1.17.4 / 2026-03-26
-------------------

Fixed:

1.17.0 / 2024-06-02
-------------------

* Add FFI::AbstractMemory#read_array_of_string . It was defined but not exposed to Ruby nor tested. #1070


1.17.0.rc2 / 2024-04-22
-------------------

Fixed:
* Add missing write barriers to StructLayout#initialize causing a segfault with GC.stress. #1079


1.17.0.rc1 / 2024-04-08
-------------------

Fixed:
* Fix type definitions on `aarch64-linux`. #1067, #1066
* Use RB_TEST for `Pointer.autorelease=` . #1065
  So that `false` and `nil` are treated as falsey and anything else as truthy.
* Replace Fixnum by Integer. #1064
  Fixnum is no longer present in the ruby language.
* Update `FFI::NativeType` doc. #1061
* Store FFI::Type::Mapped of FFI::StrPtrConverter in global instead of custom type map
* Various documentation fixes. #1042

-------------------

Fixed:
* Fix an issue with signed bitmasks when using flags on the most significant bit. #949
* Fix FFI::Pointer#initialize using NUM2LL instead of NUM2ULL.
* Fix FFI::Type#inspect to properly display the constant name. #1002
* Use libffi closure allocations on hppa-Linux. #1017
  Previously they would segfault.
* Fix class name of Symbol#inspect.
* Fix MSVC support of libtest. #1028
* Fix attach_function of functions ending in ? or ! #971

Added:
* Convert all C-based classes to TypedData and use write barriers. #994, #995, #996, #997, #998, #999, #1000, #1001, #1003, #1004, #1005, #1006, #1007, #1008, #1009, #1010, #1011, #1012
  This results in less pressure on the garbage collector, since the objects can be promoted to the old generation, which means they only get marked on major GC.
* Implement `ObjectSpace.memsize_of()` of all C-based classes.
* Make FFI Ractor compatible. #1023
  Modules extended per `extend FFI::Library` need to be frozen in order to be used by non-main Ractors.
  This can be done by calling `freeze` below of all C interface definitions.
  * In a Ractor it's possible to:
    * load DLLs and call its functions, access its global variables
    * use builtin typedefs
    * use and modify ractor local typedefs
    * define callbacks
    * receive async callbacks from non-ruby threads
    * use frozen FFI::Library based modules with all attributes (enums, structs, typedefs, functions, callbacks)
    * invoke frozen functions and callbacks defined in the main Ractor
    * use FFI::Struct definitions from the main Ractor
  * In a Ractor it's impossible to:
    * create new FFI::Library based modules
    * create new FFI::Struct definitions
    * use custom global typedefs
    * use non-frozen FFI::Library based modules
* Allow type retrieval of attached functions+variables. #1023
* Make FFI classes `GC.compact` friendly. #1021
* Update libffi and disable custom trampoline when using libffi closure allocation. #1020
  This is because libffi changed the way how closures are allocated to static trampolines.
* Add types.conf for loongarch64-linux. #943
* Add types.conf for sw_64-linux (Shen Wei 64-bit, based on Alpha).  #1018
* Add support for aarch64-windows. #1035
* Windows: Update LoadLibrary error message to include error code. #1026
* Allow private release method for FFI::ManagedStruct and FFI::AutoPointer. #1029
* Add support for passing ABI version to FFI.map_library_name. #963
  This adds the new class FFI::LibraryPath .
* Add support for ruby-3.2 to windows binary gem. #1047
* Enable debug symbols for `rake compile` builds to ease debugging. #1048

Removed:
* Remove allocator of AbstractMemory. #1013
  This disables AbstractMemory.new, which has no practical use.
* Remove unused FFI::SizeTypes. #1022


1.15.5 / 2022-01-10
-------------------

Fixed:
* Fix long double argument or return values on 32bit i686. #849

1.15.1 / 2021-05-22
-------------------
