+- Update to version 1.1.0:
+  + Fix a bug when merging optional byte fields.
+  + Documentation updates.
+  + Implement oneof support (Issue #174). Protobuf 2.6.0 or newer
+    is now required to build protobuf-c.
+  + Print leading comments for enum, message, and field definitions
+    into generated header files (Issue #175).
+- Changes from version 1.0.2:
+  + Fix a build failure with Protobuf 2.6.0 related to aliased enum
+    constants (Issue #163).
+  + Protobuf 2.5.0 or newer is now required to build protobuf-c
+    (Issue #166). This is due to the fix for #163.
+  + Eliminate void pointer arithmetic (Issue #167).
+  + Always define PROTOBUF_C__DEPRECATED, even on compilers that
+    are not GCC (Issue #167).
+  + Work around the lack of the 'inline' keyword in Microsoft
+    compilers (Issue #167).
+  + Add a CMakeLists.txt file as a fallback build system for
+    Windows (Issue #168).
+  + Fix a build failure in the test suite that occurred with a
+    parallel make running on a system with a large number of CPUs
+    (Issue #156, #169).
+- Changes from version 1.0.1:
+  + Explicitly set the .data field of ProtobufCBinaryData's to NULL
+    when unpacking a zero length byte string (Issue #157).
+- For a list of changes between 0.15 and 1.0.0, please refer to the
+  extensive ChangeLog file.
+- Bump soname to 1, following upstream.
+- Update Url tag: project moved over to github.
+- Update license to be BSD-3-Clause and install LICENSE file.
