`v0.40.1`

Bug Fixes

#964: Fix unreachable!() panic in the serde deserializer when a DOCTYPE
declaration appears between two text runs inside an element (e.g.
<a>x<!DOCTYPE y>z</a>). The DOCTYPE used to break drain_text's
consecutive-text merge, so two DeEvent::Text events reached
read_text and tripped its "Cannot be two consequent Text events"
invariant. DOCTYPE is now treated as transparent during text drain —
it still goes through the entity resolver, but the surrounding text
is merged into one run. Discovered via libFuzzer on a real-world
SAML deserializer harness.

Misc Changes

`v0.40.0`

Compare Source

MSRV bumped to 1.79.

Now quick-xml supports the UTF-16 encoded documents. See the new DecodingReader type.

New Features

#956: Add DecodingReader, a BufRead adapter that auto-detects encoding
from BOM or XML declaration and transcodes to UTF-8. Enabled by the encoding feature.
#938: Add new enumeration XmlVersion and typified getter BytesDecl::xml_version().
#938: Add new error variant IllFormedError::UnknownVersion.
#371: Add new error variant EscapeError::TooManyNestedEntities.
#371: Improved compliance with the XML attribute value normalization process by adding
- Attribute::normalized_value()
- Attribute::normalized_value_with()
- Attribute::decoded_and_normalized_value()
- Attribute::decoded_and_normalized_value_with()
which ought to be used in place of deprecated
- Attribute::unescape_value()
- Attribute::unescape_value_with()
- Attribute::decode_and_unescape_value()
- Attribute::decode_and_unescape_value_with()
Deprecated functions now behaves the same as newly added.

Bug Fixes

#938: Use correct rules for EOL normalization in Deserializer when parse XML 1.0 documents.
Previously XML 1.1. rules was applied.

Misc Changes

#914: Remove deprecated .prefixes(), .resolve(), .resolve_attribute(), and .resolve_element()
of NsReader. Use .resolver().<...> methods instead.
#938: Now BytesText::xml_content, BytesCData::xml_content and BytesRef::xml_content
accepts XmlVersion parameter to apply correct EOL normalization rules.
#944: read_text() now returns BytesText which allows you to get the content with
properly normalized EOLs. To get the previous behavior use .read_text().decode()?.
#956: Bumped MSRV from 1.59 (Feb 2022) to 1.79 (June 2024)
