+2015-05-25 version 3.0.0-alpha-3 (Objective-C/C#):
+  General
+  * Introduced two new language implementations (Objective-C, C#) to proto3.
+  * Explicit "optional" keyword are disallowed in proto3 syntax, as fields are
+    optional by default.
+  * Group fields are no longer supported in proto3 syntax.
+  * Changed repeated primitive fields to use packed serialization by default in
+    proto3 (implemented for C++, Java, Python in this release).  The user can
+    still disable packed serialization by setting packed to false for now.
+  * Added well-known type protos (any.proto, empty.proto, timestamp.proto,
+    duration.proto, etc.). Users can import and use these protos just like
+    regular proto files. Addtional runtime support will be added for them in
+    future releases (in the form of utility helper functions, or having them
+    replaced by language specific types in generated code).
+  * Added a "reserved" keyword in both proto2 and proto3 syntax. User can use
+    this keyword to declare reserved field numbers and names to prevent them
+    from being reused by other fields in the same message.
+
+    To reserve field numbers, add a reserved declaration in your message:
+
+      message TestMessage {
+        reserved 2, 15, 9 to 11, 3;
+      }
+
+    This reserves field numbers 2, 3, 9, 10, 11 and 15. If a user uses any of
+    these as field numbers, the protocol buffer compiler will report an error.
+
+    Field names can also be reserved:
+
+      message TestMessage {
+        reserved "foo", "bar";
+      }
+
+  * Various bug fixes since 3.0.0-alpha-2
+
+  Objective-C
+    Objective-C includes a code generator and a native objective-c runtime
+    library.  By adding “--objc_out” to protoc, the code generator will generate
+    a header(*.pbobjc.h) and an implementation file(*.pbobjc.m) for each proto
+    file.
+
+    In this first release, the generated interface provides: enums, messages,
+    field support(single, repeated, map, oneof), proto2 and proto3 syntax
+    support, parsing and serialization. It’s  compatible with ARC and non-ARC
+    usage. Besides, user can also access it via the swift bridging header.
+
+    See objectivec/README.md for details.
+
+  C#
+    * C# protobufs are based on project
+      https://github.com/jskeet/protobuf-csharp-port. The original project was
+      frozen and all the new development will happen here.
+    * Codegen plugin for C# was completely rewritten to C++ and is now an
+      intergral part of protoc.
+    * Some refactorings and cleanup has been applied to the C# runtime library.
+    * Only proto2 is supported in C# at the moment, proto3 support is in
+      progress and will likely bring significant breaking changes to the API.
+
+    See csharp/README.md for details.
+
+  C++
+    * Added runtime support for Any type. To use Any in your proto file, first
+      import the definition of Any:
+
+        // foo.proto
+        import "google/protobuf/any.proto";
+        message Foo {
+          google.protobuf.Any any_field = 1;
+        }
+        message Bar {
+          int32 value = 1;
+        }
+
+      Then in C++ you can access the Any field using PackFrom()/UnpackTo()
+      methods:
+
+        Foo foo;
+        Bar bar = ...;
+        foo.mutable_any_field()->PackFrom(bar);
+        ...
+        if (foo.any_field().IsType<Bar>()) {
+          foo.any_field().UnpackTo(&bar);
+          ...
+        }
+    * In text format, entries of a map field will be sorted by key.
+
+  Java
+    * Continued optimizations on the lite runtime to improve performance for
+      Android.
+
+  Python
+    * Added map support.
+      - maps now have a dict-like interface (msg.map_field[key] = value)
+      - existing code that modifies maps via the repeated field interface
+        will need to be updated.
+
+  Ruby
+    * Improvements to RepeatedField's emulation of the Ruby Array API.
+    * Various speedups and internal cleanups.
+

