+0.5.2 (2018-09-12)
+------------------
+
+Note: This release does NOT change the libsigrokdecode public C API in
+incompatible ways. This means existing frontends should not require any
+changes. However, individual PDs and their output changed, which may
+require some adaptations on the user's side in some cases.
+
+ * New supported protocol decoders:
+   - mcs48            Intel MCS-48 external memory access protocol
