Released Cyclone Scheme 0.11.4

September 27th, 2019

Bug Fixes

• Modified the minor GC write barrier to only track mutations where a heap variable is modified to point to an object on the stack. This significantly improves performance of mutation operations: set!, set-car!, etc.
• Fixed an issue with make-string and UTF-8 chars. Thanks to Lassi Kortela for the bug report!
• Added open-binary-input-file and open-binary-output-file from R7RS.
• Validate the number of arguments passed to if expressions.
• Raise a useful error instead of aborting the whole program (!) when apply attempts to execute an object of the wrong type.
• Better handling of edge cases where an object of the wrong type is executed instead of a closure. Previously there were cases where this would cause the runtime to crash.
