 ### Permalinks no longer automatically add a trailing slash
 
-In Jekyll 2, any URL constructed from the `permalink:` field had a trailing slash (`/`) added to it automatically.  Jekyll 3 no longer adds a trailing slash automatically to `permalink:` URLs. This can potentially result in old links to pages returning a 404 error. For example, suppose a page previously contained the YAML `permalink: /:year-:month-:day-:title` that resulted in the URL `example.com/2016-02-01-test/` (notice the trailing slash), Jekyll internally generates a folder named `2016-02-01-test`. In Jekyll 3, the same `permalink:` generate the file `2016-02-01-test.html` and the URL for the same page will be `example.com/2016-02-01-test`, and consequently any links to the old URL will result in a 404 error. In order to maintain the same URLs and avoid this problem, a trailing slash should be added to the `permalink:` field, for example `permalink: /:year-:month-:day-:title/`.
