The deterministic + serialization guarantees that given a binary, equal messages will be + serialized to the same bytes. This allows applications like MapReduce to + group equal messages based on the serialized bytes. The deterministic + serialization is, however, NOT canonical across languages; it is also + unstable across different builds with schema changes due to unknown fields. + Users who need canonical serialization, e.g. persistent storage in a + canonical form, fingerprinting, etc, should define their own + canonicalization specification and implement the serializer using reflection + APIs rather than relying on this API. + * Added OneofOptions. You can now define custom options for oneof groups. + import "google/protobuf/descriptor.proto"; + extend google.protobuf.OneofOptions { + optional int32 my_oneof_extension = 12345; + } + message Foo { + oneof oneof_group { + (my_oneof_extension) = 54321; + ... + } + } + + C++ (beta) + * Introduced a deterministic serialization API in + CodedOutputStream::SetSerializationDeterministic(bool).

See the notes about + deterministic serialization in the General section. + * File option "java_generate_equals_and_hash" is now deprecated. equals() and + hashCode() methods are generated by default. + * Added a new JSON printer option "omittingInsignificantWhitespace" to produce + a more compact JSON output. The printer will pretty-print by default. + * Updated Java runtime to be compatible with 2.5.0/2.6.1 generated protos. + + Python (beta) + * Added support to pretty print Any messages in text format. + * Added a flag to ignore unknown fields when parsing JSON. + * Bugfix: "@type" field of a JSON Any message is now correctly put before + other fields. + + Objective-C (beta) + * Updated the code to support compiling with more compiler warnings + enabled. (Issue 1616) + * Exposing more detailed errors for parsing failures. (PR 1623) + * Small (breaking) change to the naming of some methods on the support classes + for map<>. There were collisions with the system provided KVO support, so + the names were changed to avoid those issues. (PR 1699) + * Fixed for proper Swift bridging of error handling during parsing. (PR 1712) + * Complete support for generating sources that will go into a Framework and + depend on generated sources from other Frameworks.
