# Changes: Development

% STYLE GUIDELINES:
% * Capitalize sentences
% * Use imperative, e.g., Add, Improve, Change, etc.
% * Don't use a period (.) at the end of entries
% * If multiple sentences are needed, use a period or semicolon to divide sentences, but not at the end of the final sentence

```

- Make `SYCL` a `devicePackage`, i.e., builds `--with-sycl` now have `PETSC_HAVE_DEVICE` defined
- Add the option `--with-devicelanguage` to compile `PetscDevice` code using either a C or C++ compiler

- Add multi-precision support for MUMPS. One could use `-pc_precision <single, double>` to set the precision to be used by MUMPS, which can be different from `PetscScalar`'s precision

```{rubric} KSP:
```

- Remove `KSPHPDDMPrecision` in favor of `PetscPrecision`
