   trait type

+  - Added `side()` and `unpaired_side()` methods to `ImbalanceMsg` that convert the fields
+    of the same name to the `Side` enum
+  - Added `pretty_auction_time` property in Python for `ImbalanceMsg`
+  - Added `Default` implementation for `StatUpdateAction`

+    DBN versions
+  - Added more floating-point price getters to `ImbalanceMsg`
+  - Added floating-point price getter to `StatMsg` and `v1::StatMsg`
+
+### Breaking changes

+  - Changed `SystemMsg::code()` and `ErrorMsg::code()` methods to return a `Result`
+    instead of an `Option` to be consistent with other enum conversion methods
+  - Changed `auction_time` field in `ImbalanceMsg` to be formatted as a timestamp
