Changelog

Sourced from quick-xml's changelog.

0.23.0 -- 2022-05-08

• feat: add support for i128 / u128 in attributes or text/CDATA content
• test: add tests for malformed inputs for serde deserializer
• fix: allow to deserialize units from any data in attribute values and text nodes
• refactor: unify errors when EOF encountered during serde deserialization
• test: ensure that after deserializing all XML was consumed
• feat: add Deserializer::from_str, Deserializer::from_slice and Deserializer::from_reader
• refactor: deprecate from_bytes and Deserializer::from_borrowing_reader because they are fully equivalent to from_slice and Deserializer::new
• refactor: reduce number of unnecessary copies when deserialize numbers/booleans/identifiers from the attribute and element names and attribute values
• fix: allow to deserialize units from text and CDATA content. DeError::InvalidUnit variant is removed, because after fix it is no longer used
• fix: ElementWriter, introduced in #274 (0.23.0-alpha2) now available to end users
• fix: allow lowercase <!doctype > definition (used in HTML 5) when parse document from &[u8]
• test: add tests for consistence behavior of buffered and borrowed readers
• fix: produce consistent error positions in buffered and borrowed readers
• feat: Error::UnexpectedBang now provide the byte found
• refactor: unify code for buffered and borrowed readers
• fix: fix internal panic message when parse malformed XML (#344)
• test: add tests for trivial documents (empty / only comment / <root>...</root> -- one tag with content)
• fix: CDATA was not handled in many cases where it should
• fix: do not unescape CDATA content because it never escaped by design. CDATA event data now represented by its own BytesCData type (quick-xml#311)
• feat: add Reader::get_ref() and Reader::get_mut(), rename Reader::into_underlying_reader() to Reader::into_inner()
• refactor: now Attributes::next() returns a new type AttrError when attribute parsing failed (#4)
• test: properly test all paths of attributes parsing (#4)
• feat: attribute iterator now implements FusedIterator (#4)
• fix: fixed many errors in attribute parsing using iterator, returned from attributes() or html_attributes() (#4)

0.23.0-alpha3

• fix: use element name (with namespace) when unflattening (serialize feature)
