 # 3.29.0 (2026-XX-XX)
 
  * Add documentation comments to attach metadata to nodes (experimental)
+ * Fix sequence destructuring of iterators throwing a `TypeError`
  * Add `TempestMarkdown` to use `tempest/markdown` as the `markdown_to_html` converter
  * Fix imported macros not resolving their own template-level macro imports
  * Add the `include_only` function to render a template without giving it access to the current context

+.. versionadded:: 3.29
+
+    Support for destructuring iterators was introduced in Twig 3.29.
+
+Sequence destructuring also works with iterators (any ``Traversable``
+value). Values are extracted in iteration order and keys are ignored. The
+iterator is consumed lazily: only as many values as there are variables are
+fetched, and the expression returns the iterator itself.
