This chapter covers both major changes to existing functionality, and also deprecated and removed functionality. No incompatible changes have been made since OpenDJ ${stableServerVersion}. This chapter reflects changes made in version ${stableServerVersion}.

OpenDJ improves on earlier releases introducing many new features. Also take the following into account. The upgrade process and upgrade command have changed to facilitate native packaging on more platforms. See Upgrading to OpenDJ ${stableServerVersion} for instructions. The default DB cache size is now 50%, rather than 10%. If you have multiple backends, configure cache sizes accordingly. The number of LDAP request handlers now defaults to half the CPU count. The replication purge delay default has increased from one day to three days. Syntax checking has been added for certificate and country attribute values. This affects applications updating those attribute values. Applications updating country attribute values must now use Country String syntax for example, which uses two-character codes from ISO 3166 such as US instead of full names such as United States. The following global ACI settings have changed. OpenDJ directory server now allows any client to use the LDAP Permissive Modify Request control, 1.2.840.113556.1.4.1413, by default for newly installed servers. The "Anonymous read access" global ACI has changed. The list of attributes that are not allowed has been changed to add includedAttributes and to remove targetUniqueID. When you upgrade from earlier versions of OpenDJ, however, the previous global-aci settings are not updated. To apply the changes manually, change the relevant global-aci settings by using the dsconfig command. An example of how to change a global-aci property can be found in the Administration Guide, ACI: Disable Anonymous Access. For the SNMP Connection Handler, the default security-agent-file has changed to opendj-snmp.security (OPENDJ-982), and the upgrade process changes the file name. The community has also changed to OpenDJ. If the SNMP Connection Handler fails to start after upgrade, use the dsconfig command to make sure that the security-agent-file property is correctly set for your installation.

Support for Java 6 is deprecated and likely to be removed in a future release. OpenDJ ${stableServerVersion} makes use of new environment variables aligned with the project name to use OPENDJ. Use of the old variables is Deprecated. The old variables are likely to be removed in a future release. The dsframework command is Deprecated and likely to be removed in a future release. The next major version of OpenDJ LDAP SDK includes improvements and changes that are not compatible with the 2.x SDK.

Native packages in SVR4 format for Solaris are not provided at this time.
