We have just released the 3.2.0 version of the UnboundID LDAP SDK for Java. It is available for download via the LDAP.com website or from GitHub, as well as the Maven Central Repository.

You can get a full list of changes included in this release from the release notes (or the Commercial Edition release notes for changes specific to the Commercial Edition). Some of the most significant changes include:

• Added a new transform-ldif tool that can be used to apply a number of transformations to data in an LDIF file. This includes the ability to scramble, replace, redact, or exclude a specified set of attributes; to replace existing values for a specified attribute; to use a sequential counter for values of a specified attribute; to add a given set of values to entries matching specified criteria; to exclude entries matching specified criteria; to rename attributes; to replace the base DN for entries in a specified subtree; and to flatten a DIT.
• Updated all classes that offer a public void close() method that doesn’t throw any exceptions other than a possible IOException so that they implement the java.io.Closeable interface. This includes classes like LDAPConnection, LDAPConnectionPool, LDIFReader, LDIFWriter, and all EntrySource implementations. This allows code using these classes to take advantage of the try-with-resources facility introduced in Java SE 7.
• Added support for parsing entries that contain information about the operations processed in the server for servers that support the syntax described in draft-chu-ldap-logschema-00.
• Updated the modrate tool to make a number of improvements, including support for a number of controls, the ability to replace multiple values rather than just a single value, or the ability to perform an increment modification rather than a replace modification.
• Added a new JSONBuffer class that can be used to efficiently construct the string representation of a JSON object, and a JSONObjectReader class that can be used to read JSON objects from an input stream. Added the ability to generate formatted, multi-line string representations of JSON objects with improved human readability.
• Updated the LDIF reader to make it possible to specify the character set to use when reading data. Updated the LDIF writer to make it possible to automatically include a comment below any base64-encoded values that provides a non-base64-encoded representation (with special characters escaped) of the preceding value.
• Updated the in-memory directory server to support the LDAP no-operation control as described in draft-zeilenga-ldap-noop-12.
• Added a new base64 command-line tool that can be used to encode and decode data using the base64 format.
• Dramatically improved the robustness of the identify-references-to-missing-entries and identify-unique-attribute-conflicts tools.
• Updated the argument parser to add support for subcommands with their own distinct set of arguments.
• Added support for timestamp arguments, which can be used to specify timestamps in either the generalized time syntax (including the time zone), or in a number of formats that indicate a time in the local time zone.
• Updated the command-line tool API to provide the ability to default to interactively prompt for passwords that may be needed but not provided, and to send output to a specified file.
• Updated the rate adjustor so that generated sample rate files include a number of additional examples for common patterns like square, stairstep, sine, sawtooth, triangle, and hockey stick.
