v2.0

• Ignore options are all now all behind a single flag, --ignore. For example, to ignore case and nonalpha characters you would previously have written --ignore-case --ignore-nonalpha, or -ia for short. Now you should write --ignore case nonalpha or -i c na. Some of the ignores have been renamed too -- see --help for details.
• The option to ignore letter order has been removed, it wasn't useful.
• Various deprecated aliases for ignore options have now been removed: --filter (use ignore regex), --filter-titles (use ignore titles), --as-latin (use ignore nonlatin), and --sort-words (use ignore words order).
• The fuzzy method flag has been renamed from --fuzzy to --method. It now defaults to an exact match.
• The short option for --threshold was previously -r, but it is now -t.
• Input is no longer accepted from STDIN.
• Output now defaults to including all fields from both input files, instead of only the fields used for the match.
• Added option to ignore leading and tailing words.
• Added support for blocking.
• Many operations will be faster.
• Improved remaining time display.
