All notable changes to this project will be documented in this file.
## ??? - Unreleased
- Expose `JANET_OUT_OF_MEMORY` as part of the Janet API.
- Add `native-deps` option to `decalre-native` in `jpm`. This lets native libraries link to other
native libraries when building with jpm.
- Remove the `tarray` module. The functionality of typed arrays will be moved to an external module
