 Revision history for DBIx::Class
 
+    * Fixes
+        - Fix _dbi_attrs_for_bind() being called befor DBI has been loaded
+          (regression in 0.08210)
+        - Fix update/delete operations on resultsets *joining* the updated
+          table failing on MySQL. Resolves oversights in the fixes for
+          RT#81378 and RT#81897
+        - Stop Sybase ASE storage from generating invalid SQL in subselects
+          when a limit without offset is encountered

     * New Features / Changes
+        - Officially deprecate the 'cols' and 'include_columns' resultset
+          attributes
+        - Remove ::Storage::DBI::sth() deprecated in 0.08191
+
+    * Fixes
+        - Work around a *critical* bug with potential for data loss in
+          DBD::SQLite - RT#79576
+        - Audit and correct potential bugs associated with braindead reuse
+          of $1 on unsuccessful matches
+        - Fix incorrect warning/exception originator reported by carp*() and
+          throw_exception()

+    * New Features / Changes
+        - Prefetch with limit on right-side ordered resultsets now works
+          correctly (via aggregated grouping)
         - Changing the result_class of a ResultSet in progress is now
           explicitly forbidden. The behavior was undefined before, and
           would result in wildly differing outcomes depending on $rs

         - Scale back validation of the 'as' attribute - in the field
           there are legitimate-ish uses of a inflating into an apparently
           invalid relationship graph
+        - Warn in case of iterative collapse being upgraded to an eager
+          cursor slurp
+        - No longer order the insides of a complex prefetch subquery,

+    * Fixes
+        - Properly consider unselected order_by criteria during complex
+          subqueried prefetch
+        - Properly support "MySQL-style" left-side group_by with prefetch
+        - Fix $grouped_rs->get_column($col)->func($func) producing incorrect
