+2019-04-29 version 3.8.0 (C++/Java/Python/PHP/Objective-C/C#/Ruby/JavaScript)
+
+ C++
+ * Use std::atomic<int32> in case of myriad2 platform
+ * Always declare enums to be int-sized
+ * Added DebugString() and ShortDebugString() methods on MessageLite
+ * Specialized different parse loop control flows
+ * Make hasbits potentially in register. The or's start forming an obstacle because it's a read modify store on the same mem address on each iteration.
+ * 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.
+ * A report on some interesting behavior change in python (caused by b/27494216) made me realize there is a check that needs to be done in case the parse ended on a end group tag.
+ * Add a note of caution to the comments around skip in CodedOutputStream.
+ * 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.
+ * Change the default value of case_insensitive_enum_parsing to false for JsonStringToMessage.
+ * Add a warning if a field name doesn't match the style guide.
+ * Fix TextFormat not round-trip correctly when float value is max float.
+ * Added locationed info for some errors at compiler
+ * Python reserved keywords are now working with getattr()/setattr() for most descriptors.
+ * Added AllowUnknownField() in text_format
+ * Append '_' to C++ reserved keywords for message, enum, extension
+ * Fix MSVC warning C4244 in protobuf's parse_context.h.
+ * Updating Iterators to be compatible with C++17 in MSVC.
+ * Use capability annotation in mutex.h
+ * Fix "UndefinedBehaviorSanitizer: cfi-bad-type"
+ * CriticalSectionLock class as a lightweight replacement for std::mutex on Windows platforms.
+ * Removed vestigial wire_format_lite_inl.h
+
+ C#
+ * Added System.Memory dependency.
+
+ Java
+ * Make Java protoc code generator ignore optimize_for LITE_RUNTIME. Users should instead use the Java lite protoc plugin.
+ * Change Extension getMessageDefaultInstance() to return Message instead of MessageLite.
+ * Prevent malicious input streams from leaking buffers for ByteString or ByteBuffer parsing.
+ * Release new Javalite runtime.
+ * Show warning in case potential file name conflict.
+ * Allow Java reserved keywords to be used in extensions.
+ * Added setAllowUnknownFields() in text format
+ * Add memoization to ExtensionRegistryLite.getEmptyRegistry()
+ * Improve performance of CodedOutputStream.writeUInt32NoTag
+ * Add an optimized mismatch-finding algorithm to UnsafeUtil.
+ * When serializing uint32 varints, check that we have MAX_VARINT32_SIZE bytes left, not just MAX_VARINT_SIZE.
+ * Minor optimization to RopeByteString.PieceIterator
+
+ JavaScript
+ * Simplify generated toObject code when the default value is used.
+
+ Python
+ * Changes implementation of Name() for enums that allow aliases in proto2 in Python to be in line with claims in C++ implementation (to return first value).
+ * Added double_format option in text format printer.
+ * Added iter and __contains__ to extension dict
+ * Added allow_unknown_field option in python text format parser
+ * Fixed Timestamp.ToDatetime() loses precision issue
+ * Support unknown field in text format printer.
+ * Float field will be convert to inf if bigger than struct.unpack('f', b'\xff\xff\x7f\x7f')[0] which is about 3.4028234664e+38,
+ convert to -inf if smaller than -3.4028234664e+38
+ * Allowed casting str->bytes in Message.__setstate__
+
+ Ruby
+ * Helper methods to get enum name for Ruby.
