 Revision history for DBIx::Class
 
+    * New Features / Changes
+        - A new zero-to-DBIC style manual: DBIx::Class::Manual::QuickStart
+
+    * Fixes
+        - More robust handling of circular relationship declarations by loading
+          foreign classes less frequently (should resolve issues like
+          http://lists.scsys.co.uk/pipermail/dbix-class/2013-June/011374.html)
+        - Fix multiple edge cases steming from interaction of a non-selecting
+          order_by specification and distinct and/or complex prefetch
+        - Clarify ambiguous behavior of distinct when used with ResultSetColumn
+          i.e. $rs->search({}, { distinct => 1 })->get_column (...)
+        - Setting quote_names propagates to SQL::Translator when producing
+          SQLite DDL (it is one of the few producers *NOT* quoting by default)
+        - Fix incorrect binding of large integers on old versions of
+          DBD::SQLite (now DBIC simply always binds SQLite ints as BIGINT)
+        - Silence (harmless) warnings on recent DBD::SQLite versions, when
+          inserting/updating large integers on 32bit ivsize systems (RT#76395)
+        - Back out self-cleaning from DBIx::Class::Carp for the time being
+          (as a side effect fixes RT#86267)
+        - Fix incorrect internal use of implicit list context in copy()
+        - Tests no longer fail if $ENV{DBI_DSN} is set
+        - Throw clearer exception on ->new_related() with a non-existent
+          relationship.
+        - Fix t/storage/replicated.t class loading problem
+        - Stop using the deprecated Class::MOP::load_class()
+
+    * Misc
+        - Replace $row with $result in all docs to be consistent and to
+          clarify various return values

+    * 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)
+          - Prefetch with limit on right-side ordered resultsets now works
+            correctly (via aggregated grouping)
+          - No longer order the insides of a complex prefetch subquery,
+            unless required to satisfy a limit
+          - Stop erroneously considering order_by criteria from a join under
+            distinct => 1 (the distinct should apply to the main source only)
+        - Massively optimize codepath around ->cursor(), over 10x speedup
+          on some iterating workloads.
+        - Support standalone \[ $sql, $value ] in literal SQL with bind
+          specifications: \[ '? + ?', 42, 69 ] is now equivalent to
+          \[ '? + ?', [ {} => 42 ], [ {} => 69 ] ]
+        - 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.
+        - Deprecate returning of prefetched 'filter' rels as part of
+          get_columns() and get_inflated_columns() data
+        - Invoking get_inflated_columns() no longer fires get_columns() but
+          instead retrieves data from individual non-inflatable columns via
+          get_column()
+        - Emit a warning on incorrect use of nullable columns within a
+          primary key
+        - Limited checks are performed on whether columns without declared
+          is_nullable => 1 metadata do in fact sometimes fetch NULLs from
+          the database (the check is currently very limited and is performed
+          only on resultset collapse when the alternative is rather worse)
+
     * 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
+        - Fix open cursors silently resetting when inherited across a fork
+          or a thread
+        - Properly support "MySQL-style" left-side group_by with prefetch
+        - Fix $grouped_rs->get_column($col)->func($func) producing incorrect
+          SQL (RT#81127)
         - Stop Sybase ASE storage from generating invalid SQL in subselects
           when a limit without offset is encountered
+        - Even more robust behavior of GenericSubQuery limit dialect
+        - Make sure deployment_statements() and cursor_class() are called on
+          a resolved storage subclass
+
+    * Misc
+        - Fix tests failing due to unspecified resultset retrieval order
+          (test suite now will pass with newest SQLite libs)
