* Dropped support for netstandard1.0 (replaced by support for netstandard1.1). This was required to modernize the parsing stack to use the `Span` type internally
* Add `ParseFrom(ReadOnlySequence)` method to enable GC friendly parsing with reduced allocations and buffer copies
* Add support for serialization directly to a `IBufferWriter` or to a `Span` to enable GC friendly serialization. The new API is available as extension methods on the `IMessage` type
* 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
* Due to the major overhaul of parsing and serialization internals, 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).

* Wed Jun 10 2020 Rolf Krahl - Python: Add requirement on python-six
* Fri Mar 06 2020 Nico Kruber - Update to version 3.11.4; notable changes since 3.9.2:
* C++: Make serialization method naming consistent
* C++: Moved ShutdownProtobufLibrary() to message_lite.h. For backward compatibility a declaration is still available in stubs/common.h, but users should prefer message_lite.h
* C++: Removed non-namespace macro EXPECT_OK()
* C++: Removed mathlimits.h from stubs in favor of using std::numeric_limits from C++11
* C++: Support direct pickling of nested messages
* C++: Disable extension code gen for C#
* C++: Switch the proto parser to the faster MOMI parser
* C++: Unused imports of files defining descriptor extensions will now be reported
* C++: Add proto2::util::RemoveSubranges to remove multiple subranges in linear time
* C++: Support 32 bit values for ProtoStreamObjectWriter to Struct
* C++: Removed the internal-only header coded_stream_inl.h and the internal-only methods defined there
* C++: Enforced no SWIG wrapping of descriptor_database.h (other headers already had this restriction)
* C++: 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
* C++: Add move constructor for Reflection\'s SetString
* Java: Remove the usage of MethodHandle, so that Android users prior to API version 26 can use protobuf-java
* Java: Publish ProGuard config for javalite
* Java: Include unknown fields when merging proto3 messages in Java lite builders
* Java: Have oneof enums implement a separate interface (other than EnumLite) for clarity
* Java: Opensource Android Memory Accessors
* Java: Change ProtobufArrayList to use Object[] instead of ArrayList for 5-10% faster parsing
* Java: Make a copy of JsonFormat.TypeRegistry at the protobuf top level package. This will eventually replace JsonFormat.TypeRegistry
* Java: Add Automatic-Module-Name entries to the Manifest
* Python: Add float_precision option in json format printer
* Python: Optionally print bytes fields as messages in unknown fields, if possible
* Python: Experimental code gen (fast import protobuf module) which only work with cpp generated code linked in
* Python: Add descriptor methods in descriptor_pool are deprecated
* Python: Added delitem for Python extension dict
* JavaScript: Remove guard for Symbol iterator for jspb.Map
* JavaScript: Remove deprecated boolean option to getResultBase64String()
* JavaScript: Change the parameter types of binaryReaderFn in ExtensionFieldBinaryInfo to (number, ?, ?)
* JavaScript: 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
* JavaScript: Migrate moneys to TypeScript
* PHP: Increase php7.4 compatibility
* PHP: Implement lazy loading of php class for proto messages
* Ruby: Support hashes for struct initializers
* C#: Experimental proto2 support is now officially available
* C#: Change _Extensions property to normal body rather than expression

* due to alignment requirements
