• Lower resource utilization, simpler memory management
• Constant expressions now properly handle errors
• A large amount of fixes (unhandled cases, LuaJIT FFI compatibility, etc.)
• Greatly expanded test suite
• Removed custom test runner (using just Lua)

Requirements:

• No changes

0.1.1

Changes:

• Build system enhancements
• CI enhancements
• We no longer ship a library/API (except a static library for embedded uses)
• Initial LuaRocks support (Windows support pending)
• Added option to disable tests

Requirements:

• No changes

Library clarification:

By default, you will only get a Lua module now. You can pass -Dstatic=true
to meson to switch the build to a static library; you will then get that
instead of a module. This is intended for systems that don't have Lua module
support - there you will want to link the FFI into the application instead.

It is not possible to build the static library and the module at the same
time, and usually the recommended thing is to build the module.

0.1.0 - Initial release

This is the initial release of the cffi module. It is of beta quality.
See STATUS.md for status and README.md for building and usage.

Production usage is currently not recommended, since the module is not
battle tested. Testing is highly encouraged.

Current requirements:

• Lua 5.1 - 5.4
• libffi
• meson 0.50+, optional pkg-config
• GCC 7+, Clang 8+ or Visual Studio 2017+ with updates recommended
  • Theoretical minimum is GCC 4.8, Clang 3.4 or any compiler with enough C++14
