+- updated to version 1.13.1
+
+  1.13.1 / 2020-06-09
+  -------------------
+
+  Changed:
+  * Revert use of `ucrtbase.dll` as default C library on Windows-MINGW.
+    `ucrtbase.dll` is still used on MSWIN target. #790
+  * Test for `ffi_prep_closure_loc()` to make sure we can use this function.
+    This fixes incorrect use of system libffi on MacOS Mojave (10.14). #787
+  * Update types.conf on x86_64-dragonflybsd
+
+
+  1.13.0 / 2020-06-01
+  -------------------
+
+  Added:
+  * Add TruffleRuby support. Almost all specs are running on TruffleRuby and succeed. #768
+  * Add ruby source files to the java gem. This allows to ship the Ruby library code per platform java gem and add it as a default gem to JRuby. #763
+  * Add FFI::Platform::LONG_DOUBLE_SIZE
+  * Add bounds checks for writing to an inline char[] . #756
+  * Add long double as callback return value. #771
+  * Update type definitions and add types from stdint.h and stddef.h on i386-windows, x86_64-windows, x86_64-darwin, x86_64-linux, arm-linux, powerpc-linux. #749
+  * Add new type definitions for powerpc-openbsd and sparcv9-openbsd. #775, #778
+
+  Changed:
+  * Raise required ruby version to >= 2.3.
+  * Lots of cleanups and improvements in library, specs and benchmarks.
+  * Fix a lot of compiler warnings at the C-extension
+  * Fix several install issues on MacOS:
+    * Look for libffi in SDK paths, since recent versions of macOS removed it from `/usr/include` . #757
+    * Fix error `ld: library not found for -lgcc_s.10.4`
+    * Don't built for i386 architecture as it is deprecated
+  * Several fixes for MSVC build on Windows. #779
+  * Use `ucrtbase.dll` as default C library on Windows instead of old `msvcrt.dll`. #779
+  * Update builtin libffi to fix a Powerpc issue with parameters of type long
+  * Allow unmodified sourcing of (the ruby code of) this gem in JRuby and TruffleRuby as a default gem. #747
+  * Improve check to detect if a module has a #find_type method suitable for FFI. This fixes compatibility with stdlib `mkmf` . #776
+
+  Removed:
+  * Reject callback with `:string` return type at definition, because it didn't work so far and is not save to use. #751, #782
+
