Version 1.2.0

  * New profile, boost, provides persistence support for the Boost libraries.
    This version covers the most commonly used types from the smart_ptr,
    unordered, and date_time libraries. The boost profile implementation is
    provided by the libodb-boost library. For more information refer to
    Chapter 11, "Profiles Introduction" and Chapter 12, "Boost Profile" in
    the ODB manual as well as the 'boost' example in the odb-examples package.

  * Support for embedded database schemas. The new option, --schema-format,
    allows the selection of the schema format. The valid values for this
    option are 'sql' for a standalone SQL file and 'embedded' for a schema
    embedded into the generated C++ code. The new odb::schema_catalog class
    provides support for accessing embedded schemas from within the
    application. For details refer to Section 3.3, "Database" in the ODB
    manual as well as the 'schema/embedded' example in the odb-examples
    package.

  * New exceptions: odb::recoverable, odb::connection_lost, and odb::timeout.
    The odb::recoverable exception is a common base class for all recoverable
    ODB exceptions. The other two exceptions plus odb::deadlock now inherit
    from this base. Refer to Section 3.5, "Error Handling and Recovery" for
    details.

  * Support for connection validation (ping) in MySQL connection_pool_factory.
    This transparently deals with the MySQL server closing connections after
    a certain period of inactivity.

  * New namespace, odb::core, contains using-declarations for the core ODB
    constructs, such as the database, transaction, etc. The primary use of
    this namespace is in the using-directives:

    using namespace odb::core;

    The above form should be preferred over the old variant:

    using namespace odb;

    The new approach brings all the essential ODB names into the current
    namespace without any of the auxiliary objects such as traits, etc., which
    minimizes the likelihood of conflicts with other libraries.  Note that you
    should still use the odb namespace when qualifying individual names, for
    example, odb::database.

  * New option aliases: -q for --generate-query and -s for --generate-schema.

  * Support for the default options file. Now, if configured, the ODB compiler
    loads the default options file (by default ../etc/odb/default.options,
    relative to the ODB compiler binary). This file can be used for
    installation-wide customization, such as adding extra include search
    paths.

Version 1.1.0

  * Support for storing containers in the database. For more information refer
    to Chapter 5, "Containers" in the ODB manual as well as the 'container'
    example in the odb-examples package.

  * Support for unidirectional and bidirectional object relationships,
    including lazy loading. For more information refer to Chapter 6,
    "Relationships" in the ODB manual as well as the 'relationship' and
    'inverse' examples in the odb-examples package.

  * Support for composite value types. For more information refer to Chapter
    7, "Composite Value Types" in the ODB manual as well as the 'composite'
    example in the odb-examples package.

  * Support for sessions. A session is an application's unit of work that
    may encompass several database transactions. In this version of ODB a
    session is just an object cache. For more information refer to Chapter
    8, "Session" in the ODB manual.

  * Support for custom object pointers that allows you to use smart pointers
    to return, pass, and cache persistent objects. See Section 3.2, "Object
    Pointers" in the ODB manual for details.

  * Support for native SQL statement execution. See Section 3.9, "Executing
    Native SQL Statements" in the ODB manual for details.

  * New option, --profile/-p, instructs the ODB compiler to use the specified
    profile library. See the ODB compiler command line manual for details.

  * Support for literal names (template-id, derived type declarator such as
    pointers, etc) in data member declarations. Now, for example, you can use
    std::vector<std::string> directly instead of having to create a typedef
    alias for it.

  * Support for inheritance from transient base types for object types and
    composite value types.

  * New example, 'schema/custom', shows how to map persistent C++ classes to
    a custom database schema.

  * New options, --odb-prologue, --odb-epilogue, allow inclusion of extra code
    into the ODB compilation process. This can be useful for making additional
    traits specializations or ODB pragmas known to the ODB compiler.

  * Support for persistent classes without default constructors. For objects
    of such classes only the load() and find() database functions that
    populate an existing instance can be used. Similarly, only the load()
    query result iterator function which populates an existing instance can
    be used.

Version 1.0.0

  * Initial release.
