• Java version: 11.0.1
• gbc & compiler library: 0.13.0.0

gbc and Bond compiler library

• Breaking change: Codegen for Bond-over-gRPC has been removed: the
  --grpc switch is no longer supported. Service definitions are still
  parsed, but codegen can no longer be done for C++ or C#. See issue
  #1131, Bond-over-gRPC will be deprecated February
  2022, for the full
  announcement.

C++

• Breaking change: All Bond-over-gRPC code has been removed. This is
  everything under the bond::ext:grpc namespace. Service definitions can
  still appear in .bond files, but no C++ code will be generated for them.
  See issue #1131, Bond-over-gRPC will be deprecated February
  2022, for the full
  announcement.
• By default, deserialization will no longer process very deeply nested
  structures. Instead, an bond::CoreException will be thrown in order to
  protect against stack overflows. The depth limit may be changed by calling
  the function bond::SetDeserializeMaxDepth(uint32_t).
• Fixed handling of large containers of invalid types that could cause
  excessive CPU use when deserializing some payloads.

C#

• Breaking change: Update of Newtonsoft.Json library to version 13.3.0.
  (Issue #1156)

  This update fixes depth check in input JSON string (by default: 64).
  Depth check is necessary to prevent stack overflow issue with long payloads.

• Breaking change: The minimum supported version of .NET Framework is
  4.6.2. Support for .NET Framework 4.5 has been dropped.

• Breaking change: All Bond-over-gRPC code has been removed. This is
  everything under the Bond.Grpc namespace and the Bond.Grpc.CSharp NuGet
  package. Service definitions can still appear in .bond files, but no C#
  code will be generated for them. See issue #1131, Bond-over-gRPC will be
  deprecated February 2022,
  for the full announcement.

• Added codegen and deserialization support for container type aliases to
  use
  System.Collections.Immutable
  collections. (Pull request
  #1161)

• By default, deserialization will no longer process very deeply nested
  structures. Instead, an InvalidOperationException will be thrown in
  order to protect against stack overflows. The depth limit may be changed
  by setting the property Bond.DeserializerControls.Active.MaxDepth.

Java

• By default, deserialization will no longer process very deeply nested
  structures. Instead, a org.bondlib.InvalidBondDataException exception
  will be thrown in order to protect against stack overflows. The depth
  limit may be changed by calling the method
  org.bondlib.bond.DeserializerControls.setMaxDepth.

10.0: 2022-03-07

• IDL core version: 3.0
• C++ version: 10.0
• C# NuGet version: 10.0
• gbc & compiler library: 0.12.1.0

C++

• Breaking change: Bond-over-gRPC has been marked deprecated.
  Bond-over-gRPC will be removed in the next major version of Bond. See
  issue #1131, Bond-over-gRPC will be deprecated February
  2022, for the full
  announcement.
  • The [[deprecated]] attribute has been added to the bond::ext::grpc
    namespace in every top-level Bond-over-gRPC++ header. This will cause
    compiler warnings/errors for uses of Bond-over-gRPC++ that you may need
    to handle.
• Fixed multiple symbol definition for Win32Exception in
  grpc/win_thread_pool.h. (Issue
  #1129)
• Add forward declaration for GenericWriteVariableUnsigned to fix "C3861:
  'GenericWriteVariableUnsigned': identifier not found" when using custom
  streams that do not have their own implementation of
  WriteVariableUnsigned. (Issue
  #1115)
• Fixed bond::DynamicParser that may not emit transform's OmittedField
  for compile-time schema and an omitted optional field in the payload.
  (Issue #1120)
• Fixed missing include directives.
• Removed bond::blob's unnecessary _content member, reducing its size
  by 1 pointer.
• Added an ability to apply transform to a schema.
• Added noexcept to bond::blob's non-throwing functions.

