can be used like
this "ceph health mute DAEMON_OLD_VERSION --sticky". In this case
after upgrade has finished use "ceph health unmute
DAEMON_OLD_VERSION".
* MGR: progress module can now be turned on/off, using the commands:
``ceph progress on`` and ``ceph progress off``. * An AWS-compliant
API: "GetTopicAttributes" was added to replace the existing
"GetTopic" API. The new API should be used to fetch information
about topics used for bucket notifications.
* librbd: The shared, read-only parent cache's config option
``immutable_object_cache_watermark`` now has been updated to
property reflect the upper cache utilization before space is
reclaimed. The default ``immutable_object_cache_watermark`` now is
``0.9``. If the capacity reaches 90% the daemon will delete cold
cache.
* OSD: the option ``osd_fast_shutdown_notify_mon`` has been introduced
to allow the OSD to notify the monitor it is shutting down even if
``osd_fast_shutdown`` is enabled. This helps with the monitor logs
on larger clusters, that may get many 'osd.X reported immediately
failed by osd.Y' messages, and confuse tools.
