Java

  • Refactoring java full runtime to reuse sub-message builders and prepare to
    migrate parsing logic from parse constructor to builder.
  • Move proto wireformat parsing functionality from the private "parsing
    constructor" to the Builder class.

    messages rather than building up a new immutable object before merging. This
    way results in fewer allocations and copy operations.
  • Make message-type extensions merge from wire-format instead of building up
    instances and merging afterwards. This has much better performance.

    sub-messages directly from text rather than building a new sub-message and
    merging the fully formed message into the existing field.

  • Added Ruby 3.1 support for CI and releases (#9566).
  • Message.decode/encode: Add recursion_limit option (#9218/#9486)

    frequent GC runs (#9586).

  • Suppress warning for intentional circular require (#9556)
  • JSON will now output shorter strings for double and float fields when possible

    systems.
  • UTF-8 verification was fixed to properly reject surrogate code points.
  • Unknown enums for proto2 protos now properly implement proto2's behavior of
    putting such values in unknown fields.

    in type annotations.
    *[Breaking change] Protobuf python generated codes are simplified. Descriptors and message
    classes' definitions are now dynamic created in internal/builder.py.
    Insertion Points for messages classes are discarded.

    zone. If omitted or None, the function returns a timezone-naive UTC datetime
    (as previously).

PHP

  • The C extension is completely rewritten. The new C extension has significantly
    better parsing performance and fixes a handful of conformance issues. It will
    also make it easier to add support for more features like proto2 and proto3 presence.
  • The new C extension does not support PHP 5.x, which is the reason for the major
    version bump. PHP 5.x users can still use pure-PHP.

C++

  • Removed deprecated unsafe arena string accessors
  • Enabled heterogeneous lookup for std::string keys in maps.
  • Removed implicit conversion from StringPiece to std::string
  • Fix use-after-destroy bug when the Map is allocated in the arena.
  • Improved the randomness of map ordering
  • Added stack overflow protection for text format with unknown fields
  • Use std::hash for proto maps to help with portability.
  • Added more Windows macros to proto whitelist.
  • Arena constructors for map entry messages are now marked "explicit"
    (for regular messages they were already explicit).
  • Fix subtle aliasing bug in RepeatedField::Add
  • Fix mismatch between MapEntry ByteSize and Serialize with respect to unset
    fields.

Python

  • JSON format conformance fixes:
    • Reject lowercase t for Timestamp json format.
    • Print full_name directly for extensions (no camelCase).
    • Reject boolean values for integer fields.
    • Reject NaN, Infinity, -Infinity that is not quoted.
    • Base64 fixes for bytes fields: accept URL-safe base64 and missing padding.
  • Bugfix for fields/files named "async" or "await".
  • Improved the error message when AttributeError is returned from getattr
    in EnumTypeWrapper.

Java

  • Fixed a bug where setting optional proto3 enums with setFooValue() would
    not mark the value as present.
  • Add Subtract function to FieldMaskUtil.

C#

  • Dropped support for netstandard1.0 (replaced by support for netstandard1.1).
    This was required to modernize the parsing stack to use the Span<byte>
    type internally. (#7351)
  • Add ParseFrom(ReadOnlySequence<byte>) method to enable GC friendly
    parsing with reduced allocations and buffer copies. (#7351)
  • Add support for serialization directly to a IBufferWriter<byte> or
    to a Span<byte> to enable GC friendly serialization.
    The new API is available as extension methods on the IMessage type. (#7576)
  • Add GOOGLE_PROTOBUF_REFSTRUCT_COMPATIBILITY_MODE define to make
    generated code compatible with old C# compilers (pre-roslyn compilers
    from .NET framework and old versions of mono) that do not support
    ref structs. Users that are still on a legacy stack that does
    not support C# 7.2 compiler might need to use the new define
    in their projects to be able to build the newly generated code. (#7490)
  • Due to the major overhaul of parsing and serialization internals (#7351 and #7576),
    it is recommended to regenerate your generated code to achieve the best
    performance (the legacy generated code will still work, but might incur
    a slight performance penalty).

C++

  • Switch the proto parser to the faster MOMI parser.
  • Properly escape Struct keys in the proto3 JSON serializer.
  • Fix crash on uninitialized map entries.
  • Informed the compiler of has-bit invariant to produce better code
  • Unused imports of files defining descriptor extensions will now be reported
  • Add proto2::util::RemoveSubranges to remove multiple subranges in linear time.
  • Added BaseTextGenerator::GetCurrentIndentationSize()
  • Made implicit weak fields compatible with the Apple linker
  • Support 32 bit values for ProtoStreamObjectWriter to Struct.
  • Removed the internal-only header coded_stream_inl.h and the internal-only methods defined there.
  • Enforced no SWIG wrapping of descriptor_database.h (other headers already had this restriction).
  • Implementation of the equivalent of the MOMI parser for serialization. This removes one of the two serialization routines, by making the fast array serialization routine completely general. SerializeToCodedStream can now be implemented in terms of the much much faster array serialization. The array serialization regresses slightly, but when array serialization is not possible this wins big.

  • Change the parameter types of binaryReaderFn in ExtensionFieldBinaryInfo to (number, ?, ?).

  • Use std::atomic in case of myriad2 platform
  • Always declare enums to be int-sized
  • Added DebugString() and ShortDebugString() methods on MessageLite

  • Move to an internal MACRO for parser validity checks.
  • Improve map parsing performance.
  • Make MergePartialFromCodedStream non virtual. This allows direct calls, potential inlining and is also a code health improvement
  • Add an overall limit to parse_context to prevent reading past it. This allows to remove a annoying level of indirection.

  • Simplify end check.
  • Add overload for ParseMessage for MessageLite/Message types. If the explicit type is not known inlining won't help de-virtualizing the virtual call.

  • Added iter and contains to extension dict
  • Added allow_unknown_field option in python text format parser
  • Fixed Timestamp.ToDatetime() loses precision issue