C#

• Breaking change: Bond-over-gRPC code has been marked deprecated.
  Bond-over-gRPC will be removed in the next major version of Bond. See
  issue #1131, Bond-over-gRPC will be deprecated February
  2022, for the full
  announcement.
  • The [Obsolete] attribute has been added to every public type in the
    Bond.Grpc assembly. This will cause compiler warnings/errors for uses
    of Bond-over-gRPC# that you may need to handle.
• Added virtual method OutputBuffer.ResizeBuffer that can be overridden to
  use buffer allocators other than new byte[] (e.g.
  ArrayPool<byte>.Rent()). (Pull request
  #1128)
• The error message emitted when duplicate .bond items are detected by the
  MSBuild codegen now correctly refers to $(EnableDefaultItems) as the
  switch that controls this behavior. (Issue
  #1110)

9.0.5: 2021-04-14

• IDL core version: 3.0
• C++ version: 9.0.5
• C# NuGet version: 9.0.5
• gbc & compiler library: 0.12.1.0

C++/Python

• Added CMake variable BOND_FIND_GRPC to allow for external gRPC
  installations. The search for external GRPC installations is only done
  when BOND_ENABLE_GRPC is TRUE.
• Removed use of deprecated std::ptr_fun in the Python library. (Issue
  #1080)

C#

• Implicit codegen now excludes any .bond files in the project's output
  directories (e.g., bin/, obj/debug/netstandard1.0). This behavior
  matches the implicit compilation behavior for .cs files.

9.0.4: 2020-11-23

• IDL core version: 3.0
• C++ version: 9.0.4
• C# NuGet version: 9.0.3
• gbc & compiler library: 0.12.1.0

C++

• Bond now uses the [[noreturn]] attribute to annotate functions that do
  not return. Previously, it used compiler-specific annotations.

C#

• There were no C# changes in this release.

9.0.3: 2020-08-06

• IDL core version: 3.0
• C++ version: 9.0.2
• C# NuGet version: 9.0.3
• gbc & compiler library: 0.12.1.0

C++

• There were no C++ changes in this release.

C#

• Fixed a performance regression in OutputBuffer.Grow: it was incorrectly
  growing the buffer by one byte at a time instead of geometrically. (Issue
  #1065, Pull request
  #1066)

9.0.2: 2020-08-03

• IDL core version: 3.0
• C++ version: 9.0.2
• C# NuGet version: 9.0.2
• gbc & compiler library: 0.12.1.0

C++

• gbc is now installed with 555 (r-xr-xr-x) permissions. (Issue
  #1062)

C#

• Fixed a regression writing to non-seekable streams using
  CompactBinaryWriter. The fix in commit
  b0fd4a1
  inadvertently added a call to Stream.Position in the Release
  configuration. This call is only indented to be made when Bond is built in
  the Debug configuration.

9.0.1: 2020-07-14

• IDL core version: 3.0
• C++ version: 9.0.1
• C# NuGet version: 9.0.1
• gbc & compiler library: 0.12.1.0

C++

  • The RapidJSON submodule now uses its new home under the Tencent
    organization.

C#

• Fixed MSB3105/CS2002 error about duplicate Compile items when a directory
  contains multiple .bond files and --gprc is in $BondOptions. (Issue
  #1050)
• Fix handling of large container lengths that could cause an infinite loop
  when deserializing some payloads. This fix addresses
  CVE-2020-1469.

• IDL core version: 3.0
• C++ version: 9.0.0
• C# NuGet version: 9.0.0
• gbc & compiler library: 0.12.1.0

C++

• Breaking change MSVC 2013 support has been removed. (Issue
  #851)
• Breaking change bond/core/warning.h has been deleted. Since the
  5.3.0 release, Bond hasn't needed global warning
  suppressions for any compiler except MSVC 2013. This file was only used
  for MSVC 2013, which is no longer a supported compiler.
• Fixed MSVC warning for deprecation of std::result_of_t in /std:c++17.
  (Issue #1007)
• Fixed MSVC warning C5208: unnamed class used in typedef name cannot
  declare members other than non-static data members, member enumerations,
  or member classes. (Issue
  #1027)
• Fixed Boost 1.73 warning "The practice of declaring the Bind placeholders
  (_1, _2, ...) in the global namespace is deprecated." (Pull request
  #1036)

C#

• Fixed creation of duplicate default constructor when defining an empty struct
  and using --preview-constructor-parameters.
  (Issue #963)
• The .NET assemblies are now only Authenticode signed with SHA-2. Legacy
  Windows OS versions may need updates to work with SHA-2
  signatures.

gbc and Bond compiler library

• C++ codegen no longer supports MSVC 2013.
• gbc is now only Authenticode signed with SHA-2. Legacy Windows OS versions
  may need updates to work with SHA-2
  signatures.

