|
|
|
|
Planned Future Changes |
|
|
|
|
* Make C++ implementation C++11 only: we plan to require C++11 to build |
|
|
|
|
protobuf code starting from 3.6.0 release. Please join this github issue: |
|
|
|
|
https://github.com/google/protobuf/issues/2780 to provide your feedback. |

|
General |
|
|
|
|
* Unknown fields are now preserved in proto3 for most of the language |
|
|
|
|
implementations for proto3 by default. See the per-language section for |
|
|
|
|
details. |
|
|
|
|
* reserve keyword are now supported in enums |
|
|
|
|
|
|
|
|
|
C++ |
|
|
|
|
* Proto3 messages are now preserving unknown fields by default. If you rely on |
|
|
|
|
unknowns fields being dropped. Please use DiscardUnknownFields() explicitly. |
|
|
|
|
* Deprecated the unsafe_arena_release_* and unsafe_arena_add_allocated_* |
|
|
|
|
methods for string fields. |
|
|
|
|
* Added move constructor and move assignment to RepeatedField, |
|
|
|
|
RepeatedPtrField and google::protobuf::Any. |
|
|
|
|
* Added perfect forwarding in Arena::CreateMessage |
|
|
|
|
* In-progress experimental support for implicit weak fields with lite protos. |
|
|
|
|
This feature allows the linker to strip out more unused messages and reduce |
|
|
|
|
binary size. |
|
|
|
|
* Various performance optimizations. |

|
Java |
|
|
|
|
* Proto3 messages are now preserving unknown fields by default. If you’d like |
|
|
|
|
to drop unknown fields, please use the DiscardUnknownFieldsParser API. For |
|
|
|
|
example: |
|
|
|
|
Parser<Foo> parser = DiscardUnknownFieldsParser.wrap(Foo.parser()); |
|
|
|
|
Foo foo = parser.parseFrom(input); |
|
|
|
|
* Added a new CodedInputStream decoder for Iterable<ByteBuffer> with direct |
|
|
|
|
ByteBuffers. |
|
|
|
|
* TextFormat now prints unknown length-delimited fields as messages if |
|
|
|
|
possible. |
|
|
|
|
* FieldMaskUtil.merge() no longer creates unnecessary empty messages when a |
|
|
|
|
message field is unset in both source message and destination message. |
|
|
|
|
* Various performance optimizations. |
|
|
|
|
|
|
|
|
|
Python |
|
|
|
|
* Proto3 messages are now preserving unknown fields by default. Use |
|
|
|
|
message.DiscardUnknownFields() to drop unknown fields. |
|
|
|
|
* Add FieldDescriptor.file in generated code. |
|
|
|
|
* Add descriptor pool FindOneofByName in pure python. |
|
|
|
|
* Change unknown enum values into unknown field set . |
|
|
|
|
* Add more Python dict/list compatibility for Struct/ListValue. |
|
|
|
|
* Add utf-8 support for text_format.Merge()/Parse(). |
|
|
|
|
* Support numeric unknown enum values for proto3 JSON format. |
|
|
|
|
* Add warning for Unexpected end-group tag in cpp extension. |
|
|
|
|
|
|
|
|
|
PHP |
|
|
|
|
* Proto3 messages are now preserving unknown fields. |
|
|
|
|
* Provide well known type messages in runtime. |
|
|
|
|
* Add prefix ‘PB’ to generated class of reserved names. |
|
|
|
|
* Fixed all conformance tests for encode/decode json in php runtime. C |
|
|
|
|
extension needs more work. |
|
|
|
|
|
|
|
|
|
Objective-C |
|
|
|
|
* Fixed some issues around copying of messages with unknown fields and then |
|
|
|
|
mutating the unknown fields in the copy. |
|
|
|
|
|
|
|
|
|
C# |
|
|
|
|
* Added unknown field support in JsonParser. |
|
|
|
|
* Fixed oneof message field merge. |

|
|
|
|
|
Ruby |
|
|
|
|
* Unknown fields are now preserved by default. |
|
|
|

|
|
* Decoder can handle both paced and unpacked data no matter how the proto is |
|
|
|
|
defined. |
|
