This is probably the most important change in this release and allows `icyc` to be used to its full potential. +- Store parameter objects in such a way that changes to a parameter object do not affect other threads that use the same parameter object. + + The specific requirement from R7RS is: + + > `parameterize` must not change the associated values of any parameters in any thread other than the current thread and threads created inside the `parameterize` body. + +- Added bignum support to SRFI 60 - integers as bits. +- Normalize the result of `string->number` such that bignums are only returned if the result truly is a bignum. +- Allow Cyclone to find `(cyclone)` prefixed libraries installed in Cyclone's system folder. +- Allow a library to export identifiers that are exported by another library. Previously a library could only export identifiers that it defined directly. +- Raise an error if an unknown identifier is found in a library's `export` list. +- Aric Belsito removed a hardcoded call to `cyclone` from the Makefile when building `generate-c`. Thanks! +- Allow `cyclone` to inline character comparison functions (`char=?`, etc) when only two arguments are present, for a significant speed improvement. + +Bug Fixes + +- Prevent exception handlers from being accidentally collected when the collector cooperates on behalf of a mutator. +- Fixed a regression where `string->number` returns `0` on bad input instead of `#f`.
