v0.3.0

• #176: Enabled autolink extension for cmark-gfm, so now we're finding strings like www.google.com or https://google.com, treating them as links and checking.
• #175: Reorganize top-level config keys.
• #178: Rename exclusion-related config options.
• #183: Add support for image links.
• #199: Now annotation <!-- xrefcheck: ignore all --> instead of <!-- xrefcheck: ignore file --> should be used to disable checking for links in file, so it's clearer that file itself is not ignored (and links can target it).
• #215: Now we notify user when there are scannable files that were not added to Git yet. Also added CLI option --include-untracked to scan such files and treat as existing.
• #191: Now we consider slash / (and only it) as path separator in local links for all OS, so xrefcheck's report is OS-independent. Use utf-8 compatible codepage on Windows.
• #224: Now the program output does not contain unicode characters that are not widely supported.
• #229: Now we call references to anchors in current file (e.g. [a](#b)) as file-local references instead of calling them current file (which was ambiguous).
• #233: Now xrefxcheck does not follow redirect links by default. It fails for permanent redirect responses (i.e. 301 and 308) and passes for temporary ones (i.e. 302, 303, 307).
• #231: Anchor analysis takes now into account the appropriate case-sensitivity depending on the configured Markdown flavour.
• #254: Now the dump-config command does not overwrite a file unless explicitly told with a --force flag. Also, a --stdout flag allows to print the config to stdout instead.
• #250: Now the redirect behavior for external references can be modified via rules in the configuration file with the externalRefRedirects parameter.
• #261: Symlinks are now not processed by the scanner.
• #268: Added CLI option --color that enables ANSI colors in output. Changed the output coloring defaults to show colors when CI env variable is true.
• #271: Now Xrefcheck is able to follow relative redirects.
• #262: Now Xrefcheck includes a scanner that verifies the repository symlinks.
• #307: The output of Xrefcheck is now more legible. Add the --print-unix-paths (-u) flag to print paths in Unix style (with forward slashes) on all platforms.