+This directory contains cmake files that can be used to generate MSVC project
+files in order to build protobuf on windows. You need to have cmake installed
+on your computer before proceeding.
+
+Compiling and Installing
+========================
+
+1. Check whether a gtest directory exists in the upper level directory. If
+   you checkout the code from github via "git clone", this gtest directory
+   won't exist and you won't be able to build the tests described below. To
+   avoid this problem consider downloading one of the release tar balls which
+   contains gtest already and copying the gest directory from there to your
+   protobuf directory:
+
+        https://github.com/google/protobuf/releases
+
+2. Use cmake to generate MSVC project files. Running the following commands
+   in a command shell will generate project files for Visual Studio 2008 in
+   a sub-directory named "build".
+
+        $ cd path/to/protobuf/cmake
+        $ mkdir build
+        $ cd build
+        $ cmake -G "Visual Studio 9 2008" ..
+
+3. Open the generated protobuf.sln file in Microsoft Visual Studio.
+4. Choose "Debug" or "Release" configuration as desired.
+5. From the Build menu, choose "Build Solution".  Wait for compiling to finish.
+6. From a command shell, run tests.exe and lite-test.exe and check that all
+   tests pass. Make sure you have changed the working directory to the output
+   directory because tests.exe will try to find and run test_plugin.exe
+   in the working directory.
+7. Run extract_includes.bat to copy all the public headers into a separate
+   "include" directory (under the top-level package directory).
+8. Copy the contents of the include directory to wherever you want to put
+   headers.
+9. Copy protoc.exe wherever you put build tools (probably somewhere in your
+   PATH).
+10. Copy libprotobuf.lib, libprotobuf-lite.lib, and libprotoc.lib wherever you
+   put libraries.
+
+  To avoid conflicts between the MSVC debug and release runtime libraries, when
+  compiling a debug build of your application, you may need to link against a
+  debug build of libprotobuf.lib.  Similarly, release builds should link against
+  release libs.
+
+DLLs vs. static linking
+=======================
+
+Static linking is now the default for the Protocol Buffer libraries.  Due to
+issues with Win32's use of a separate heap for each DLL, as well as binary
+compatibility issues between different versions of MSVC's STL library, it is
+recommended that you use static linkage only.  However, it is possible to
+build libprotobuf and libprotoc as DLLs if you really want.  To do this,
+do the following:
+
+  1. Add an additional flag "-DBUILD_SHARED_LIBS=ON" when invoking cmake:
+
+        $ cmake -G "Visual Studio 9 2008" -DBUILD_SHARED_LIBS=ON ..
+
+  2. Follow the same steps as described in the above section.
+  3. When compiling your project, make sure to #define PROTOBUF_USE_DLLS.
+
+When distributing your software to end users, we strongly recommend that you
+do NOT install libprotobuf.dll or libprotoc.dll to any shared location.
+Instead, keep these libraries next to your binaries, in your application's
+own install directory.  C++ makes it very difficult to maintain binary
+compatibility between releases, so it is likely that future versions of these
+libraries will *not* be usable as drop-in replacements.
+
+If your project is itself a DLL intended for use by third-party software, we
+recommend that you do NOT expose protocol buffer objects in your library's
+public interface, and that you statically link protocol buffers into your
+library.
+
+ZLib support
+============
+
+If you want to include GzipInputStream and GzipOutputStream
+(google/protobuf/io/gzip_stream.h) in libprotobuf, you will need to do a few
+additional steps:
+
+1. Obtain a copy of the zlib library.  The pre-compiled DLL at zlib.net works.
+2. Make sure zlib's two headers are in your include path and that the .lib file
+   is in your library path.  You could place all three files directly into this
+   cmake directory to compile libprotobuf, but they need to be visible to
+   your own project as well, so you should probably just put them into the
+   VC shared icnlude and library directories.
+3. Add flag "-DZLIB=ON" when invoking cmake:
+
+        $ cmake -G "Visual Studio 9 2008" -DZLIB=ON ..
+
+   If it reports NOTFOUND for zlib_include or zlib_lib, you might haven't put
+   the headers or the .lib file in the right directory.
+4) Open the generated protobuf.sln file and build as usual.
+
+Notes on Compiler Warnings
+==========================
+
+The following warnings have been disabled while building the protobuf libraries
+and compiler.  You may have to disable some of them in your own project as
+well, or live with them.
+
+* C4018 - 'expression' : signed/unsigned mismatch
+* C4146 - unary minus operator applied to unsigned type, result still unsigned
+* C4244 - Conversion from 'type1' to 'type2', possible loss of data.
+* C4251 - 'identifier' : class 'type' needs to have dll-interface to be used by
+  clients of class 'type2'
+* C4267 - Conversion from 'size_t' to 'type', possible loss of data.
+* C4305 - 'identifier' : truncation from 'type1' to 'type2'
+* C4355 - 'this' : used in base member initializer list
+* C4800 - 'type' : forcing value to bool 'true' or 'false' (performance warning)
+* C4996 - 'function': was declared deprecated
+
+C4251 is of particular note, if you are compiling the Protocol Buffer library
+as a DLL (see previous section).  The protocol buffer library uses templates in
+its public interfaces.  MSVC does not provide any reasonable way to export
+template classes from a DLL.  However, in practice, it appears that exporting
+templates is not necessary anyway.  Since the complete definition of any
+template is available in the header files, anyone importing the DLL will just
+end up compiling instances of the templates into their own binary.  The
+Protocol Buffer implementation does not rely on static template members being
+unique, so there should be no problem with this, but MSVC prints warning
+nevertheless.  So, we disable it.  Unfortunately, this warning will also be
+produced when compiling code which merely uses protocol buffers, meaning you
+may have to disable it in your code too.

