Released Cyclone Scheme 0.31.0

July 27th, 2021

Properly handle vectors literals at the top level of compiled code. Previously this could lead to segmentation faults at runtime.
Fixed an off-by-one error unpacking arguments when calling a primitive as the continuation after a garbage collection.

Fixed read-line to prevent data loss when used in conjunction with other I/O functions (such as read-char) to read data from the same port. This was because the previous version of read-line used a different internal buffer than our other I/O functions.
Fixed a bug in make-list that consumed all available memory when passing a negative list length.
Allow a record type to contain fields that are not initialized by the constructor.
Built out numerator and denominator with code conforming to R7RS.

Updated thread-start! to return the given thread object, per SRFI 18.
thread-join! now returns the result of the thread it was waiting on, per SRFI 18.

Eliminate clang compiler warnings referencing EOF when building the runtime.
Updated runtime so the C compiler will no longer generate warnings regarding the string comparisons in Cyc_st_add. Previously this could result in these warnings being spammed to the console when compiling code using Cyclone.
Properly escape question marks within strings in generated C code to avoid trigraphs.
Avoid an “unused variable” warning from the C compiler when compiling certain recursive functions.
