-**Note**: due to changes to the way in which Gollum handles filenames, you may have to change some links in your wiki when migrating from gollum 4.x. See the [release notes](https://github.com/gollum/gollum/wiki/5.0-release-notes#migrating-your-wiki) for more details. You may be able to use the `bin/gollum-migrate-tags` script to accomplish this.
