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.