8.2.0: 2019-11-18

• IDL core version: 3.0
• C++ version: 8.2.0
• C# NuGet version: 8.2.0
• gbc & compiler library: 0.12.0.0

C++

• gRPC v1.17.1 is now required to use Bond-over-gRPC.
• Fixed an ambigious HexDigit overload compilation error when
  compiling with some versions of GCC. (Pull request
  #954)
• Fixed ambiguous call to maybe::operator== that breaks GCC 9
  build. (Pull request
  #975)
• Fixed MSVC warning C4296: "'<': expression is always false" in protocol.h.
  (Issue
  #981)

C#

• Added .NET 4.6 target framework to Bond.IO.dll so that it can use
  MemoryStream.TryGetBuffer() when cloning streams like is done when
  targeting .NET Standard 1.3+.

Bond compiler library

• Breaking change The bond compiler library (the Haskell library) and
  gbc have been switched to build with stackage snapshot lts-14.4. This
  snapshot uses megaparsec 7 and aeson 1.4.4, both of which had breaking
  changes that are reflected in the library, e.g., the parseBond signature
  has changed. There is no impact to users of the gbc command line tool or
  changes to C++ and C# code generation.

8.1.0: 2019-03-27

C++

• C# / Nuget release only

C#

• Updated to gRPC v1.17.1.
• Add a constructor that accepts a CallInvoker instance to the generated
  gRPC clients to support client-side interceptors. For more details about
  C# interceptors, see the proposal in the gRPC
  project.
  Issue #950

8.0.1: 2018-06-29

• gbc & compiler library: 0.11.0.3
• IDL core version: 3.0
• C++ version: 8.0.1
• C# NuGet version: 8.0

C++

• Fixed a crash in bond::ext::grpc::server's destructor when invoked on
  a moved-from object instance.
• Added move-assignment operator to bond::blob.
• Added cmake variable BOND_FIND_RAPIDJSON to allow for external RapidJSON installations.

C#

• There were no C# changes in this release.

• gbc & compiler library: 0.11.0.0
• IDL core version: 3.0
• C++ version: 8.0
• C# NuGet version: 8.0

gbc and Bond compiler library

• Breaking change The deprecated Bond Comm functionality has been removed.
  This includes all gbc options related to Comm and the Comm codegen templates
  in the Haskell library. Issue
  #824
• C++ codegen now properly generates move assignment operators. Previously,
  this was broken for some cases.
• C++ codegen no longer generates checks for C++11, except for MSVC 2013
  workarounds.
• C++ codegen no longer generates data member initialization that invokes a
  constructor accepting Comparer for associative containers.
• C++ codegen can now generate copy and move constructors with an allocator
  argument when a custom allocator is used and --alloc-ctors is passed to
  gbc.
• C++ codegen can now generate type
  aliases that
  correspond to ones in IDL when the --type-aliases flag is passed to gbc.
• C++ codegen can now use
  std::scoped_allocator_adaptor
  for strings and containers when a custom allocator is used and the
  --scoped-alloc flag is passed to gbc.
• C++ codegen now generates lazily constructed enum name-to-value and
  value-to-name maps. Additionally, a user-defined map type can now be
  provided to GetNameToValueMap and GetValueToNameMap.
• C++ codegen now applies the --export-attribute to the ToString,
  FromString, ToEnum and FromEnum functions.
• Fixed a bug in C++ codegen that incorrectly applied the export attribute to
  generic gRPC services.
• C++ codegen now generates an allocator_type typedef for a struct when the
  --allocator option is passed to gbc, instead of specializing
  std::uses_allocator.
• import statements can now end with an optional semicolon.
• File and directory paths on the command line, in response files, or in
  import statements can now use a mix of forward and backslashes. Issue
  #869
• gbc is now Authenticode dual-signed with both SHA1 and SHA2.

