New option -S (--dereference-files) to follow symbolic links only to files, not to directories, when using option -r for recursive search. Updated default recursive search to strictly perform -r without following any symbolic links (use -S to search symlinked files). New option --index for fast index-based search with the new ugrep-indexer tool. The ugrep-indexer tool is released on GitHub as a separate open source project at https://github.com/Genivia/ugrep-indexer which will become part of ugrep later after more feedback is received for this new feature.
