## Release Notes Release Notes

In Polly 14 the following important changes have been incorporated.

- The command line option -polly-opt-fusion has been removed. What the flag does was frequently misunderstood and is rarely useful. However, the functionality is still accessible using

      -polly-isl-arg=--no-schedule-serialize-sccs

- The command line option -polly-loopfusion-greedy has been added. This will aggressively try to fuse any loop regardless of profitability. The is what users might have expected what -polly-opt-fusion=max would do.

- Support for gfortran-generated code has been removed. This includes Fortran Array Descriptors (-polly-detect-fortran-arrays) and the -polly-rewrite-byref-params pass.