C++

• Breaking change The deprecated Bond Comm functionality has been removed.
  This includes all gbc options related to Comm and all Comm APIs and header
  files. Issue #824
• Breaking change Only versions of Boost released in the past two years
  (1.61 and newer) are supported. Bond will likely continue to work with
  older versions, but it is no longer tested with anything older than 1.61.
  Test coverage for Boost versions 1.61–1.66 has been improved. Issue
  #771
• Breaking change Constructors accepting a Comparer have been removed
  from the bond::maybe and bond::nullable types.
• Breaking change The bond::is_blob and bond::is_nullable traits have
  been removed. The blob and nullable types are not customizable, so these
  where never needed or used. The related functionality provided by
  bond::get_list_sub_type_id remains.
• Breaking change Removed a dangerous implicit conversion operator from
  bond::maybe<T> to const T&. To access a bond::maybe<T> value, use one
  of the bond::maybe<T>::value functions.
• Breaking change The nested pointer, const_pointer, reference and
  const_reference typedefs have been removed from bond::nullable<T>.
• Breaking change The Allocator (second) type parameter has be removed
  from bond::nullable<T> and now it is always deduced from T.
• Breaking change The bond::capped_allocator and related types have been
  moved to the bond::ext namespace and the "bond/ext" include directory.
• Breaking changes in Bond-over-gRPC (based on real-world use and
  feedback). Check the updated
  examples
  to see how to use the changed APIs.
  • The generated ClientCore and ServiceCore class templates and the
    Client and Service convenience typedefs have all been replaced with
    normal classes named Client and Service. The ThreadPool type
    parameter has been removed in favor of a simplified runtime representation
    of a Scheduler.
  • The Scheduler concept and the bond::ext::gRPC::thread_pool
    implementation now use operator() instead of a schedule() member
    function.
  • The bond::ext::gRPC::server_core class template and the
    bond::ext::gRPC::server convenience typedef have been replaced with the
    normal class bond::ext::gRPC::server.
  • The generated Client::Async* functions now accept the
    std::shared_ptr<grpc::ClientContext> argument as the last parameter
    instead of as the first. This makes is easier to omit this parameter when
    no context customization is needed.
  • The client callback now directly accepts
    bond::ext::gRPC::unary_call_result<Response> (drops the
    std::shared_ptr). Also the unary_call_result now exposes read-only
    getters rather than fields. This simplified the type that clients need to
    deal with.
  • The bond::ext::gRPC::wait_callback::arg_type has been removed.
  • The client_callback.h header file has been renamed to
    unary_call_result.h to align with its contents.
  • The bond::ext::gRPC::server_builder has been replaced by the
    bond::ext::gRPC::server::Start factory function which now returns a
    plain bond::ext::gRPC::server object and accepts service instances
    managed by std::unique_ptr. This properly models the lifetime
    requirements. Service implementations must now pass a Scheduler to the
    generated Service base class which is no longer default constructible.
  • The generated method reflection information no longer uses a redundant
    bonded<T> wrapper for input_type and result_type typedefs.
  • The bond::ext::gRPC::unary_call no longer requires bonded<T> wrapper
    for request type.
  • The bond::ext::gRPC::unary_call::FinishWithError has been renamed to
    Finish. Overloads that take a status can be used to signal an error.
  • The grpc::Status second argument has been removed from
    bond::ext::gRPC::unary_call::Finish. gRPC does not support sending a
    response with a non-OK status, so the payload was being droped anyway.
  • Fixed bond::ext::gRPC::unary_call, bond::ext::gRPC::shared_unary_call
    and bond::ext::gRPC::unary_call_result types to properly use void and
    bond::reflection::nothing instead of the bond::Void empty struct. Also
    removed unnecessary functions from unary_call and shared_unary_call
    for those cases when they are not applicable (e.g. Finish is not
    available when return type is nothing).
• gRPC v1.12.0 is now required to use Bond-over-gRPC.
  • This version include a number of memory leak fixes that users of
    Bond-over-gRPC were encountering. Issue
    #810
  • This version include some Windows-specific performance
    improvements for loopback connections.
• The bond::ext::gRPC::wait_callback has been deprecated in favor of
  additionally generated client functions that return std::future.
• Fixed includes for gRPC services with events or parameterless methods.
  Issue #735
• Fixed a bug which would read an unrelated struct's field(s) when
  deserializing a base struct. Issue
  #742
• Fixed a bug in bond::MapTo<T>::Field that failed to pass the Protocols
  type parameter to bond::Apply.
• Fixed a race condition when bond::ext::gRPC::io_manager::shutdown and
  bond::ext::gRPC::io_manager::wait are called concurrently.
• Fixed a race condition during bond::ext::gRPC::unary_call destruction.
• Fixed the broken move constructor of bond::bonded<T, Reader&>.
• Fixed the move constructor of bond::value to actually move the underlying reader.
• Added the bond::blob_prolong helper function that will return a
  bond::blob with a copied data if the original one does not own the memory.
• The bond::OutputBuffer::GetBuffers now can accept arbitrary STL-like
  containers.
• bond::maybe<T> has been overhauled.
  • Fixed a bug that default initialized an instance of T even when a
    maybe held nothing.
  • Added noexcept variants of bond::maybe<T>::value.
  • Added bond::maybe<T>::emplace to construct a maybe's value in place.
  • Added various rvalue-reference and allocator-aware constructors and
    assignment operators.
  • Added operator==(const bond::maybe<T>&, const T&) and
    operator==(const T&, const bond::maybe<T>&) to compare directly to
    instances of T.
• Fixed an issue with the ToString, FromString, ToEnum and FromEnum
  functions that were previously not exported from a DLL when the
  --export-attribute option was passed to gbc. Issue
  #861
• Fixed a bug in bond::nullable<T, Alloc> where it was not propagating an
  allocator to T when allocator_type was not explicitly defined.
• Fixed a bug in bond::make_box where const T& was not handled correctly.
• The use of bond::check_method has been replaced with less restricting
  expression SFINAE checks on supported compilers. Issue
  #896
• Fixed a bug where bond::ext::gRPC::io_manager could cause a thread to join
  itself.
• The preferred namespace for Bond-over-gRPC is now bond::ext::grpc. The
  previous namespace, bond::ext::gRPC, continues to work.
• Added a Windows-specific implementation of a thread
  pool.

