1# Changes: Development 2 3% STYLE GUIDELINES: 4% * Capitalize sentences 5% * Use imperative, e.g., Add, Improve, Change, etc. 6% * Don't use a period (.) at the end of entries 7% * If multiple sentences are needed, use a period or semicolon to divide sentences, but not at the end of the final sentence 8 9```{rubric} General: 10``` 11 12```{rubric} Configure/Build: 13``` 14 15- Make `SYCL` a `devicePackage`, i.e., builds `--with-sycl` now have `PETSC_HAVE_DEVICE` defined 16- Add the option `--with-devicelanguage` to compile `PetscDevice` code using either a C or C++ compiler 17 18```{rubric} Sys: 19``` 20 21```{rubric} Event Logging: 22``` 23 24```{rubric} PetscViewer: 25``` 26 27- Change the final argument of `PetscViewerGLVisSetFields()` to `PetscCtxDestroyFn *`. This means the destroy function must dereference the argument before operating on it 28 29```{rubric} PetscDraw: 30``` 31 32```{rubric} AO: 33``` 34 35```{rubric} IS: 36``` 37 38```{rubric} VecScatter / PetscSF: 39``` 40 41```{rubric} PF: 42``` 43 44```{rubric} Vec: 45``` 46 47```{rubric} PetscSection: 48``` 49 50```{rubric} PetscPartitioner: 51``` 52 53```{rubric} Mat: 54``` 55 56```{rubric} MatCoarsen: 57``` 58 59```{rubric} PC: 60``` 61 62- 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 63 64```{rubric} KSP: 65``` 66 67- Remove `KSPHPDDMPrecision` in favor of `PetscPrecision` 68 69```{rubric} SNES: 70``` 71 72```{rubric} SNESLineSearch: 73``` 74 75```{rubric} TS: 76``` 77 78```{rubric} TAO: 79``` 80 81```{rubric} PetscRegressor: 82``` 83 84```{rubric} DM/DA: 85``` 86 87- Change the final argument of `DMShellSetDestroyContext()` to `PetscCtxDestroyFn *`.
