Released Cyclone Scheme 0.27

March 5th, 2021

Features

• Arthur Maciel added opaque? and opaque-null? predicates to (cyclone foreign).
• Added import-shared-object to (scheme eval) to allow loading a third party C shared library.
• Allow C compiler/linker options from a library to be expanded via cond-expand.

Bug Fixes

• Updated the runtime to avoid a race condition when creating new symbols. Thanks to Skye Soss for the bug report and patch.
• Prevent the compiler from inlining calls to primitives that open ports, avoiding a range of issues such as an open file operation being inlined across multiple places in the intermediate code. Thanks to Andy Arvanitis for the bug report.
• Arthur Maciel updated current-jiffy to use clock_gettime.
