Cyclone-Winds contains a growing list of packages and is an easy way to distribute programs and libraries built using Cyclone. + +The `cyclone-winds` binary is installed as part of our [bootstrap](https://github.com/justinethier/cyclone-bootstrap) installation. Alternatively it can be built and installed separately if you already have a copy of Cyclone installed, though version 0.18 or higher is required. + +Please visit the [Cyclone-Winds](https://github.com/cyclone-scheme/cyclone-winds) site for more information. + +Features + +- Added the `(cyclone foreign)` library to make it easier to integrate with C code using the FFI. +- Arthur Maciel improved how `icyc` handles the "-p" flag, to now read/evaluate all expressions passed. + +Bug Fixes + +- Added a void type and a new supporting function `(void)`. A void object is also now returned in situations where the return value is undefined: `for-each` and `if` expressions with out an else clause. +- Allow `open-binary-input-file` and `open-binary-output-file` to be accessible via the REPL. +- Fix `bytevector?` predicate which was accidentally aliased to `vector?`. +- Fix `list-copy` to return a non-list object instead of raising an error, per R7RS. +- Fixed `eqv?` to use R7RS semantics to ensure equality of different instances of the same numeric value. The function was previously just an alias of `eq?`. +- Support two-argument version of `atan`. +- Support `start` and `end` arguments to `write-string`. +- Updated the string comparison procedures (EG: `string=?`) to support more than two arguments.
