+title: 'Jekyll 3.4.3 Released'
+date: 2017-03-21 08:52:53 -0500
+author: pathawks
+version: 3.4.3
+categories: [release]

+
+Another one-PR patch update as we continue our quest to destroy all bugs. A
+fairly technical debriefing follows, but the TLDR is that we have updated the
+`uri_escape` filter to more closely follow the pre-v3.4.0 behavior.
+
+In [v3.4.0]({% link _posts/2017-01-18-jekyll-3-4-0-released.markdown %}), we
+moved away from using the deprecated
+[`URI.escape`](https://ruby-doc.org/stdlib-2.3.0/libdoc/uri/rdoc/URI/Escape.html#method-i-encode)
+in favor of
+[`Addressable::URI.encode`](http://www.rubydoc.info/gems/addressable/Addressable/URI#encode-class_method).
+This is what powers our [`uri_escape`
+filter](https://jekyllrb.com/docs/templates/).
+
+While this transition was mostly a smooth one, the two methods are not
+identical. While `URI.escape` was happy to escape any string,
+`Addressable::URI.encode` first turns the string into an `Addressable::URI`
+object, and will then escape each component of that object. In most cases, this
+difference was insignificant, but there were a few cases where this caused some
+unintended regressions when encoding colons.
+
+While **Addressable** can understand that something like `"/example :page"` is a
+relative URI, without the slash it cannot figure out how to turn
+`"example :page"` into an `Addressable::URI` object. `URI.escape` had no such
+objection. This lead to the following Liquid code working fine in Jekyll 3.3.x
+but breaking in 3.4.0:
+
+{% raw %}
+```liquid
+{{ "example :page" | uri_escape }}
+```
+{% endraw %}
+
+This was not an intended consequence of switching to **Addressable**.
+
+Fortunately, the solution was not complicated. **Addressable** has a method
+[`Addressable::URI.normalize_component`](http://www.rubydoc.info/gems/addressable/Addressable/URI#normalize_component-class_method)
+which will simply escape the characters in a string, much like `URI.escape`.
+
+Thanks to @cameronmcefee and @FriesFlorian for reporting
+[this issue](https://github.com/jekyll/jekyll/issues/5954).
+
+Happy Jekylling!
