Version 1.3.0 * Support for the SQLite database, including shared cache and unlock notification to aid concurrency. For more information, refer to Chapter 11, "SQLite Database" in the ODB manual. 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 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.
