+Cayenne Upgrade Information 1.2 RC1 (release candidate)
+Date: 05/31/2006
+============================================
+
+
+GENERAL UPGRADE NOTES:
+
+* WARNING: API deprecated in 1.1 is removed from 1.2.
+
+* For the complete list of new features since the last stable release see
+ User Guide page at [cayenne_install_dir]/doc/userguide/introduction/whats-new.html
+
+* Expect CayenneModeler to be backwards compatible and be able to read
+ older project files. However once you save old projects with new Modeler,
+ the latest format will be used, possibly making saved project incompatible
+ with older versions of the Modeler and runtime.
+
+* Clean Recompile: Cayenne 1.2 introduces a few API changes. Most of them are done
+ to the backend and should not affect the applications written with the earlier versions.
+ However it is a good idea to perform a clean compilation of all Java code that relies on
+ Cayenne. Updating calls to deprecated methods is also a very good idea.
+
+* Pay attention to CayenneModeler validation warnings.
+
+
+UPGRADE FROM 1.1:
+
+* Cayenne tools and runtime now REQUIRE at least JDK 1.4 (or higher). They won't work on JDK 1.3.
+ If you are still on 1.3, upgrade your JDK if you can. If you can not, consider staying on
+ Cayenne 1.1.
+
+* 1.2 no longer needs Jakarta BeanUtils.
+
+* 1.2 no longer relies on ClassLoader provided by Configuration (this API is deprecated as
+ a matter of fact). Current code uses Thread.currentThread().getContextClassLoader().
+
+* In 1.2 PostgreSQLAdapter uses DB sequences for primary key generation instead of
+ AUTO_PK_TABLE. To port an existing application, you will need to create those
+ sequences (e.g. using the Modeler) and assign correct current values to them
+ (e.g. taken from the old AUTO_PK_TABLE). After that AUTO_PK_TABLE can be dropped.
+
+* In 1.2 PostgreSQLAdapter's default "BLOB" mapping is changed from "bytea" to "oid". It
+ is still possible to use bytea, but watch for the Modeler-generated schema scripts -
+ they will contain "oid". The easiest way to migrate your mapping (if you don't want to
+ change the DB) is to remap all bytea columns as LONGVARBINARY DbAttributes instead of BLOB.
+
+* For extra portability encoding of entity type in the ObjectId is now based on ObjEntity name,
+ not Java class as before. If you had ObjEntities with matching names but different class names
+ in different DataMaps, you will need to ensure entity name uniqueness. See CAY-521 for details.
+
+* ObjectId methods "getObjClass" and "getObjectClass" are removed (it wasn't possible to deprecate
+ them and still preserve meaningful functionality). Constructors that take Class as the first argument
+ are deprecated and will only work if entity naming follows CayenneModeler default conventions of
+ using unqualified class name as the entity name.
+
+* TempObjectId is deprecated and is no longer used by Cayenne internally. If you were
+ referencing TempObjectId explicitly in your code (e.g. if(id instanceof TempObjectId) ... ),
+ you will need to modify the code and use "isTemporary()" superclass method.
+
+* The meaning of SnapshotEvent "source" and "postedBy" attributes is reversed per CAY-395 for
+ better efficiency. If you implemented custom listeners of SnapshotEvents, you may need to
+ doublecheck their logic. From now on events use DataRowStore as source, and EventBridge or
+ ObjectStore as postedBy, depending on whether this was a local or a remote event. I.e. the
+ new structure is the opposite to what we used in 1.1.
+
+* Cayenne stack events are no longer sent via a shared "default" EventManager.
+ If you were using EventManager.getDefaultManager() to communicate or receive Cayenne stack
+ events, you'll have to switch to Configuration.getEventManager(). Otherwise default manager
+ can be accessed as before.
+
+* Query.setLoggingLevel/getLoggingLevel methods are removed from the interface and AbstractQuery
+ implementor. As multi-tier Cayenne doesn't use Log4J, it was no longer possible to keep these methods
+ deprecated.
+
+* Thread-bound Transactions:
+ QueryEngine.performQueries(Collection,OperationObserver resultConsumer,Transaction) is deprecated and
+ no longer used internally to further decouple layers in the access stack. This DOES NOT AFFECT most
+ users. Only if you (a) implemented custom transactions and (b) manually manage their commit/rollback,
+ you will also have to bind and unbind such Transactions to the current thread manually, for Cayenne stack
+ classes to pick them up.
+
+* To force refresh of cached query results, one of the two new cache policies should be used
+ instead of "setRefreshingObjects(..)" ("setRefreshingObjects" should only be used for its
+ original purpose - refreshing individual objects, not list contents).
+
+ http://objectstyle.org/confluence/display/CAYDOC/Caching+Query+Results
+
+* ObjectStore no longer stores database snapshots of object. As a result a method "retainSnapshot(DataObject object)"
+ is removed, as its meaningful deprecation is not possible.