C#

• Breaking change The deprecated Bond Comm functionality has been removed.
  This includes all gbc options related to Comm and all Comm APIs, assemblies,
  and NuGet packages. Issue
  #824
• Breaking change The Bond.CSharp and Bond.Compiler.CSharp NuGet packages
  perform implicit codegen when the simplified .NET Core .csproj format is
  used. This breaking change does not affect projects using the classic
  .csproj format. Any .NET Core projects that encounter the build error
  "Duplicate BondCodegen items were included." and were explicitly listing
  BondCodegen items will either need to rely on implicit codegen or disable
  all implicit inclusion. To set per-item
  metadata, use the item update
  syntax.
  Issue #636
• The C# attribute Bond.Attribute can now be applied to methods. This fixes
  broken codegen when attributes are used on service methods. Issue
  #617
• Bond Attributes on service methods are now present on all the client
  overloads for the methods. Previously, just the "friendly" method had the
  attributes.
• Grpc.Core v1.12.0 is now required to use Bond-over-gRPC.
  • This version include a number of memory leak fixes that users of
    Bond-over-gRPC were encountering. Issue
    #810
  • This version include some Windows-specific performance improvements for
    loopback connections.
• BondCodegen items will now appear in the Visual Studio 2017+ UI in .NET
  Core projects.
• The .NET Standard assemblies are fully strong-name signed. Previously, they
  were inadvertently only public strong-name signed.
• The .NET assemblies are now Authenticode dual-signed with both SHA1 and
  SHA2.
• Fixed a bug in the codegen targets when using gbc from $PATH on macOS and
  Linux that prevented the C# compiler from finding the generated C# files.
• Preview: Added preliminary support for generating types with constructors
  with parameters for each field. This functionality will change in the future
  and may be removed. Pull request
  #857

This is a preview release of Bond codegen for Java.

  required blob field.