+===============================================================================
+Welcome to the C# port of Google Protocol Buffers, written by Jon Skeet
+(skeet@pobox.com) based on the work of many talented people.
+
+===============================================================================
+RELEASE NOTES - Code imported into Google's main protobuf repository
+===============================================================================
+
+Everything below note this represents history of protobuf-csharp-port project
+before the code was merged into csharp/ subtree of GitHub google/protobuf
+repository.
+Frozen legacy version of the original project is available in
+https://github.com/jskeet/protobuf-csharp-port.
+
+===============================================================================
+RELEASE NOTES - Version 2.4.1.555
+===============================================================================
+
+Changes:
+- Upgrade solution format to Visual Studio 2012.
+- Add the ability to print a builder (not just a message)
+- TextGenerator introduces a new overload of PrintTo
+- Munge protoc's error format into a VS-C#-compatible output format.
+- Work to make ProtoGen clone that acts as a protoc.exe plugin.
+- Added the AllowPartiallyTrustedCallers attribute
+- Optimized enum parsing.
+
+Fixes:
+- Fix for bug in limited input stream's Position, Introduced Position on 
+  output stream
+- Fix for writing a character to a JSON output overflows allocated buffer
+- Optimize FromBase64String to return Empty when presented with empty string.
+- Use string.Concat instead of operator to avoid potential import problems
+- Issue 81: quoting for NUnit parameters.
+- Issue 56: NuGet package is noisy
+- Issue 70: Portable library project has some invalid Nunit-based code.
+- Issue 71: CodedInputStream.ReadBytes go to slow path unnecessarily
+- Issue 84: warning CS0219: The variable `size' is assigned but never used
+
+===============================================================================
+RELEASE NOTES - Version 2.4.1.521
+===============================================================================
+
+Changes:
+- Add generated_code_attributes option, defaulted to false
+- Added support for Portable library
+- Added 'Unsafe' static type in ByteString to allow direct buffer access
+
+Fixes:
+- Issue 50: The XML serializer will fail to deserialize a message with empty 
+  child message
+- Issue 45: Use of 'item' as a field name causes AmbiguousMatchException
+- Issue 49: Generated nested static Types class should be partial
+- Issue 38: Disable CLSCompliant warnings (3021)
+- Issue 40: proto_path does not work for command-line file names
+- Issue 54: should retire all bytes in buffer (bufferSize)
+- Issue 43: Fix to correct identical 'umbrella_classname' options from trying 
+  to write to the same filename.
+
+===============================================================================
+RELEASE NOTES - Version 2.4.1.473
+===============================================================================
+

