Hi,

We have released ODB 1.5.0. The NEWS file entries for this release are
as follows:

  * Support for the PostgreSQL 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 13, "PostgreSQL Database" in the ODB manual.

  * New handling of the NULL semantics. Now, instead of being specified as
    part of the SQL type with the type pragma, there are separate null and
    not_null pragmas. The not_null pragma was used to control the NULL
    semantics of object pointers. Now the two pragmas are used consistently
    for object pointers and simple values (and, in the future, they will work
    for composite values and containers). To control the NULL semantics of
    the container's element values, the value_null and value_not_null pragmas
    have been added, similar to the value_type, value_column, etc., pragmas.
    For more information about the new mechanism, refer to Sections 10.2.3,
    10.2.8, 10.3.4, and 10.3.13 in the ODB manual.

    This is a backwards-incompatible change. Existing use cases that will
    require manual changes are listed below.

    For pragmas that apply to simple value types and data members of
    such types:

    #pragma db type("TEXT NOT NULL") => #pragma db type("TEXT")
    #pragma db type("TEXT NULL")     => #pragma db type("TEXT") null
    #pragma db type("TEXT")          => #pragma db type("TEXT") null

    For pragmas that apply to containers of pointers and data members of
    such types:

    #pragma db not_null              => #pragma db value_not_null

  * New pragma, default, allows the specification of the database default
    value. For more information, refer to Section 10.3.5, "default" in the
    ODB manual.

  * New pragmas, options, id_options, index_options, key_options, and
    value_options, allow the specification of additional column definition
    options. For more information, refer to Section 10.3.6, "options" in
    the ODB manual.

  * Support for database operations callbacks. Now a persistent class can
    register a callback function that will be called before and after every
    database operation (such as persist, load, update, or erase) is performed
    on an object of this class. A database operations callback can be used to
    implement object-specific pre and post initializations, registrations,
    and cleanups. For more information and an example, refer to Section
    10.1.4, "callback" in the ODB manual.

  * New option, --include-regex, allows the modification of the #include
    directive paths generated by the ODB compiler. This is primarily useful
    when placing the generated code into subdirectories and the #include
    directives have to be adjusted accordingly. The --include-regex-trace
    option is useful for debugging the expressions specified with
    --include-regex.

Source code and pre-compiled binary packages for this release are available
