# Changelog
All notable changes to this project will be documented in this file.
## Unreleased - ???
## 1.32.1 - 2023-10-15
- Fix return value from C function `janet_dobytes` when called on Janet functions that yield to event loop.
- Change C API for event loop interaction - get rid of JanetListener and instead use `janet_async_start` and `janet_async_end`.
- Rework event loop to make fewer system calls on kqueue and epoll.
- Expose atomic refcount abstraction in janet.h
