Users can import and use these protos just like"," regular proto files. Addtional runtime support will be added for them in"," future releases (in the form of utility helper functions, or having them"," replaced by language specific types in generated code)."," * Added a \"reserved\" keyword in both proto2 and proto3 syntax. User can use"," this keyword to declare reserved field numbers and names to prevent them"," from being reused by other fields in the same message.",""," To reserve field numbers, add a reserved declaration in your message:",""," message TestMessage {"," reserved 2, 15, 9 to 11, 3;"," }",""," This reserves field numbers 2, 3, 9, 10, 11 and 15. If a user uses any of"," these as field numbers, the protocol buffer compiler will report an error.",""," Field names can also be reserved:",""," message TestMessage {"," reserved \"foo\", \"bar\";"," }",""," * Various bug fixes since 3.0.0-alpha-2",""," Objective-C"," Objective-C includes a code generator and a native objective-c runtime"," library. By adding “--objc_out†to protoc, the code generator will generate"," a header(*.pbobjc.h) and an implementation file(*.pbobjc.m) for each proto"," file.",""," In this first release, the generated interface provides: enums, messages,"," field support(single, repeated, map, oneof), proto2 and proto3 syntax"," support, parsing and serialization. It’s compatible with ARC and non-ARC"," usage. Besides, user can also access it via the swift bridging header.",""," See objectivec/README.md for details.",""," C#"," * C# protobufs are based on project"," https://github.com/jskeet/protobuf-csharp-port. The original project was"," frozen and all the new development will happen here."," * Codegen plugin for C# was completely rewritten to C++ and is now an"," intergral part of protoc."," * Some refactorings and cleanup has been applied to the C# runtime library."," * Only proto2 is supported in C# at the moment, proto3 support is in"," progress and will likely bring significant breaking changes to the API.",""," See csharp/README.md for details.",""," C++"," * Added runtime support for Any type. To use Any in your proto file, first"," import the definition of Any:",""," // foo.proto"," import \"google/protobuf/any.proto\";"," message Foo {"," google.protobuf.Any any_field = 1;"," }"," message Bar {"," int32 value = 1;"," }",""," Then in C++ you can access the Any field using PackFrom()/UnpackTo()"," methods:",""," Foo foo;"," Bar bar = ...;"," foo.mutable_any_field()-\u003ePackFrom(bar);"," ..."," if (foo.any_field().IsType\u003cBar\u003e()) {"," foo.any_field().UnpackTo(\u0026bar);"," ..."," }"," * In text format, entries of a map field will be sorted by key.",""," Java"," * Continued optimizations on the lite runtime to improve performance for"," Android.",""," Python"," * Added map support."," - maps now have a dict-like interface (msg.map_field[key] = value)"," - existing code that modifies maps via the repeated field interface"," will need to be updated.",""," Ruby"," * Improvements to RepeatedField's emulation of the Ruby Array API."," * Various speedups and internal cleanups.","","2015-02-26 version 3.0.0-alpha-2 (Python/Ruby/JavaNano):"," General"," * Introduced three new language implementations (Ruby, JavaNano, and"," Python) to proto3."," * Various bug fixes since 3.0.0-alpha-1",""," Python:"," Python has received several updates, most notably support for proto3"," semantics in any .proto file that declares syntax=\"proto3\"."," Messages declared in proto3 files no longer represent field presence"," for scalar fields (number, enums, booleans, or strings). You can"," no longer call HasField() for such fields, and they are serialized"," based on whether they have a non-zero/empty/false value.",""," One other notable change is in the C++-accelerated implementation."," Descriptor objects (which describe the protobuf schema and allow"," reflection over it) are no longer duplicated between the Python"," and C++ layers. The Python descriptors are now simple wrappers"," around the C++ descriptors. This change should significantly"," reduce the memory usage of programs that use a lot of message"," types.",""," Ruby:"," We have added proto3 support for Ruby via a native C extension.",""," The Ruby extension itself is included in the ruby/ directory, and details on"," building and installing the extension are in ruby/README.md. The extension"," will also be published as a Ruby