  • v3.12.3

    June 03, 2020

    Objective-C

    • 👉 Tweak the union used for Extensions to support old generated code. #7573
  • v3.12.2

    May 26, 2020

    C++

    • 🏗 Simplified the template export macros to fix the build for mingw32. (#7539)

    Objective-C

    • 🛠 Fix for the :protobuf_objc target in the Bazel BUILD file. (#7538)
  • v3.12.1

    May 20, 2020

    💎 Ruby

    • 💎 Re-add binary gems for Ruby 2.3 and 2.4. These are EOL upstream, however
      👍 many people still use them and dropping support will require more
      coordination. (#7529, #7531).
  • v3.12.0

    May 15, 2020

    Protocol Compiler

    • 👍 [experimental] Singular, non-message typed fields in proto3 now support
      presence tracking. This is enabled by adding the "optional" field label and
      👍 passing the --experimental_allow_proto3_optional flag to protoc.
    • 👍 Allow duplicate symbol names when multiple descriptor sets are passed on
      the command-line, to match the behavior when multiple .proto files are passed.
    • Deterministic protoc --descriptor_set_out (#7175)

    C++

    • 👍 [experimental] Added proto3 presence support.
    • 🆕 New descriptor APIs to support proto3 presence.
    • 🛠 Fix for #7463 in -rc1 (core dump mixing optional and singular fields in proto3)
    • 0️⃣ Enable Arenas by default on all .proto files.
    • Documented that users are not allowed to subclass Message or MessageLite.
    • Mark generated classes as final; inheriting from protos is strongly discouraged.
    • ➕ Add stack overflow protection for text format with unknown fields.
    • ➕ Add accessors for map key and value FieldDescriptors.
    • ➕ Add FieldMaskUtil::FromFieldNumbers().
    • 📜 MessageDifferencer: use ParsePartial() on Any fields so the diff does not
      fail when there are missing required fields.
    • 🔀 ReflectionOps::Merge(): lookup messages in the right factory, if it can.
    • Added Descriptor::WellKnownTypes enum and Descriptor::well_known_type()
      accessor as an easier way of determining if a message is a Well-Known Type.
    • ⚡️ Optimized RepeatedField::Add() when it is used in a loop.
    • 🚚 Made proto move/swap more efficient.
    • De-virtualize the GetArena() method in MessageLite.
    • Improves performance of json_stream_parser.cc by factor 1000 (#7230)
    • 🐛 bug: #7076 undefine Windows OUT and OPTIONAL macros (#7087)
    • 🛠 Fixed a bug in FieldDescriptor::DebugString() that would erroneously print
      an "optional" label for a field in a oneof.
    • 🛠 Fix bug in parsing bool extensions that assumed they are always 1 byte.
    • 🛠 Fix off-by-one error in FieldOptions::ByteSize() when extensions are present.
    • Clarified the comments to show an example of the difference between
      Descriptor::extension and DescriptorPool::FindAllExtensions.
    • ⚡️ Add a compiler option 'code_size' to force optimize_for=code_size on all
      protos where this is possible.

    Java

    • 👍 [experimental] Added proto3 presence support.
    • 🛠 Fix for #7480 in -rc1 ("TextFormat and JsonFormat ignore experimental proto3 optional enums")
    • 🛠 Fix for #7505 in -rc1 (" toString() returns incorrect ascii when there are duplicate keys in a map")
    • 🗄 Mark java enum _VALUE constants as @deprecated if the enum field is deprecated
    • ⬇️ reduce size for enums with allow_alias set to true.
    • 🖨 Sort map fields alphabetically by the field's key when printing textproto.
    • 🔀 TextFormat.merge() handles Any as top level type.
    • Throw a descriptive IllegalArgumentException when calling
      getValueDescriptor() on enum special value UNRECOGNIZED instead of
      ArrayIndexOutOfBoundsException.
    • 🛠 Fixed an issue with JsonFormat.printer() where setting printingEnumsAsInts()
      🔧 would override the configuration passed into includingDefaultValueFields().
    • Implement overrides of indexOf() and contains() on primitive lists returned
      for repeated fields to avoid autoboxing the list contents.
    • ➕ Add overload to FieldMaskUtil.fromStringList that accepts a descriptor.
    • 🚚 [bazel] Move Java runtime/toolchains into //java (#7190)

    Python

    • 👍 [experimental] Added proto3 presence support.
    • [experimental] fast import protobuf module, only works with cpp generated code linked in.

      implementation (C++ extension was already doing this).
    • 🛠 Fixed a memory leak in C++ bindings.
    • ➕ Added a deprecation warning when code tries to create Descriptor objects
      directly.
    • 🛠 Fix unintended comparison between bytes and string in descriptor.py.
    • 🖨 Avoid printing excess digits for float fields in TextFormat.
