post	Released Cyclone Scheme 0.5.1	The main focus of `0.5.1` is performance but this is also the first release to provide installation instructions for Linux, Mac, and Windows.

Features

• Thanks to Kashyap for adding build instructions for Windows (MSYS) and Mac!

• Allow define-c function definitions to optionally provide an additional non-CPS form of the function. This form is more efficient and will be used by compiled code whenever possible.

• Improved the compiler's CPS optimization phase to eliminate more unnecessary function calls.

• Modified the GC to allow a given number of "huge" allocations to trigger GC. Previously GC was only triggered when smaller heap regions were below a certain percentage of free memory.

• Compiled code now directly accesses boxed mutable variables instead of using a wrapper function.

• Added command line options to icyc for evaluating an S-expression from the command line and for running as a script without the Cyclone banner text.

Bug Fixes

• Prevent potential memory corruption when working with large vectors that cannot be allocated on the stack.
