    * New Features
        - When using non-scalars (e.g. arrays) as literal bind values it is no
          longer necessary to explicitly specify a bindtype (this turned out
          to be a mostly useless overprotection)

    * Fixes
        - Ensure leaving an exception stack via Return::MultiLevel or something
          similar produces a large warning
        - Another relatively invasive set of ::FilterColumn changes, covering
          potential data loss (RT#111567). Please run your regression tests!
        - Ensure failing on_connect* / on_disconnect* are dealt with properly,
          notably on_connect* failures now properly abort the entire connect
        - Fix use of ::Schema::Versioned combined with a user-supplied
          $dbh->{HandleError} (GH#101)
        - Fix parsing of DSNs containing driver arguments (GH#99)
        - Fix silencing of exceptions thrown by custom inflate_result() methods
        - Fix complex prefetch when ordering over foreign boolean columns
          ( Pg can't MAX(boolcol) despite being able to ORDER BY boolcol )
        - Fix infinite loop on ->svp_release("nonexistent_savepoint") (GH#97)
        - Fix spurious ROLLBACK statements when a TxnScopeGuard fails a commit
          of a transaction with deferred FK checks: a guard is now inactivated
          immediately before the commit is attempted (RT#107159)
        - Fix the Sybase ASE storage incorrectly attempting to retrieve an
          autoinc value when inserting rows containing blobs (GH#82)
        - Remove spurious exception warping in ::Replicated::execute_reliably
          (RT#113339)
        - Work around unreliable $sth->finish() on INSERT ... RETURNING within
          DBD::Firebird on some compiler/driver combinations (RT#110979)
        - Fix leaktest failures with upcoming version of Sub::Quote
        - Really fix savepoint rollbacks on older DBD::SQLite (fix in 0.082800
          was not sufficient to cover up RT#67843)

    * Misc
        - Test suite is now officially certified to work under very high random
          parallelism: META x_parallel_test_certified set to true accordingly
        - Typo fixes from downstream debian packagers (RT#112007)
