+2009-12-17 version 2.3.0:
+
+  General
+  * Parsers for repeated numeric fields now always accept both packed and
+    unpacked input.  The [packed=true] option only affects serializers.
+    Therefore, it is possible to switch a field to packed format without
+    breaking backwards-compatibility -- as long as all parties are using
+    protobuf 2.3.0 or above, at least.
+  * The generic RPC service code generated by the C++, Java, and Python
+    generators can be disabled via file options:
+      option cc_generic_services = false;
+      option java_generic_services = false;
+      option py_generic_services = false;
+    This allows plugins to generate alternative code, possibly specific to some
+    particular RPC implementation.
+
+  protoc
+  * Now supports a plugin system for code generators.  Plugins can generate
+    code for new languages or inject additional code into the output of other
+    code generators.  Plugins are just binaries which accept a protocol buffer
+    on stdin and write a protocol buffer to stdout, so they may be written in
+    any language.  See src/google/protobuf/compiler/plugin.proto.
+  * inf, -inf, and nan can now be used as default values for float and double
+    fields.
+
+  C++
+  * Various speed and code size optimizations.
+  * DynamicMessageFactory is now fully thread-safe.
+  * Message::Utf8DebugString() method is like DebugString() but avoids escaping
+    UTF-8 bytes.
+  * Compiled-in message types can now contain dynamic extensions, through use
+    of CodedInputStream::SetExtensionRegistry().
+
+  Java
+  * parseDelimitedFrom() and mergeDelimitedFrom() now detect EOF and return
+    false/null instead of throwing an exception.
+  * Fixed some initialization ordering bugs.
+  * Fixes for OpenJDK 7.
+
+  Python
+  * 10-25 times faster than 2.2.0, still pure-Python.
+  * Calling a mutating method on a sub-message always instantiates the message
+    in its parent even if the mutating method doesn't actually mutate anything
+    (e.g. parsing from an empty string).
+  * Expanded descriptors a bit.
