-fix: consecutive blockquotes blocks
+fix: double newline between consecutive blockquote syntax creates separate blockquotes
+
+Previously, for consecutive blockquotes they were rendered as one:
+
+**Input**
+
+```md
+> Block A.1
+> Block A.2
+
+> Block B.1
+```
+
+**Output**
+
+```html
+<blockquote>
+  <p>Block A.1</p>
+  <p>Block A.2</p>
+  <p>Block.B.1</p>
+</blockquote>
+```
+
+This is not compliant with the [GFM spec](https://github.github.com/gfm/#block-quotes) which states that consecutive blocks should be created if there is a blank line between them.
