 ## [Unreleased]
+
+## [0.21.0] - 2025-10-04
 ### Added
 - `ParsingOptions::entity_resolver` can be used to resolve external entities referenced via public ID and URI.
 
 ### Changed
-- `Node::has_attribute`, `Node::attribute` and `Node::attribute_node` now match local names similar to how `Node::has_tag_name` works.
+- `Node::has_attribute`, `Node::attribute` and `Node::attribute_node` match local names similar to how `Node::has_tag_name` works.
+- Various internal performance improvements, e.g. devirtualization of token dispatch and usage of `memchr` for finding delimiters.
+
+### Fixed
+- Possible panic when entity resolution yields unbalanced tags.
+- Quadratic runtime when merging consecutive text nodes.
 
 ## [0.20.0] - 2024-05-23
