+**Features**
+
+
+* 1st version it's always "setup"
+
+  In all projects' usecases the 1st version is always to setup the initial state.
+  Adopting `setup` as the 1st version makes also easier to squash intermediate version
+  all in one as the project and its releases grow up.
+
+* Support 5 digits version
+
+  Now you can use 5 digits versions as per odoo modules.
+  For instance: `11.0.3.0.1`. This give us better numbering for patches
+  and makes versionig withing Odoo world more consistent.
+  Old 3 digits versions are still supported for backward compat.
+
+Full rationale for above changes available here

+
+* Backup option
+
+  Migration allows using a `backup` command in order to perform specific
+  commands (unless explicitly opted-out) before the migration step.
+
+  No backup machinery provided as you are suppose to run your own command
+  to execute the backup.
