+2015-08-26 version 3.0.0-beta-1 (C++/Java/Python/Ruby/Nano/Objective-C/C#/JavaSript)
|
|
|
+ General
|
|
|
+ * Intorduced a new language implementaion: JavaScript.
|
|
|
+ * Added a new field option "json_name". By default proto field names are
|
|
|
+ converted to "lowerCamelCase" in proto3 JSON format. This option can be
|
|
|
+ used to override this behavior and specify a different JSON name for the
|
|
|
+ field.
|
|
|
+ * Added conformance tests to ensure implementations are following proto3 JSON
|
|
|
+ specification.
|
|
|
+
|
|
|
+ C++ (Beta)
|
|
|
+ * Various bug fixes and improvements to the JSON support utility:
|
|
|
+ - Duplicate map keys in JSON are now rejected (i.e., translation will
|
|
|
+ fail).
|
|
|
+ - Fixed wire-format for google.protobuf.Value/ListValue.
|
|
|
+ - Fixed precision loss when converting google.protobuf.Timestamp.
|
|
|
+ - Fixed a bug when parsing invalid UTF-8 code points.
|
|
|
+ - Fixed a memory leak.
|
|
|
+ - Reduced call stack usage.
|
|
|
+
|
|
|
+ Java (Beta)
|
|
|
+ * Cleaned up some unused methods on CodedOutputStream.
|
|
|
+ * Presized lists for packed fields during parsing in the lite runtime to
|
|
|
+ reduce allocations and improve performance.
|
|
|
+ * Improved the performance of unknown fields in the lite runtime.
|
|
|
+ * Introduced UnsafeByteStrings to support zero-copy ByteString creation.
|
|
|
+ * Various bug fixes and improvements to the JSON support utility:
|
|
|
+ - Fixed a thread-safety bug.
|
|
|
+ - Added a new option “preservingProtoFieldNames” to JsonFormat.
|
|
|
+ - Added a new option “includingDefaultValueFields” to JsonFormat.
|
|
|
+ - Updated the JSON utility to comply with proto3 JSON specification.
|
|
|
+
|
|
|
+ Python (Beta)
|
|
|
+ * Added proto3 JSON format utility. It includes support for all field types
|
|
|
+ and a few well-known types except for Any and Struct.
|
|
|
+ * Added runtime support for Any, Timestamp, Duration and FieldMask.
|
|
|
+ * [ ] is now accepted for repeated scalar fields in text format parser.
|
|
|
+
|
|
|
+ Objective-C (Beta)
|
|
|
+ * Various bug-fixes and code tweaks to pass more strict compiler warnings.
|
|
|
+ * Now has conformance test coverage and is passing all tests.
|
|
|
+
|
|
|
+ C# (Beta)
|
|
|
+ * Various bug-fixes.
|
|
|
+ * Code generation: Files generated in directories based on namespace.
|
|
|
+ * Code generation: Include comments from .proto files in XML doc
|
|
|
+ comments (naively)
|
|
|
+ * Code generation: Change organization/naming of "reflection class" (access
|
|
|
+ to file descriptor)
|
|
|
+ * Code generation and library: Add Parser property to MessageDescriptor,
|
|
|
+ and introduce a non-generic parser type.
|
|
|
+ * Library: Added TypeRegistry to support JSON parsing/formatting of Any.
|
|
|
+ * Library: Added Any.Pack/Unpack support.
|
|
|
+ * Library: Implemented JSON parsing.
|
|
|
+
|
|
|
+ Javascript (Alpha)
|
|
|
+ * Added proto3 support for JavaScript. The runtime is written in pure
|
|
|
+ JavaScript and works in browsers and in Node.js. To generate JavaScript
|
|
|
+ code for your proto, invoke protoc with "--js_out". See js/README.md
|
|
|
+ for more build instructions.
