New APIs for this features are described in Chapter 12, "OCCI Application Programming Interface", section on Statement Class:
This feature also introduces a new BatchSQLException Class, which extends the SQLException Class. It is described in Chapter 12, "OCCI Application Programming Interface", and has the following methods in addition to the ones it naturally inherits:
This release added support for determining the version of the client library used at run time and at compile time, and for determining the version of the Oracle server. The description and usage notes for this feature are documented in Chapter 2, " Installation and Upgrading", section "Determining Client and Server Versions".

Array Pinning for Objects: Section "Transient Objects" in Chapter 4, " Object Programming".
Section in "Migrating C++ Applications Using OCCI" in Chapter 4, " Object Programming"
Timestamp Class in Chapter 12, "OCCI Application Programming Interface"behavior is enhanced:
Users no longer need to convert to GMT when using Timestamp() constructor, or in methods setDate() and setTime()
New constructors that support timezone information as string or UString(Unicode) enable users to pass a region name, such as "US/Eastern", as a timezone. These provide daylight savings(DST) support. Using an empty string, "", constructs a timestamp in the local timezone.