+
+This directory contains the C# Protocol Buffers runtime library.
+
+Usage
+=====
+
+The easiest way to use C# protocol buffers in your project is to use the [Google.ProtocolBuffers NuGet package](http://www.nuget.org/packages/Google.ProtocolBuffers/). This package is the legacy package for C# protocol buffers, but it will work fine with C# code generated by `protoc` if you use proto2 syntax (The API of the runtime library haven't changed so far).
+
+*WARNING: If you specify `syntax = "proto3";` in your .proto files, the generated code won't necessarily work with the legacy NuGet package. So before we officially add proto3 support, always use `syntax = "proto2";` (the default) in your protos.*
+
+We will definitely release a new NuGet package for the runtime library in the future. The new runtime library WILL contain significant semantic, backwardly-incompatible changes in proto handling (mostly because we will be adding proto3 support and we will be using that oportunity to make some design changes). So keep in mind that you will need to regenerate your proto files and switch to a new NuGet package once the new version of runtime library becomes available.
+
+Building
+========
+
+Open the `src/ProtocolBuffers.sln` solution in Visual Studio. Click "Build solution" to build the solution. You should be able to run the NUnit test from Test Explorer (you might need to install NUnit Visual Studio add-in).
+
+Supported Visual Studio versions are VS2013 (update 4) and VS2015. On Linux, you can also use Monodevelop 5.9 (older versions might work fine).
+
+Proto2 & Proto3
+===============
+
+*WARNING: Only proto2 is supported for now, proto3 is under construction.*
+
+C# protocol buffers are currently under development and you should expect semantic, backward-incompatible changes in the future.
+
+Also, as of now, only proto2 is supported. Proto3 support for C# is currently in progress
+(both design & implementation) and you should not expect any of the proto3 features to work. 
+In fact, always use `syntax = "proto2";` in your .proto files for now, unless you are feeling like experimenting.
+
+History of C# protobufs
+=======================
+
+This subtree was originally imported from https://github.com/jskeet/protobuf-csharp-port
+and represents the latest development version of C# protobufs, that will now be developed
+and maintained by Google. All the development will be done in open, under this repository
+(https://github.com/google/protobuf).

+Protocol Buffers is a binary serialization format and technology, released to the open source community by Google in 2008.  
+Its primary use is to produce small fast binary representations of a 'message' or object for serialization or transportation.
+There are various implementations of Protocol Buffers in .NET. This project is a fairly close port of the Google Java implementation.
+
+There are two main parts:
+
+tools/protoc.exe, which takes the textual representation of the protocol buffer and turns it into a binary representation for use with ProtoGen.exe.
+tools/ProtoGen.exe, which takes binary representations of protocol buffer descriptors (as generated by the "stock" protoc binary supplied by Google) and creates C# source code. This is only required at build time.
+

+#
+# Script for uploading files to a Google Code project.
+#
+# This is intended to be both a useful script for people who want to
+# streamline project uploads and a reference implementation for
+# uploading files to Google Code projects.
+#
+# To upload a file to Google Code, you need to provide a path to the
+# file on your local machine, a small summary of what the file is, a
+# project name, and a valid account that is a member or owner of that
+# project.  You can optionally provide a list of labels that apply to
+# the file.  The file will be uploaded under the same name that it has
+# in your local filesystem (that is, the "basename" or last path
+# component).  Run the script with '--help' to get the exact syntax
+# and available options.
+#
+# Note that the upload script requests that you enter your
+# googlecode.com password.  This is NOT your Gmail account password!
+# This is the password you use on googlecode.com for committing to
+# Subversion and uploading files.  You can find your password by going
+# to http://code.google.com/hosting/settings when logged in with your
+# Gmail account. If you have already committed to your project's
+# Subversion repository, the script will automatically retrieve your
+# credentials from there (unless disabled, see the output of '--help'
+# for details).
+#
+# If you are looking at this script as a reference for implementing
+# your own Google Code file uploader, then you should take a look at
+# the upload() function, which is the meat of the uploader.  You
+# basically need to build a multipart/form-data POST request with the
+# right fields and send it to https://PROJECT.googlecode.com/files .
+# Authenticate the request using HTTP Basic authentication, as is
+# shown below.

