 Release Notes
 -------------
+1.8 - 2011-12-08
+
+  * Adds configuration attribute for item property-case (preserve, lower, upper
+    and legacy). Starting with new schema version 7, the default is preserve. Older
+    schema versions continue to have the legacy behavior of lowercasing
+    property names from column names but not from pivoted values.
+
+    preserve - Use whatever case we get back from the database
+    lower    - All property names are converted to locale lower case
+    upper    - All property names are converted to locale upper case
+    legacy   - Property names from sql column labels are converted to lower case,
+               but property names from vertical table values are preserved.
+
+  * Fixes "If a subquery is empty, it should be ignored (and reported) and not
+    throw an error."
+
+  * Adds support for unscopedJsonColumns to be able to merge in JSON column
+    data to the top level properties. Deprecates property "jsonColumnNames" in
+    favor of more explicit "scopedJsonColumns" for the same behavior. Adds new
+    property "unscopedJsonColumns" for columns that should be merged into the
+    top-level item properties.
+
+  * Makes subqueries use NullDefaultCaseInsensitiveParameterSource. If subquery
+    uses a bound parameter that is not present in the main item properties, then
+    null is used for the parameter value.
 
 1.7 - 2011-11-04
-  * Adds support for add-to-item for deltas and snapshots (the Discovery Engine does not support add-to-item for bulk or full
-    changesets). The add-to-item configuration element supports the same attributes and child configuration elements as set-item.

   * Adds another subquery test scenario.
-  * Fixes Data Tool Outputs Empty Strings: If a column returns an empty string, the data tool still outputs the column value.
-    Empty strings should not be output.
+  * Fixes Data Tool Outputs Empty Strings: If a column returns an empty string,

+    output.
   * Fixes merge-columns should not be case sensitive.
 
 1.6 - 2011-09-28
 
-  * Adds support for provider and kind to Discovery Data Tool. The configuration elements can now take optional attributes
-    providerColumn and kindColumn. If either of these are specified, then the resulting changeset set-item and remove-item
-    elements will not have an id attribute, and instead will have locator, provider and kind attributes.
-    The providerColumn and kindColumn are not included in the resulting set-item properties, since that would be redundant.
-  * No longer includes id column in set-item properties, since it is redundant to the set-item id attribute.
