## Unreleased - ???
- Silence warnings in some compilers.
- Allow passing a second argument to `disasm`.
- Add `cancel`. Resumes a fiber but makes it immediately error at the yield point.
- Allow multi-line paste into built in repl.
- Add `(curenv)`.
- Change `net/read`, `net/chunk`, and `net/write` to raise errors in the case of failures.
- Add `janet_continue_signal` to C API. This indirectly enables C functions that yield to the event loop
to raise errors or other signals.
@ -16,7 +20,7 @@ All notable changes to this project will be documented in this file.
- Expose `janet_cryptorand` in C API.
- Properly initialize PRF in default janet program
- Add `index-of` to core library.
- Add `-fPIC` back to core CFLAGS (non-optional when compiling default client with Makefile)
- Add `-fPIC` back to core CFLAGS (non-optional when compiling default client with Makefile)
- Fix defaults on Windows for ARM
- Fix defaults on NetBSD.