+Protocol Buffers - Google's data interchange format
+===================================================
+
+[![Build Status](https://travis-ci.org/google/protobuf.svg?branch=master)](https://travis-ci.org/google/protobuf)
+
+Copyright 2008 Google Inc.
+
+This directory contains the Objective C Protocol Buffers runtime library.
+
+Requirements
+------------
+
+The Objective C implemention requires:
+
+- Objective C 2.0 Runtime (32bit & 64bit iOS, 64bit OS X).
+- Xcode 6.3 (or later).
+- The library code does *not* use ARC (for performance reasons), but it all can
+  be called from ARC code.
+
+Installation
+------------
+
+The full distribution pulled from github includes the sources for both the
+compiler (protoc) and the runtime (this directory).  To build the compiler
+and run the runtime tests, you can use:
+
+     $ objectivec/DevTools/full_mac_build.sh
+
+This will generate the `src/protoc` binary.
+
+Usage
+-----
+
+There are two ways to include the Runtime sources in your project:
+
+Add `objectivec/\*.h` & `objectivec/GPBProtocolBuffers.m` to your project.
+
+*or*
+
+Add `objectivec/\*.h` & `objectivec/\*.m` except for
+`objectivec/GPBProtocolBuffers.m` to your project.
+
+
+If the target is using ARC, remember to turn off ARC (`-fno-objc-arc`) for the
+`.m` files.
+
+The files generated by `protoc` for the `*.proto` files (`\*.pbobjc.h' and
+`\*.pbobjc.m`) are then also added to the target.
+
+The Objective C classes/enums can be used from Swift code.
+
+Objective C Generator Options
+-----------------------------
+
+**objc_class_prefix=\<prefix\>** (no default)
+
+Since Objective C uses a global namespace for all of its classes, there can
+be collisions.  This option provides a prefix that will be added to the Enums
+and Objects (for messages) generated from the proto.  Convention is to base
+the prefix on the package the proto is in.
+
+Contributing
+------------
+
+Please make updates to the tests along with changes. If just changing the
+runtime, the Xcode projects can be used to build and run tests.  If change also
+require changes to the generated code, `objectivec/DevTools/full_mac_build.sh`
+can be used to easily rebuild and test changes. Passing `-h` to the script will
+show the addition options that could be useful.
+
+Documentation
+-------------
+
+The complete documentation for Protocol Buffers is available via the
+web at:
+
+    https://developers.google.com/protocol-buffers/

+// The JSON representation of an `Any` value uses the regular

+// If the embedded message type is well-known and has a custom JSON

+// * If no schema is provided, `https` is assumed.
+// * The last segment of the URL's path must represent the fully

+//   lookup. Therefore, binary compatibility needs to be preserved
+//   on changes to types. (Use versioned type names to manage
+//   breaking changes.)
+//
+// Schemas other than `http`, `https` (or the empty schema) might be
+// used with implementation specific semantics.
+//
+// Types originating from the `google.*` package

+// `FieldMask` represents a set of symbolic field paths, for example:
+//
+//     paths: "f.a"
+//     paths: "f.b.d"
+//
+// Here `f` represents a field in some root message, `a` and `b`
+// fields in the message found in `f`, and `d` a field found in the
+// message in `f.b`.
+//
+// Field masks are used to specify a subset of fields that should be
+// returned by a get operation or modified by an update operation.
+// Field masks also have a custom JSON encoding (see below).
+//
+// # Field Masks in Projections
+// When used in the context of a projection, a response message or
+// sub-message is filtered by the API to only contain those fields as
+// specified in the mask. For example, if the mask in the previous
+// example is applied to a response message as follows:
+//
+//     f {
+//       a : 22
+//       b {
+//         d : 1
+//         x : 2
+//       }
+//       y : 13
+//     }
+//     z: 8
+//
+// The result will not contain specific values for fields x,y and z
+// (there value will be set to the default, and omitted in proto text
+// output):
+//
+//
+//     f {
+//       a : 22
+//       b {
+//         d : 1
+//       }
+//     }
+//
+// A repeated field is not allowed except at the last position of a
+// field mask.
+//
+// If a FieldMask object is not present in a get operation, the
+// operation applies to all fields (as if a FieldMask of all fields
+// had been specified).
+//
+// Note that a field mask does not necessarily applies to the
+// top-level response message. In case of a REST get operation, the
+// field mask applies directly to the response, but in case of a REST
+// list operation, the mask instead applies to each individual message
+// in the returned resource list. In case of a REST custom method,
+// other definitions may be used. Where the mask applies will be
+// clearly documented together with its declaration in the API.  In
+// any case, the effect on the returned resource/resources is required
+// behavior for APIs.
+//
+// # Field Masks in Update Operations
+// A field mask in update operations specifies which fields of the
+// targeted resource are going to be updated. The API is required
+// to only change the values of the fields as specified in the mask
+// and leave the others untouched. If a resource is passed in to
+// describe the updated values, the API ignores the values of all
+// fields not covered by the mask.
+//
+// In order to reset a field's value to the default, the field must
+// be in the mask and set to the default value in the provided resource.
+// Hence, in order to reset all fields of a resource, provide a default
+// instance of the resource and set all fields in the mask, or do
+// not provide a mask as described below.
+//
+// If a field mask is not present on update, the operation applies to
+// all fields (as if a field mask of all fields has been specified).
+// Note that in the presence of schema evolution, this may mean that
+// fields the client does not know and has therefore not filled into
+// the request will be reset to their default. If this is unwanted
+// behavior, a specific service may require a client to always specify
+// a field mask, producing an error if not.
+//
+// As with get operations, the location of the resource which
+// describes the updated values in the request message depends on the
+// operation kind. In any case, the effect of the field mask is
+// required to be honored by the API.
+//
+// ## Considerations for HTTP REST
+// The HTTP kind of an update operation which uses a field mask must
+// be set to PATCH instead of PUT in order to satisfy HTTP semantics
+// (PUT must only be used for full updates).
+//
+// # JSON Encoding of Field Masks
+// In JSON, a field mask is encoded as a single string where paths are
+// separated by a comma. Fields name in each path are converted
+// to/from lower-camel naming conventions.
+//
+// As an example, consider the following message declarations:
+//
+//     message Profile {
+//       User user = 1;
+//       Photo photo = 2;
+//     }
+//     message User {
+//       string display_name = 1;
+//       string address = 2;
+//     }
+//
+// In proto a field mask for `Profile` may look as such:
+//
+//     mask {
+//       paths: "user.display_name"
+//       paths: "photo"
+//     }
+//
+// In JSON, the same mask is represented as below:
+//
+//     {
+//       mask: "user.displayName,photo"
+//     }

