I’m building a C shared library for the [current stable release: v1.3.1](https://julialang.org/downloads/#current_stable_release_v131_dec_30_2019) using Julia C API.

With new Julia versions in the future would I need to rebuild my library for new Julia versions or are they ABI compatible?

I’m using these functions from Julia C API:

- jl\_is\_initialized
- jl\_init
- jl\_atexit\_hook
- jl\_eval\_string
- jl\_string\_ptr
- jl\_isa
- jl\_is\_\*
- jl\_char\_type
- jl\_unbox\_\*
- jl\_exception\_occurred
