  • v3.10.0

    October 03, 2019

    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.
    • Do not convert unknown field name to snake case to accurately report error.
    • 🛠 Fix a UBSAN warnings. (#6333)
    • ➕ Add podspec for C++ (#6404)
    • protoc: fix source code info location for missing label (#6436)
    • 🚚 C++ Add move constructor for Reflection's SetString (#6477)

    Java

    🚀 This release has a known issue on Android API level <26 (#6718)

    • 🔀 Call loadDescriptor outside of synchronized block to remove one possible source of deadlock.
    • Have oneof enums implement a separate interface (other than EnumLite) for clarity.
    • Opensource Android Memory Accessors
    • ⚡️ Update TextFormat to make use of the new TypeRegistry.
    • 👌 Support getFieldBuilder and getRepeatedFieldBuilder in ExtendableBuilder
    • ⚡️ Update JsonFormat to make use of the new TypeRegistry.
    • ➕ Add proguard config generator for GmmBenchmarkSuiteLite.
    • 🔄 Change ProtobufArrayList to use Object[] instead of ArrayList for 5-10% faster parsing
    • 📜 Implement ProtobufArrayList.add(E) for 20% (5%-40%) faster overall protolite2 parsing
    • 📦 Make a copy of JsonFormat.TypeRegistry at the protobuf top level package. This will eventually replace JsonFormat.TypeRegistry.
    • 🛠 Fix javadoc warnings in generated files (#6231)
    • Java: Add Automatic-Module-Name entries to the Manifest (#6568)

    Python

    JavaScript

    • ✂ Remove deprecated boolean option to getResultBase64String().
    • 🛠 Fix sint64 zig-zag encoding.
    • Simplify hash64 string conversion to avoid DIGIT array. Should reduce overhead if these functions aren't used, and be more efficient by avoiding linear array searches.
    • 🔄 Change the parameter types of binaryReaderFn in ExtensionFieldBinaryInfo to (number, ?, ?).
    • Create dates.ts and time_of_days.ts to mirror Java versions. This is a near-identical conversion of c.g.type.util.{Dates,TimeOfDays} respectively.
    • Migrate moneys to TypeScript.

    • Optimization for layout_init() (#6547)
    • 🛠 Fix for GC of Ruby map frames. (#6533)

    June 26, 2019
  • v3.8.0

    May 28, 2019

    C++

    • 👉 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.
    • 🛠 Fix a mistake, we shouldn't verify map key/value strings for utf8 in opt mode for proto2.
    • Further improvements to cut binary size.
    • 🔀 Prepare to make MergePartialFromCodedStream non-virtual.

    • 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.
    • ⬇️ Reduce linker input. It turns out that ParseMessage is not inlined, producing template instantiations that are used only once and save nothing but cost more.
    • 👌 Improve the parser.
    • 🗄 [c++17] Changed proto2::RepeatedPtrField iterators to no longer derive from the deprecated std::iterator class.

    • ✅ Minor optimization to RopeByteString.PieceIterator

    JavaScript

    • 0️⃣ Simplify generated toObject code when the default value is used.

    Python
