C++

  • Introduced new MOMI (maybe-outside-memory-interval) parser.
  • Add an option to json_util to parse enum as case-insensitive. In the future, enum parsing in json_util will become case-sensitive.
  • Added conformance test for enum aliases
  • Added support for --cpp_out=speed:...
  • Added use of C++ override keyword where appropriate
  • Many other cleanups and fixes.

Java

  • Fix illegal reflective access warning in JDK 9+
  • Add BOM

Python

  • Added Python 3.7 compatibility.
  • Modified ParseFromString to return bytes parsed .
  • Introduce Proto C API.
  • FindFileContainingSymbol in descriptor pool is now able to find field and enum values.
  • reflection.MakeClass() and reflection.ParseMessage() are deprecated.
  • Added DescriptorPool.FindMethodByName() method in pure python (c extension alreay has it)
  • Flipped proto3 to preserve unknown fields by default.
  • Added support for memoryview in python3 proto message parsing.
  • Added MergeFrom for repeated scalar fields in c extension (pure python already has it)
  • Surrogates are now rejected at setters in python3.
  • Added public unknown field API.
  • RecursionLimit is also set to max if allow_oversize_protos is enabled.
  • Disallow duplicate scalars in proto3 text_format parse.
  • Fix some segment faults for c extension map field.

PHP

  • Most issues for json encoding/decoding in the c extension have been fixed. There are still some edge cases not fixed. For more details, check conformance/failure_list_php_c.txt.

  • Allow setting/getting wrapper message fields using primitive values.
  • Various bug fixes.