7.0.0: 2017-10-24

• gbc & compiler library: 0.10.1.0
• IDL core version: 2.0
• IDL comm version: 1.2
• C++ version: 7.0.0
• C# NuGet version: 7.0.0
• C# Comm NuGet version: 0.13.0

gbc and Bond compiler library

• Add service/method annotations in C# for Comm and gRPC.
• Add service/method metadata support in C++ for gRPC.
• C++ codegen now uses std::allocator_traits
  for rebinding allocator types.

C++

• Added bond::make_box helper function to create bond::Box<T> instances.
• When Unicode conversion fails during JSON deserialization to wstring, a
  bond::CoreException is now thrown instead of a Boost exception.
• When SimpleJSON deserializes a map key with no matching value, a
  bond::CoreException is now thrown.
• When SimpleJSON deserializes a map key of non-primitive type, a
  bond::CoreException is now thrown.
• Errors from some versions of G++ like "non-template type Deserialize
  used as a template" have been fixed.
  Issue #538
• Guard against overflows in OutputMemoryStream, blob, and SimpleArray.
• Use RapidJSON's iterative parser to handle deeply nested JSON data without
  causing a stack overflow.
• Guard against min/max being function-style macros in more places.
• Allow Bond-generated C++ types to use non-default-constructable
  allocators. (This works even on MSVC 2013 by only compiling the
  generated-type's default constructor if it is used. The default
  constructor is now a templated constructor that is invokable with zero
  arguments.)
• Fixed some macro uses that did not have sufficient parenthesis around
  parameters and resulted in compiler errors.
• Added the bond::ext::gRPC::shared_unary_call type. This type can be used
  when shared ownership semantics are needed for unary_call instances.
• Provide compile-time access to metadata about gRPC services and methods.
• Using bond::ext::gRPC::wait_callback no longer causes a shared_ptr cycle
  and the resulting resource leak.
• Ensure that bond_grpc.h and bond_const_grpc.h are generated when the
  CMake variable BOND_ENABLE_GRPC is set to that importing bond.bond and
  bond_const.bond when defining a service works.
• Added bond::capped_allocator adapter that will allow to limit the max
  number of bytes to allocate during deserialization.

C#

• Breaking change The code generation MSBuild targets no longer support
  Mono's xbuild: only MSBuild is supported. Mono has
  deprecated xbuild in favor of MSBuild
  now that
  MSBuild is open source and cross-platform.
• Breaking change The code generation MSBuild targets now automatically
  compile the generated _grpc.cs files if --grpc is passed to gbc.
  Explicit <Compile Include="$(IntermediateOutputPath)foo_grpc.cs" />
  lines in MSBuild projects will need to be removed to fix error MSB3105
  about duplicate items. See commit
  a120cd99
  for an example of how to fix this.
  Issue #448
• Breaking change The low-level API IParser.ContainerHandler now has an
  arraySegment parameter for the converted blob.
• The code generation MSBuild targets will now skip compiling the
  _types.cs files when --structs=false is passed to gbc.
• Added Bond.Box.Create helper method to create Bond.Box<T> instances.
• Reflection.IsBonded now recognizes custom IBonded implementations.
• Use Newtonsoft's JSON.NET BigInteger support -- when available -- to
  handle the full range of uint64 values in the SimpleJson protocol (.NET
  4.5 or greater, .NET Standard 1.6 or greater).
• Bond.IO.Unsafe.InputStream can now be used with streams that do not
  implement Stream.Seek, like
  System.IO.Compression.GzipStream.
  Issue #498
  • Such streams are detected by inspecting
    Stream.CanSeek.
• Fix a bug in CompactBinaryWriter when using v2 that repeated first pass
  when a bonded field was serailized, resulting in extra work and extra
  state left in the CompactBinaryWriter.
• Apply IDL annotations to services and methods for gRPC.
  Issue #617
• Fixed a bug that produced C# code that couldn't be compiled when using
  Bond-over-gRPC with a generic type instantiated with a collection.
  Issue #623
• When targeting .NET 4.5, avoid resolving external entities when using
  SimpleXmlReader.
• Remove redundant conversions during serialization of aliased blobs.

