Some memory sanitizers reported them as memory leaks. + + Java + * Updated DynamicMessage.setField() to handle repeated enum values + correctly. + * Fixed a bug that caused NullPointerException to be thrown when + converting manually constructed FileDescriptorProto to + FileDescriptor. + + Python + * Fixed WhichOneof() to work with de-serialized protobuf messages. + * Fixed a missing file problem of Python C++ implementation. + +2014-08-15 version 2.6.0: + + General + * Added oneofs(unions) feature. Fields in the same oneof will share + memory and at most one field can be set at the same time. Use the + oneof keyword to define a oneof like: + message SampleMessage { + oneof test_oneof { + string name = 4; + YourMessage sub_message = 9; + } + } + * Files, services, enums, messages, methods and enum values can be marked + as deprecated now. + * Added Support for list values, including lists of mesaages, when + parsing text-formatted protos in C++ and Java. + For example: foo: [1, 2, 3] + + C++ + * Enhanced customization on TestFormat printing. + * Added SwapFields() in reflection API to swap a subset of fields. + Added SetAllocatedMessage() in reflection API. + * Repeated primitive extensions are now packable. The + [packed=true] option only affects serializers. Therefore, it is + possible to switch a repeated extension field to packed format + without breaking backwards-compatibility. + * Various speed optimizations. + + Java + * writeTo() method in ByteString can now write a substring to an + output stream. Added endWith() method for ByteString. + * ByteString and ByteBuffer are now supported in CodedInputStream + and CodedOutputStream. + * java_generate_equals_and_hash can now be used with the LITE_RUNTIME. + + Python + * A new C++-backed extension module (aka "cpp api v2") that replaces the + old ("cpp api v1") one. Much faster than the pure Python code. This one + resolves many bugs and is recommended for general use over the + pure Python when possible. + * Descriptors now have enum_types_by_name and extension_types_by_name dict + attributes. + * Support for Python 3. + +2013-02-27 version 2.5.0: + + General + * New notion "import public" that allows a proto file to forward the content + it imports to its importers. For example, + // foo.proto + import public "bar.proto"; + import "baz.proto"; + + // qux.proto + import "foo.proto"; + // Stuff defined in bar.proto may be used in this file, but stuff from + // baz.proto may NOT be used without importing it explicitly. + This is useful for moving proto files. To move a proto file, just leave + a single "import public" in the old proto file. + * New enum option "allow_alias" that specifies whether different symbols can + be assigned the same numeric value. Default value is "true". Setting it to + false causes the compiler to reject enum definitions where multiple symbols + have the same numeric value. + Note: We plan to flip the default value to "false" in a future release. + Projects using enum aliases should set the option to "true" in their .proto + files. + + C++ + * New generated method set_allocated_foo(Type* foo) for message and string + fields. This method allows you to set the field to a pre-allocated object + and the containing message takes the ownership of that object. + * Added SetAllocatedExtension() and ReleaseExtension() to extensions API. + * Custom options are now formatted correctly when descriptors are printed in + text format. + * Various speed optimizations. + + Java + * Comments in proto files are now collected and put into generated code as + comments for corresponding classes and data members. + * Added Parser to parse directly into messages without a Builder. For + example, + Foo foo = Foo.PARSER.ParseFrom(input); + Using Parser is ~25% faster than using Builder to parse messages. + * Added getters/setters to access the underlying ByteString of a string field + directly. + * ByteString now supports more operations: substring(), prepend(), and + append(). The implementation of ByteString uses a binary tree structure + to support these operations efficiently. + * New method findInitializationErrors() that lists all missing required + fields. + * Various code size and speed optimizations. + + Python + * Added support for dynamic message creation. DescriptorDatabase, + DescriptorPool, and MessageFactory work like their C++ couterparts to + simplify Descriptor construction from *DescriptorProtos, and MessageFactory + provides a message instance from a Descriptor. + * Added pickle support for protobuf messages. + * Unknown fields are now preserved after parsing. + * Fixed bug where custom options were not correctly populated. Custom + options can be accessed now. + * Added EnumTypeWrapper that provides better accessibility to enum types. + * Added ParseMessage(descriptor, bytes) to generate a new Message instance + from a descriptor and a byte string. + +2011-05-01 version 2.4.1: + + C++ + * Fixed the frendship problem for old compilers to make the library now gcc 3 + compatible again. + * Fixed vcprojects/extract_includes.bat to extract compiler/plugin.h. + + Java + * Removed usages of JDK 1.6 only features to make the library now JDK 1.5 + compatible again. + * Fixed a bug about negative enum values. + * serialVersionUID is now defined in generated messages for java serializing. + * Fixed protoc to use java.lang.Object, which makes "Object" now a valid + message name again. + + Python + * Experimental C++ implementation now requires C++ protobuf library installed. + See the README.txt in the python directory for details. + +2011-02-02 version 2.4.0: + + General + * The RPC (cc|java|py)_generic_services default value is now false instead of + true. + * Custom options can have aggregate types. For example, + message MyOption { + optional string comment = 1; + optional string author = 2; + } + extend google.protobuf.FieldOptions { + optional MyOption myoption = 12345; + } + This option can now be set as follows: + message SomeType { + optional int32 field = 1 [(myoption) = { comment:'x' author:'y' }]; + } + + C++ + * Various speed and code size optimizations. + * Added a release_foo() method on string and message fields. + * Fixed gzip_output_stream sub-stream handling. + + Java + * Builders now maintain sub-builders for sub-messages. Use getFooBuilder() to + get the builder for the sub-message "foo". This allows you to repeatedly + modify deeply-nested sub-messages without rebuilding them. + * Builder.build() no longer invalidates the Builder for generated messages + (You may continue to modify it and then build another message). + * Code generator will generate efficient equals() and hashCode() + implementations if new option java_generate_equals_and_hash is enabled. + (Otherwise, reflection-based implementations are used.) + * Generated messages now implement Serializable. + * Fields with [deprecated=true] will be marked with @Deprecated in Java. + * Added lazy conversion of UTF-8 encoded strings to String objects to improve + performance. + * Various optimizations. + * Enum value can be accessed directly, instead of calling getNumber() on the + enum member. + * For each enum value, an integer constant is also generated with the suffix + _VALUE. + + Python + * Added an experimental C++ implementation for Python messages via a Python + extension. Implementation type is controlled by an environment variable + PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION (valid values: "cpp" and "python") + The default value is currently "python" but will be changed to "cpp" in + future release. + * Improved performance on message instantiation significantly. + Most of the work on message instantiation is done just once per message + class, instead of once per message instance. + * Improved performance on text message parsing. + * Allow add() to forward keyword arguments to the concrete class. + E.g. instead of + item = repeated_field.add() + item.foo = bar + item.baz = quux + You can do: + repeated_field.add(foo=bar, baz=quux) + * Added a sort() interface to the BaseContainer. + * Added an extend() method to repeated composite fields. + * Added UTF8 debug string support. + +2010-01-08 version 2.3.0: General * Parsers for repeated numeric fields now always accept both packed and |
