+# Changelog
+
+All notable changes to XML.jl will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Added
+- New streaming tokenizer (`XMLTokenizer` module) for fine-grained XML token iteration.
+- XPath support via `xpath(node, path)`.
+- `test/test_libxml2_testcases.jl`: 243 test cases borrowed from the [libxml2](https://github.com/GNOME/libxml2) test suite covering CDATA, comments, processing instructions, attributes, namespaces, DTD internal subsets, entity references, whitespace handling, Unicode, error cases, and real-world document patterns.
+
+### Fixed
+- **Tokenizer: multi-byte UTF-8 in attribute values** — Parsing attribute values containing multi-byte UTF-8 characters (e.g., `<doc city="東京"/>`) could produce a `StringIndexError` because `attr_value()` used byte arithmetic (`ncodeunits - 1`) instead of `prevind` to strip quotes. The same issue existed in `_read_attr_value!`.
+- **Tokenizer: quotes inside DTD comments** — A `"` or `'` character inside a `<!-- -->` comment within a DTD internal subset caused the tokenizer to misinterpret it as a quoted string delimiter, leading to an "Unterminated quoted string" error. The DOCTYPE body parser now correctly skips comment content.
+
+## [0.3.8]
+
+### Fixed
+- `XML.write` now respects `xml:space="preserve"` and suppresses indentation for elements with this attribute ([#49]).
+
+## [0.3.7]
+
+### Fixed
+- Resolved remaining issues from [#45] and fixed [#46] (whitespace preservation edge cases) ([#47]).
+
+## [0.3.6]
+
+### Added
+- `XML.write` respects `xml:space="preserve"` on elements, suppressing automatic indentation ([#45]).
+
+### Fixed
+- `String` type ambiguity on Julia nightly resolved ([#38]).
+
+## [0.3.5]
+
+### Fixed
+- `depth` and `parent` functions corrected to work properly with the DOM tree API ([#37]).
+- `escape` updated to no longer be idempotent — every `&` is now escaped, matching spec behavior ([#32], addressing [#31]).
+- `pushfirst!` support added for `Node` children ([#29]).
+
+## [0.3.4]
+
+### Fixed
+- Fixed [#26].
+- CI updated to use `julia-actions/cache@v4` and `lts` Julia version.
+
+## [0.3.3]
+
+### Added
+- `h` constructor for concise element creation (e.g., `h.div("hello"; class="main")`).
+
+### Fixed
+- Path definition error in README example ([#20]).
+
+## [0.3.2]
+
+### Fixed
+- Minor typos.
+
+## [0.3.1]
+
+### Added
+- Julia 1.6 compatibility ([#16]).
+
+### Changed
+- Smarter escaping logic.
+
+## [0.3.0]
+
+### Changed
+- Attribute internal representation changed from `Dict` to `OrderedDict` (later reverted to `Vector{Pair}`).
+
+## [0.2.3]
+
+### Fixed
+- Parse method fix.
+
+## [0.2.2]
+
+### Added
+- DTD parsing via `parse_dtd`.
+- `is_simple` and `simple_value` exports.
+- `setindex!` methods for modifying attributes.
+- `unescape` function.
+
+### Fixed
+- DOCTYPE parsing made case-insensitive.
+
+## [0.2.1]
+
+### Fixed
+- Write output fixes.
+
+## [0.2.0]
+
+### Changed
+- Major rewrite: introduced `NodeType` enum, `Node{S}` parametric struct, callable `NodeType` constructors, and `XML.write`.
+- Processing instruction support.
+- Benchmarks added.
+
+## [0.1.3]
+
+### Changed
+- Improved print output for `AbstractXMLNode`.
+
+## [0.1.2]
+
+### Added
+- AbstractTrees 0.4 compatibility ([#5]).
+
+## [0.1.1]
+
+### Added
+- `Node` implementation with `print_tree`.
+- Color output in REPL display.
+- Stopped stripping whitespace from text nodes.
+
+## [0.1.0]
+
+- Initial release.
