I would like to release 1.16.1 tomorrow. There is one open ticket still in the 
milestone, but there is just a minor question in the PR 
(https://github.com/SSSD/sssd/pull/528) and even if we can’t merge that PR by 
tomorrow, I think the ticket should not be blocking the release. Is everyone OK 
with that?

Below please see a draft of the release notes. Comments are welcome.

SSSD 1.16.1


New Features
  * A new option ``auto_private_groups`` was added.  If this option is
    enabled, SSSD will automatically create user private groups based on
    user's UID number. The GID number is ignored in this case. Please
    see https://docs.pagure.org/SSSD.sssd/design_pages/auto_private_groups.html
    for more details on the feature.

  * The SSSD smart card integration now supports a special type of PAM
    conversation implemented by GDM which allows the user to select the
    appropriate smrt card certificate in GDM. Please refer to
    for more details about this feature.

  * A new API for accessing user and group information was added. This API
    is similar to the tradiional Name Service Switch API, but allows
    the consumer to talk to SSSD directly as well as to fine-tune
    the query with e.g. how cache should be evaluated. Please see
    for more information on the new API.

  * The ``sssctl`` command line tool gained a new command ``access-report``,
    which can generate who can access the client machine. Currently only 
    the report on an IPA client based on HBAC rules is supported. Please see
    for more information about this new feature.

  * The ``hostid`` provider was moved from the IPA specific code to the generic
    LDAP code. This allows SSH host keys to be access by the generic LDAP 
    as well. See the ``ldap_host_*`` options in the ``sssd-ldap`` manual page
    for more details.

  * Setting the ``memcache_timeout`` option to 0 disabled creating the
    memory cache files altogether. This can be useful in cases there is a
    bug in the memory cache that needs working around.

Performance enhancements
  * Several internal changes to how objects are stored in the cache improve
    SSSD performance in environments with large number of objects of the same
    type (e.g. many users, many groups). In particular, several useless indexes
    were removed and the most common object types no longer use the indexed
    ``objectClass`` attribute, but use unindexed ``objectCategory`` instead

  * In setups with ``id_provider=ad`` that use POSIX attributes which
    are replicated to the Global Catalog, SSSD uses the Global Catalog to
    determine which domain should be contacted for a by-ID lookup instead
    of iterating over all domains.  More details about this feature can
    be found at

Notable bug fixes
 * A crash in ``sssd_nss`` that might have happened if a list of domains
   was refreshed while a NSS lookup using this request was fixed (#3551)

 * A potential crash in ``sssd_nss``  during netgroup lookup in case the
   netgroup object kept in memory was already freed (#3523)

 * Fixed a potential crash of ``sssd_be`` with two concurrent sudo refreshes
   in case one of them failed (#3562)

 * A memory growth issue in ``sssd_nss`` that occured when an entry was
   removed from the memory cache was fixed (#3588)

 * Two potential memory growth issues in the ``sssd_be`` process that could
   have hit configurations with ``id_provider=ad`` were fixed (#3639)

 * The ``selinux_child`` process no longer crashes on a system where SSSD
   is compiled with SELinux support, but at the same time, the SELinux policy
   is not even installed on the machine (#3618)

 * The memory cache consistency detection logic was fixed. This would prevent
   printing false positive memory cache corruption messages (#3571)

 * SSSD now remembers the last successfuly discovered AD site and use this
   for DNS search to lookup a site and forest during the next lookup. This
   prevents time outs in case SSSD was discovering the site using the global
   list of DCs where some of the global DCs might be unreachable. (#3265)

 * SSSD no longer starts the implicit file domain when configured with
   ``id_provider=proxy`` and ``proxy_lib_name=files``. This bug prevented
   SSSD from being used in setups that combine identities from UNIX files
   together with authentication against a remote source unless a files
   domain was explicitly configured (#3590)

 * The IPA provider can handle switching between different ID views better

 * Previously, the IPA provider kept SSH public keys and certificates from
   an ID view in its cache and returned them even if the public key or
   certificate was then removed from the override (#3602, #3603)

 * FleetCommander profiles coming from IPA are applied even if they are
   assigned globally (to ``category: ALL``), previously, only profiles
   assigned to a host or a hostgroup were applied (#3449)

 * It is now possible to reset an expired password for users with 2FA
   authentication enabled (#3585)

 * A bug in the AD provider which could have resulted in built-in AD groups
   being incorrectly cached was fixed (#3610)

 * The SSSD watchdog can now cope better with time drifts (#3285)

 * The ``nss_sss`` NSS module's return codes for invalid cases were fixed

 * A bug in the LDAP provider that prevented setups with id_provider=proxy
   and auth_provider=ldap with LDAP servers that do not allow anonymous
   binds from working was fixed (#3451)

Packaging Changes
 * The FleetCommander desktop profile path now uses stricter permissions,
   751 instead of 755 (#3621)

 * A new option ``--logger`` was added to the ``sssd(8)`` binary. This option
   obsoletes old options such as ``--debug-to-files``, although the old options
   are kept for backwards compatibility.

Documentation Changes
There are no notable documentation changes such as options changing default
values etc in this release.
