Backwards compatibility

We aim to support the last two stable releases of DOLFINx. Sometimes features are supported for longer if need be.

Some features might depend on functionality added to DOLFINx, which means that they won’t be backwards compatible.

Workarounds for API differences between DOLFINx versions live in fenicsx-compat, which scifem depends on. It requires DOLFINx 0.10 or newer and Python 3.12 or newer.
