[odb-announcements] ODB 1.7.0 released

[Boris Kolpackov]

Hi,

We have released ODB 1.7.0. The NEWS file entries for this release are
as follows:

  * Support for the Oracle database. The provided connection factories
    include 'new' (a new connection is created every time one is requested)
    and 'pool' (a pool of connections is maintained). The Boost and Qt
    profiles have been updated to support this database. For more information,
    refer to Chapter 16, "Oracle Database" in the ODB manual.

    Note also that the Oracle runtime (libodb-oracle) is licensed under a
    different license compared to other database runtimes. For more
    information, refer to the ODB License page:

    http://www.codesynthesis.com/products/odb/license.xhtml

  * Support for optimistic concurrency. For more information refer to Chapter
    11, "Optimistic Concurrency" in the ODB manual as well as the 'optimistic'
    example in the odb-examples package.

  * Support for read-only objects, composite value types, and data members.
    The new readonly pragma can be used to declare one of these entities as
    read-only. Constant data members are automatically treated as read-only.
    For more information, refer to Section 12.1.4 "readonly (object)",
    Section 12.3.6 "readonly (composite value)", and Section 12.4.10
    "readonly (data member)" in the ODB manual.

  * Support for persistent classes without object identifiers. Such classes
    have to be explicitly declared as not having an object id and they have
    limited functionality. For more information, refer to Section 12.1.5
    "id" in the ODB manual.

  * Support for SQL statement execution tracing. For more information, refer
    to Section 3.12 "Tracing SQL Statement Execution" in the ODB manual.

  * Support for mapping char[N], unsigned char[N], and std::vector<unsigned
    char> to the BLOB (or equivalent) types. For more information, refer to
    Chapters 13 (for MySQL), 14 (for SQLite), 15 (for PostgreSQL), and 16
    (for Oracle) in the ODB manual.

  * Query result iterator now provides the id() function which allows one
    to get the object id without loading the object. For more information,
    refer to Section 4.4 "Query Result" in the ODB manual.

  * Support for microsecond precision in Boost and Qt date-time types
    mapping to PostgreSQL date-time data types. Additionally, Qt QDateTime
    values stored in a PostgreSQL database can now be earlier than the UNIX
    epoch.

We would like to thank everyone who reported bugs, shared test results, or
helped test one of the pre-releases.
