 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

+    * 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
+          attributes.
+        - 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,
+          unless required to satisfy a limit
+
+    * 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
+          SQL (RT#81127)

+    * New Features / Changes
+        - Revert to passing the original (pre-0.08240) arguments to
+          inflate_result() and remove the warning about ResultClass
+          inheritance.
+        - Optimize the generated rowparsers even more - no user-visible
+          changes.
+        - Emit a warning on incorrect use of nullable columns within a
+          primary key

+0.08240-TRIAL (EXPERIMENTAL BETA RELEASE) 2013-02-14 05:56 (UTC)
+    * New Features / Changes
+        - Rewrite from scratch the result constructor codepath - many bugfixes
+          and performance improvements (the current codebase is now capable of
+          outperforming both DBIx::DataModel and Rose::DB::Object on some
+          workloads). Some notable benefits:
+          - Multiple has_many prefetch
+          - Partial prefetch - you now can select only columns you are
+            interested in, while preserving the collapse functionality
+            (collapse is now exposed as a first-class API attribute)
+          - Prefetch of resultsets with arbitrary order
+            (RT#54949, RT#74024, RT#74584)
+          - Prefetch no longer inserts right-side table order_by clauses
+            (massively helps the deficient MySQL optimizer)
+        - Massively optimize codepath around ->cursor(), over 10x speedup
+          on some iterating workloads.
+
+    * Fixes
+        - Fix open cursors silently resetting when inherited across a fork
+          or a thread
+        - Fix duplicated selected columns when calling 'count' when a same
+          aggregate function is used more than once in a 'having' clause
+          (RT#83305)
+
+    * Misc
+        - Fixup our distbuilding process to stop creating world-writable
+          tarball contents (implicitly fixes RT#83084)
+        - Added strict and warnings tests for all lib and test files
