+
+<p>This Calcite release makes it possible to exploit physical properties
+of relational expressions to produce more efficient plans, introducing
+collation and distribution as traits, <code>Exchange</code> relational operator,
+and several new forms of metadata.</p>
+
+<p>We add experimental support for streaming SQL.</p>
+
+<p>This release drops support for JDK 1.6; Calcite now requires 1.7 or
+later.</p>
+
+<p>We have introduced static <code>create</code> methods for many sub-classes of
+<code>RelNode</code>. We strongly suggest that you use these rather than
+calling constructors directly.</p>

+ Policy for case-sensitivity of identifiers should be configurable
+ * New connect-string parameter âlexâ, with allowable values
+ âORACLEâ, âMYSQLâ, âSQL_SERVERâ, âJAVAâ sets policy to be like those
+ databases, in terms of quote string, whether quoted and unquoted
+ identifiers are converted to upper/lower case, and whether
+ identifiers are matched case-sensitively. âJAVAâ is case-sensitive,
+ even for unquoted identifiers. It should be possible
+ for each connection to have its own settings for these. Objects
+ shared between sessions (views, materialized views) might
+ require more work.
+ * Added various internals to make it easy for developers to do the
+ right thing. When you need to look up a schema, table or
+ column/field name, you should use a catalog reader, and it will
+ apply the right case-sensitivity policy.

+ empty up the tree. (We already do this for union, filter, project.)