C# Comm

• Apply IDL annotations to services and methods for Comm.

• gbc & compiler library: 0.10.0.0
• IDL core version: 2.0
• IDL comm version: 1.2
• C++ version: TBD 6.0.0
• C# NuGet version: 6.0.0
• C# Comm NuGet version: 0.12.0

gbc and Bond compiler library

• IDL support for service inheritance syntax
  • Breaking change In the Bond Haskell library, the Service type
    has a new field serviceBase.
• C++ codegen now generates
  extern templates
  of bond::Apply instead of overloads.
• C++ codegen hides FieldTemplate details, shortening symbol names.

C++

• Breaking change A C++11 compiler is now required. The minimum
  supported C++ compiler versions are now:
  • Clang 3.4 or newer
  • GNU C++ 4.7 or newer
  • Microsoft Visual C++ 2013 or newer
• Breaking change The generated apply.h/.cpp files now contain
  extern templates
  of bond::Apply instead of overload implementations. Calls to bare Apply
  or TypeNamespace::Apply must be changed to bond::Apply.
• Breaking change Users who are implementing custom streams are now
  required to provide the free functions CreateInputBuffer,
  CreateOutputBuffer and GetBufferRange, depending on which scenarios
  are used (there will be a corresponding compilation error for each case).
  • Users who were mistakenly calling bond::Merge<T> with explicit an
    template argument will get a compilation error. To fix, remove the
    <T> part.
  • In addition, users of MSVC12 are required to define a range_type
    typedef as a return type of corresponding GetBufferRange inside
    their custom input buffer implementation.
  • Please see
    InputBuffer,
    OutputBuffer,
    and
    the bf example
    for more details.
• Breaking change The bond::customize<protocols> has been removed. All the
  public APIs that require a protocol list (e.g. bond::Marshal) now accept
  an extra template argument Protocols which defaults to bond::BuiltInProtocols.
  Custom input streams now require bond::type_id<> to be specialized with a
  unique magic number. For more details please see the bf example.
• Initial support for sending
  Bond objects over gRPC
  has been added.
• The bond::Apply function now has a uniform signature. Call sites for the
  Marshaler<Writer> transform overload that were mistakenly passing
  Writer explicitly (e.g. bond::Apply<Writer>(marshaler, value)) will
  now get a compiler error. To fix, remove the <Writer> part:
  bond::Apply(marshaler, value).
• Fixed a bug that caused serialization using
  CompactBinaryWriter<OutputCounter> (to get the expected length of
  serializing with compact binary) to produced bogus results.
• Fixed
  custom streams
  support which was broken for some scenarios.
• For Visual C++ 2017 compability, RapidJSON v1.0.0 or newer is now
  required. The RapidJSON submodule that Bond uses by default has been
  updated to v1.1.0 due to a warning from clang in earlier versions.
• C++ codegen hides FieldTemplate details, shortening symbol names.

