 # OpenXC Message Format Changelog
 
+## v0.5.0-dev
+
+## v0.4
+
+* BREAKING: Removed factor and offset from diagnostic requests to minimize the number of
+  fields, and since this is such an uncommon use case and one that can be
+  handled by the client receiving the data. We may add them back in the future.
+* BREAKING: Require an 'action' to diagnostic request commands, e.g. cancel or add.
+* BREAKING: Rename "raw" messages to the more precise "CAN messages".
+* BREAKING: Rename "translated" messages to "simple messages".
+* BREAKING: Remove redundant `type` field from simple messages (formerly
+  translated messages). The type can be inferred implicitly through the types of
+  the value and event fields.
+* Feature: Add a command for controlling CAN message passthrough.
+* Feature: Add a command for controlling CAN controller acceptance filter bypass.
+* Feature: Add a command to change the payload format.
+* Feature: Add a command to control whether pre-defined, recurring OBD-II
+  requests are enabled.
+* Improvement: Add `extras` field to JSON messages.
+* Improvement: Add an optional 'status' field to all command responses.
+* Improvement: Build protobuf generated files with nanopb v0.3.1.
+* Improvement: Allow explicitly setting CAN message frame format (i.e. standard
+  or extended frame).
+* Fix: Expand range of mode field to a full byte (#10)
+
 ## v0.3
 
 * Add diagnostic message request/response format.
