+2008-09-24 version 2.0.2:
+
+ General
+ * License changed from Apache 2.0 to New BSD.
+ * It is now possible to define custom "options", which are basically
+ annotations which may be placed on definitions in a .proto file.
+ For example, you might define a field option called "foo" like so:
+ import "google/protobuf/descriptor.proto"
+ extend google.protobuf.FieldOptions {
+ optional string foo = 12345;
+ }
+ Then you annotate a field using the "foo" option:
+ message MyMessage {
+ optional int32 some_field = 1 [(foo) = "bar"]
+ }
+ The value of this option is then visible via the message's
+ Descriptor:
+ const FieldDescriptor* field =
+ MyMessage::descriptor()->FindFieldByName("some_field");
+ assert(field->options().GetExtension(foo) == "bar");
+ This feature has been implemented and tested in C++ and Java.
+ Other languages may or may not need to do extra work to support
+ custom options, depending on how they construct descriptors.
+
+ C++
+ * Fixed some GCC warnings that only occur when using -pedantic.
+ * Improved static initialization code, making ordering more
+ predictable among other things.
+ * TextFormat will no longer accept messages which contain multiple
+ instances of a singular field. Previously, the latter instance
+ would overwrite the former.
+ * Now works on systems that don't have hash_map.
+
+ Java
+ * Print @Override annotation in generated code where appropriate.
+
+ Python
+ * Strings now use the "unicode" type rather than the "str" type.
+ String fields may still be assigned ASCII "str" values; they will
+ automatically be converted.
+ * Adding a property to an object representing a repeated field now
+ raises an exception. For example:
+ # No longer works (and never should have).
+ message.some_repeated_field.foo = 1
