The changes and bug fixes introduced by MongoDB include the following:
libsasl2dependencies are added for DEB-based operating systems to enable GSSAPI and Kerberos authentication to work out-of-the box after installing MongoDB (SERVER-54729)
The number of modify updates in WiredTiger is now limited to prevent performance issues (WT-7776)
Errors related to proxy connections receive new error codes so that they don’t change the behavior of clients’ drivers (SERVER-50549)
Pre-warming of connection pools in mongos tier (SERVER-44152)
Improvements to Secondary slowdowns or hangs (SERVER-34938)
PSMDB-918: Disable the ability to delete the
mongoduser in RPM packages during the re-installation of Percona Server for MongoDB. - This preserves the permissions to the MongoDB data directory for the
mongoduser since its user ID and group ID remain unchanged.
PSMDB-873: RPM packages now include the
cyrus-saslmodules to enable LDAP authentication via native LDAP against Active Directory