gem. Code generator support is included as"," part of `protoc` with the `--ruby_out` flag.",""," The Ruby extension implements a user-friendly DSL to define message types"," (also generated by the code generator from `.proto` files). Once a message"," type is defined, the user may create instances of the message that behave in"," ways idiomatic to Ruby. For example:",""," - Message fields are present as ordinary Ruby properties (getter method"," `foo` and setter method `foo=`)."," - Repeated field elements are stored in a container that acts like a native"," Ruby array, and map elements are stored in a container that acts like a"," native Ruby hashmap."," - The usual well-known methods, such as `#to_s`, `#dup`, and the like, are"," present.",""," Unlike several existing third-party Ruby extensions for protobuf, this"," extension is built on a \"strongly-typed\" philosophy: message fields and"," array/map containers will throw exceptions eagerly when values of the"," incorrect type are inserted.",""," See ruby/README.md for details.",""," JavaNano:"," JavaNano is a special code generator and runtime library designed especially"," for resource-restricted systems, like Android. It is very resource-friendly"," in both the amount of code and the runtime overhead. Here is an an overview"," of JavaNano features compared with the official Java protobuf:",""," - No descriptors or message builders."," - All messages are mutable; fields are public Java fields."," - For optional fields only, encapsulation behind setter/getter/hazzer/"," clearer functions is opt-in, which provide proper 'has' state support."," - For proto2, if not opted in, has state (field presence) is not available."," Serialization outputs all fields not equal to their defaults."," The behavior is consistent with proto3 semantics."," - Required fields (proto2 only) are always serialized."," - Enum constants are integers; protection against invalid values only"," when parsing from the wire."," - Enum constants can be generated into container interfaces bearing"," the enum's name (so the referencing code is in Java style)."," - CodedInputByteBufferNano can only take byte[] (not InputStream)."," - Similarly CodedOutputByteBufferNano can only write to byte[]."," - Repeated fields are in arrays, not ArrayList or Vector. Null array"," elements are allowed and silently ignored."," - Full support for serializing/deserializing repeated packed fields."," - Support extensions (in proto2)."," - Unset messages/groups are null, not an immutable empty default"," instance."," - toByteArray(...) and mergeFrom(...) are now static functions of"," MessageNano."," - The 'bytes' type translates to the Java type byte[].",""," See javanano/README.txt for details.","","2014-12-01 version 3.0.0-alpha-1 (C++/Java):",""," General"," * Introduced Protocol Buffers language version 3 (aka proto3).",""," When protobuf was initially opensourced it implemented Protocol Buffers"," language version 2 (aka proto2), which is why the version number"," started from v2.0.0. From v3.0.0, a new language version (proto3) is"," introduced while the old version (proto2) will continue to be supported.",""," The main intent of introducing proto3 is to clean up protobuf before"," pushing the language as the foundation of Google's new API platform."," In proto3, the language is simplified, both for ease of use and to"," make it available in a wider range of programming languages. At the"," same time a few features are added to better support common idioms"," found in APIs.",""," The following are the main new features in language version 3:",""," 1. Removal of field presence logic for primitive value fields, removal"," of required fields, and removal of default values. This makes proto3"," significantly easier to implement with open struct representations,"," as in languages like Android Java, Objective C, or Go."," 2. Removal of unknown fields."," 3. Removal of extensions, which are instead replaced by a new standard"," type called Any."," 4. Fix semantics for unknown enum values."," 5. Addition of maps."," 6. Addition of a small set of standard types for representation of time,"," dynamic data, etc."," 7. A well-defined encoding in JSON as an alternative to binary proto"," encoding.",""," This release (v3.0.0-alpha-1) includes partial proto3 support for C++ and"," Java. Items 6 (well-known types) and 7 (JSON format) in the above feature"," list are not impelmented.",""," A new notion \"syntax\" is introduced to specify whether a .proto file"," uses proto2 or proto3:",""," // foo.proto"," syntax = \"proto3\";"," message Bar {...