 // This is a thread-safe implementation: multiple threads may allocate from the

+//
+// An arena provides two allocation interfaces: CreateMessage<T>, which works
+// for arena-enabled proto2 message types as well as other types that satisfy
+// the appropriate protocol (described below), and Create<T>, which works for
+// any arbitrary type T. CreateMessage<T> is better when the type T supports it,
+// because this interface (i) passes the arena pointer to the created object so
+// that its sub-objects and internal allocations can use the arena too, and (ii)
+// elides the object's destructor call when possible. Create<T> does not place
+// any special requirements on the type T, and will invoke the object's
+// destructor when the arena is destroyed.
+//
+// The arena message allocation protocol, required by CreateMessage<T>, is as
+// follows:
+//
+// - The type T must have (at least) two constructors: a constructor with no
+//   arguments, called when a T is allocated on the heap; and a constructor with
+//   a google::protobuf::Arena* argument, called when a T is allocated on an arena. If the
+//   second constructor is called with a NULL arena pointer, it must be
+//   equivalent to invoking the first (no-argument) constructor.
+//
+// - The type T must have a particular type trait: a nested type
+//   |InternalArenaConstructable_|. This is usually a typedef to |void|. If no
+//   such type trait exists, then the instantiation CreateMessage<T> will fail
+//   to compile.
+//
+// - The type T *may* have the type trait |DestructorSkippable_|. If this type
+//   trait is present in the type, then its destructor will not be called if and
+//   only if it was passed a non-NULL arena pointer. If this type trait is not
+//   present on the type, then its destructor is always called when the
+//   containing arena is destroyed.
+//
+// - One- and two-user-argument forms of CreateMessage<T>() also exist that
+//   forward these constructor arguments to T's constructor: for example,
+//   CreateMessage<T>(Arena*, arg1, arg2) forwards to a constructor T(Arena*,
+//   arg1, arg2).
+//
+// This protocol is implemented by all arena-enabled proto2 message classes as
+// well as RepeatedPtrField.

+//  2. There's a performance hit to converting between bytes and strings and
+//     it many cases, the field is never even read by the application code. This
+//     avoids unnecessary conversions in the common use cases.
+//
+// So now, the field for String is maintained as an Object reference which can
+// either store a String or a ByteString. The code uses an instanceof check
+// to see which one it has and converts to the other one if needed. It remembers
+// the last value requested (in a thread safe manner) as this is most likely
+// the one needed next. The thread safety is such that if two threads both
+// convert the field because the changes made by each thread were not visible to
+// the other, they may cause a conversion to happen more times than would
+// otherwise be necessary. This was deemed better than adding synchronization
+// overhead. It will not cause any corruption issues or affect the behavior of
+// the API. The instanceof check is also highly optimized in the JVM and we
+// decided it was better to reduce the memory overhead by not having two
+// separate fields but rather use dynamic type checking.
+//
+// For single fields, the logic for this is done inside the generated code. For
+// repeated fields, the logic is done in LazyStringArrayList and
+// UnmodifiableLazyStringList.
