+* Version 1.2
+
+ Carbonado 1.2 adds many new features, which are summarized here and in the {{{http://carbonado.svn.sourceforge.net/viewvc/*checkout*/carbonado/trunk/Carbonado/RELEASE-NOTES.txt}release notes}}:
+
+ * General features
+
+ * Loads and queries can invoke {{{apidocs/com/amazon/carbonado/Trigger.html#afterLoad%28S%29}triggers}}.
+
+ * Added support for {{{apidocs/com/amazon/carbonado/Derived.html}derived}} properties.
+
+ * Storable property values can be accessed by {{{apidocs/com/amazon/carbonado/Storable.html#getPropertyValue%28java.lang.String%29}name}} in addition to the direct method.
+
+ * Repositories
+
+ * New {{{apidocs/com/amazon/carbonado/repo/map/MapRepositoryBuilder.html}volatile repository}} provided, backed by a {{{http://java.sun.com/javase/6/docs/api/java/util/concurrent/ConcurrentSkipListMap.html}ConcurrentSkipListMap}}.

+ * Replicated repository resync operation allows a {{{apidocs/com/amazon/carbonado/capability/ResyncCapability.html#resync%28java.lang.Class,%20com.amazon.carbonado.capability.ResyncCapability.Listener,%20double,%20java.lang.String,%20java.lang.Object...%29}listener}} to be installed which can monitor progress or make changes.
+
+ * Berkeley DB repositories add support for BigInteger and BigDecimal property types.
+
+ * JDBC features
+
+ * Created {{{apidocs/com/amazon/carbonado/Automatic.html}@Automatic}} annotation, which enables MySQL auto-increment columns.
+
+ * Added {{{apidocs/com/amazon/carbonado/sequence/StoredSequence.html}sequence support}} for SQL databases that don't natively support sequences.
+
+ * Support for {{{apidocs/com/amazon/carbonado/repo/jdbc/JDBCRepositoryBuilder.html#setAutoVersioningEnabled%28boolean,%20java.lang.String%29}automatic version management}}, eliminating the requirement that triggers be installed on the database.
+
+ * More lenient with respect to column mappings: numbers and dates can represented by Strings; character data type supported; non-null column can be marked as @Nullable if also @Independent.
+
+ * Query engine features
+
+ * Added {{{apidocs/com/amazon/carbonado/Query.html#fetchSlice%28long,%20java.lang.Long%29}Query.fetchSlice}} method for supporting limits and offsets.
+
+ * Derived properties can be indexed, allowing function and join indexes to be defined.
+
+ * Added support for "where exists" and outer joins in queries via new syntax.
+
+ * Added convenience method, {{{apidocs/com/amazon/carbonado/Query.html#exists%28%29}Query.exists}}.
+
+ * Optimizations for covering indexes when using Berkeley DB.