C#

• Breaking change Support for .NET 4.0 has been dropped from the
  supported frameworks.
• Breaking change The deprecated type Bond.BondReflection has been
  removed. The type Bond.Reflection should be used instead.
• Breaking change Bond assemblies are now
  strong-name signed
  with the
  bond.snk
  key in the repository instead of with a Microsoft key. This allows anyone
  to produce compatible assemblies, not just Microsoft. Official
  distribution of Bond will continue to be
  Authenticode signed
  with a Microsoft certificate.
  Issue #414
  • The new public key for assemblies is now
    00240000048000009400000006020000002400005253413100040000010001000d504ac18b4b149d2f7b0059b482f9b6d44d39059e6a96ff0a2a52678b5cfd8567cc67254132cd2debb5b95f6a1206a15c6f8ddac137c6c3ef4995f28c359acaa683a90995c8f08df7ce0aaa8836d331a344a514c443f112f80bf2ebed40ccb32d7df63c09b0d7bef80aecdc23ec200a458d4f8bafbcdeb9bf5ba111fbbd4787
• Breaking change Bond assemblies now have assembly and file versions
  that correspond to their NuGet package version. Strong name identities
  will now change release-over-release in line with the NuGet package
  versions. Issue #325
• The codegen MSBuild targets will now re-run codegen if gbc itself has been
  changed.
• Fixed a bug where JSON and XML protocols would permit the serialization of
  non-nullable string fields that were set to null instead of throwing a
  NullReferenceException.

gbc and Bond compiler library

• C++ codegen ensures that parameter names do not shadow field names.
• When generating C++ apply files, there are now explicit bond::Apply<>
  instantiations for CompactBinaryWriter<OutputCounter> and
  SimpleBinaryWriter<Null> writers.
  Pull request #373
  • Breaking change (Haskell library only):
    Language.Bond.Codegen.Cpp.ApplyOverloads.Protocol is now a union of
    ProtocolReader and ProtocolWriter to permit mixing and matching of
    reader/writer protocols without having to explicitly compute the full
    cross product.
• Add gbc flags to pick which C# files to generate (structs, gRPC, and
  comm). Only structs are generated by default.
• gbc ensures that method names are unique within a service.
  Issue #381

C++

• Fix Python shared_ptr converter build break with Boost 1.63.
• Improve compliance with
  Microsoft's SDL.
  • Bond now builds on MSVC with
    _CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES
    instead of _CTR_SECURE_NO_WARNINGS.
  • Bond builds on MSVC with SDL recommended warnings enabled.
• Eliminate need for warning suppression on MSVC14 via warning.h in Bond
  itself. warning.h is still in place on MSVC12; furthermore, we don't alter
  warning.h for now as it may be depended upon by application code.
• Avoid unaligned memory access on non-x86/x64 platforms.
  Issue #305
• Improve compliance with strict-aliasing rules.
  • Bond now builds on Clang/GCC with -fstrict-aliasing.
• When generating C++ apply files, there are now explicit bond::Apply<>
  instantiations for CompactBinaryWriter<OutputCounter> and

  Pull request #373
• Improve C++ allocator support
  Issue #379
  Pull request #380
  • Support C++11 and above allocator model for rebind
  • Simplify detection of the default allocator
• Remove per-field instantiation of DynamicParser<>::UnknownFieldOrTypeMismatch method.

C#

• Added gRPC integration. See the
  Bond-over-gRPC manual.
• Added controls to cap incremental allocation between reads in
  Bond.IO.Unsafe.InputStream.
• Extended fix for bug parsing JSON when a string value is a date.
  Pull request #358
• Bond C# 5.1.0 accidentally broke backward compability by renaming
  Bond.Reflection to Bond.BondReflection. This has been fixed:
  Bond.BondReflection was unrenamed back to Bond.Reflection, and a shim
  Bond.BondReflection type now redirects all calls to their original names
  to minimize further breakage.
  Issue #369
  • Code that started using Bond.BondReflection by name will encounter
    warning CS0618 indicating use of an obselete method/type. To fix this,
    use the original name Bond.Reflection. This warning can be
    suppressed if needed. However...
  • ...the shim type Bond.BondReflection will be removed during or after
    the next major release of C# Bond.

C# Comm

• Breaking change To generate C# Comm files, be sure to pass the
  --comm flag to gbc.
  See how the pingpong example was updated.
• C# Comm is now deprecated. We recommend that you use Bond-over-gRPC. See
  the
  Bond-over-gRPC manual.
• EpoxyListener's StopAsync() now stops all the outstanding connections that
  it accepted.
• EpoxyTransport's StopAsync() now stops all the connections and listeners
  that it created.
