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: +2009-01-08 version 2.3.0: General * Parsers for repeated numeric fields now always accept both packed and |