}",""," If omitted, the protocol compiler will generate a warning and \"proto2\" will"," be used as the default. This warning will be turned into an error in a"," future release.",""," We recommend that new Protocol Buffers users use proto3. However, we do not"," generally recommend that existing users migrate from proto2 from proto3 due"," to API incompatibility, and we will continue to support proto2 for a long"," time.",""," * Added support for map fields (implemented in C++/Java for both proto2 and"," proto3).",""," Map fields can be declared using the following syntax:",""," message Foo {"," map\u003cstring, string\u003e values = 1;"," }",""," Data of a map field will be stored in memory as an unordered map and it"," can be accessed through generated accessors.",""," C++"," * Added arena allocation support (for both proto2 and proto3).",""," Profiling shows memory allocation and deallocation constitutes a significant"," fraction of CPU-time spent in protobuf code and arena allocation is a"," technique introduced to reduce this cost. With arena allocation, new"," objects will be allocated from a large piece of preallocated memory and"," deallocation of these objects is almost free. Early adoption shows 20% to"," 50% improvement in some Google binaries.",""," To enable arena support, add the following option to your .proto file:",""," option cc_enable_arenas = true;",""," Protocol compiler will generate additional code to make the generated"," message classes work with arenas. This does not change the existing API"," of protobuf messages and does not affect wire format. Your existing code"," should continue to work after adding this option. In the future we will"," make this option enabled by default.",""," To actually take advantage of arena allocation, you need to use the arena"," APIs when creating messages. A quick example of using the arena API:",""," {"," google::protobuf::Arena arena;"," // Allocate a protobuf message in the arena."," MyMessage* message = Arena::CreateMessage\u003cMyMessage\u003e(\u0026arena);"," // All submessages will be allocated in the same arena."," if (!message-\u003eParseFromString(data)) {"," // Deal with malformed input data."," }"," // Must not delete the message here. It will be deleted automatically"," // when the arena is destroyed."," }",""," Currently arena does not work with map fields. Enabling arena in a .proto"," file containing map fields will result in compile errors in the generated"," code. This will be addressed in a future release.","","2014-10-20 version 2.6.1:",""," C++"," * Added atomicops support for Solaris."," * Released memory allocated by InitializeDefaultRepeatedFields() and"," GetEmptyString().

Within"," this blob, the individual values are encoded the same way they would"," be normally except without a tag before each value (thus, they are"," tightly \"packed\")."," * For each field, the generated code contains an integer constant assigned"," to the field number. For example, the .proto file:"," message Foo { optional int bar_baz = 123; }"," would generate the following constants, all with the integer value 123:"," C++: Foo::kBarBazFieldNumber"," Java: Foo.BAR_BAZ_FIELD_NUMBER"," Python: Foo.BAR_BAZ_FIELD_NUMBER"," Constants are also generated for extensions, with the same naming scheme."," These constants may be used as switch cases."," * Updated bundled Google Test to version 1.3.0.

For a service"," Foo, Foo.Interface is a pure interface containing all of the service's"," defined methods. Foo.newReflectiveService() can be called to wrap an"," instance of this interface in a class that implements the generic"," RpcService interface, which provides reflection support that is usually"," needed by RPC server implementations."," * RPC interfaces now support blocking operation in addition to non-blocking."," The protocol compiler generates separate blocking and non-blocking stubs"," which operate against separate blocking and non-blocking RPC interfaces."," RPC implementations will have to implement the new interfaces in order to"," support blocking mode."," * New I/O methods parseDelimitedFrom(), mergeDelimitedFrom(), and"," writeDelimitedTo() read and write \"delemited\" messages from/to a stream,"," meaning that the message size precedes the data.
