+title: 'Jekyll 3.9.1 Released'
+date: 2021-04-08 10:51:12 -0400
+author: parkr
+version: 3.9.1
+categories: [release]
+---
+
+This patch release of the 3.9 series is released to fix a bug where the
+`include` tag does not allow valid filename characters. For example, this
+would previously fail:
+
+{% raw %}
+```text
+{% include my-logo@2x.svg %}
+```
+{% endraw %}
+
+This release adds support for the following characters in filenames:
+
+- `@`
+- `-`
+- `(` and `)`
+- `+`
+- `~`
+- `#`
+
+Happy Jekylling!
