+Nanopb-0.3.5 (2016-xx-xx)
+=========================
+
+Add support for platforms without uint8_t
+-----------------------------------------
+**Rationale:** Some platforms cannot access 8-bit sized values directly, and
+do not define *uint8_t*. Nanopb previously didn't support these platforms.
+
+**Changes:** References to *uint8_t* were replaced with several alternatives,
+one of them being a new *pb_byte_t* typedef. This in turn uses *uint_least8_t*
+which means the smallest available type.
+
+**Required actions:** If your platform does not have a standards-compliant
+*stdint.h*, it may lack the definition for *[u]int_least8_t*. This must be
+added manually, example can be found in *extra/pb_syshdr.h*.
+
+**Error indications:** Compiler error: "unknown type name 'uint_least8_t'".
+
+Nanopb-0.3.2 (2015-01-24)
+=========================
+
+Add support for OneOfs
+----------------------
+**Rationale:** Previously nanopb did not support the *oneof* construct in
+*.proto* files. Those fields were generated as regular *optional* fields.
+
+**Changes:** OneOfs are now generated as C unions. Callback fields are not
+supported inside oneof and generator gives an error.
+
+**Required actions:** The generator option *no_unions* can be used to restore old
+behaviour and to allow callbacks to be used. To use unions, one change is
+needed: use *which_xxxx* field to detect which field is present, instead
+of *has_xxxx*. Compare the value against *MyStruct_myfield_tag*.
+
+**Error indications:** Generator error: "Callback fields inside of oneof are
+not supported". Compiler error: "Message" has no member named "has_xxxx".
