+Upgrade

+
+autoinc
+    For all tables relying on autoinc feature, manually move element
+    at ``'hash_key' = 0`` to ``'hash_key' = -1``.
+
+transactions
+    Should be retro-compatible but you are strongly advised to adopt the
+    new API.
+    - specify ``targets`` and ``setters`` via ``Transactions._get_transactors``
+    - avoid any use of ``Transactions._get_target`` and ``Transactions._alter_target``
+    - save is now called automatically as long as at least 1 write was attempted
+    - ``__schema__`` might not be required anymore due to ``Transaction`` having a new one
+    - ``requester_id`` hash key must be set by the user
+    See these method's documentation for more informations
