Bug Fixes

Misc Changes

0.37.0 -- 2024-10-27

New Features

#826: Implement From<String> and From<Cow<str>> for quick_xml::de::Text.
#826: Make SimpleTypeDeserializer and SimpleTypeSerializer public.
#826: Implement IntoDeserializer for &mut Deserializer.

Bug Fixes

#655: Do not write indent before and after $text fields and those $value fields that are serialized as a text (for example, usize or String).
#826: Handle only those boolean representations that are allowed by Xml Schema which is only "true", "1", "false", and "0". Previously the following values also was accepted:

bool XML content

true "True", "TRUE", "t", "Yes", "YES", "yes", "y"

false "False", "FALSE", "f", "No", "NO", "no", "n"

Misc Changes

#227: Split SeError from DeError in the serialize feature. Serialize functions and methods now return SeError.
#810: Return std::io::Error from Writer methods.
#811: Split NamespaceError and EncodingError from Error.
#811: Renamed Error::EscapeError to Error::Escape to match other variants.
#811: Narrow down error return type from Error where only one variant is ever returned: attribute related methods on BytesStart and BytesDecl returns AttrError
#820: Classify output of the Serializer by returning an enumeration with kind of written data
#823: Do not allow serialization of consequent primitives, for example Vec<usize> or Vec<String> in $value fields. They cannot be deserialized back with the same result
#827: Make escape and it variants take a impl Into<Cow<str>> argument and implement From<(&'a str, Cow<'a, str>)> on Attribute
#826: Removed DeError::InvalidInt, DeError::InvalidFloat and DeError::InvalidBoolean. Now the responsibility for returning the error lies with the visitor of the type. See rationale in serde-rs/serde#2811

0.36.2 -- 2024-09-20

Bug Fixes

#533: Fix incorrect DocType closing bracket detection when parsing with buffered reader

0.36.1 -- 2024-07-23

New Features

0.36.0 -- 2024-07-08

Bug Fixes

#781: Fix conditions to start CDATA section. Only uppercase <![CDATA[ can start it. Previously any case was allowed.

New Features

#772: Add reader::Config::allow_unmatched_ends to permit dangling end tags

Bug Fixes

#773: Fixed reporting incorrect end position in Reader::read_to_end family of methods and trimming of the trailing spaces in Reader::read_text when trim_text_start is set and the last event is not a Text event.
#771: Character references now allow any number of leading zeroes as it should. As a result, the following variants of quick_xml::escape::EscapeError are removed:
- TooLongDecimal
- TooLongHexadecimal
#771: Fixed Attribute::unescape_value which does not unescape predefined values since 0.32.0.
#774: Fixed regression since 0.33.0: Text event may be skipped in read_event_into() and read_event_into_async() in some circumstances.

Misc Changes

#771: EscapeError::UnrecognizedSymbol renamed to EscapeError::UnrecognizedEntity.
#771: Implemented PartialEq for EscapeError.
#771: Replace the following variants of EscapeError by InvalidCharRef variant with a new ParseCharRefError inside:

#763: Hide quick_xml::escape::resolve_html5_entity under escape-html feature again. This function has significant influence to the compilation time (10+ seconds or 5x times)

0.32.0 -- 2024-06-10

The way to configure parser is changed. Now all configuration is contained in the Config struct and can be applied at once. When serde-types feature is enabled, configuration is serializable.

The method of reporting positions of errors has changed - use error_position() to get an offset of the error position. For SyntaxErrors the range error_position()..buffer_position() also will represent a span of error.

The way of resolve entities with unescape_with are changed. Those methods no longer resolve predefined entities.

New Features

#513: Allow to continue parsing after getting new Error::IllFormed.
#677: Added methods config() and config_mut() to inspect and change the parser configuration. Previous builder methods on Reader / NsReader was replaced by direct access to fields of config using reader.config_mut().<...>.
#684: Added a method Config::enable_all_checks to turn on or off all well-formedness checks.
#362: Added escape::minimal_escape() which escapes only & and <.
#362: Added BytesCData::minimal_escape() which escapes only & and <.
#362: Added Serializer::set_quote_level() which allow to set desired level of escaping.
#705: Added NsReader::prefixes() to list all the prefixes currently declared.
#629: Added a default case to impl_deserialize_for_internally_tagged_enum macro so that it can handle every attribute that does not match existing cases within an enum variant.
#722: Allow to pass owned strings to Writer::create_element. This is breaking change!
#275: Added ElementWriter::new_line() which enables pretty printing elements with multiple attributes.
#743: Added Deserializer::get_ref() to get XML Reader from serde Deserializer
#734: Added helper functions to resolve predefined XML and HTML5 entities:
- quick_xml::escape::resolve_predefined_entity
- quick_xml::escape::resolve_xml_entity
- quick_xml::escape::resolve_html5_entity
#753: Added parser for processing instructions: quick_xml::reader::PiParser.
#754: Added parser for elements: quick_xml::reader::ElementParser.

Bug Fixes

#622: Fix wrong disregarding of not closed markup, such as lone <.
#684: Fix incorrect position reported for Error::IllFormed(DoubleHyphenInComment).
#684: Fix incorrect position reported for Error::IllFormed(MissingDoctypeName).
#704: Fix empty tags with attributes not being expanded when expand_empty_elements is set to true.
#683: Use local tag name when check tag name against possible names for field.
#753: Correctly determine end of processing instructions and XML declaration.

Misc Changes

#675: Minimum supported version of serde raised to 1.0.139
#675: Rework the quick_xml::Error type to provide more accurate information:
- Error::EndEventMismatch replaced by IllFormedError::MismatchedEndTag in some cases
- Error::EndEventMismatch replaced by IllFormedError::UnmatchedEndTag in some cases
- Error::TextNotFound was removed because not used
- Error::UnexpectedBang replaced by SyntaxError
- Error::UnexpectedEof replaced by SyntaxError in some cases
- Error::UnexpectedEof replaced by IllFormedError in some cases
- Error::UnexpectedToken replaced by IllFormedError::DoubleHyphenInComment
- Error::XmlDeclWithoutVersion replaced by IllFormedError::MissingDeclVersion (in #684)
- Error::EmptyDocType replaced by IllFormedError::MissingDoctypeName (in #684)
#684: Changed positions reported for SyntaxErrors: now they are always points to the start of markup (i. e. to the < character) with error. Use error_position() for that.
#684: Now <??> parsed as Event::PI with empty content instead of raising syntax error.
#684: Now <?xml?> parsed as Event::Decl instead of Event::PI.
#362: Now default quote level is QuoteLevel::Partial when using serde serializer.
#689: buffer_position() now always report the position the parser last seen. To get an error position use error_position().
#738: Add an example of how to deserialize XML elements into Rust enums using an intermediate custom deserializer.
#748: Implement Clone for DeEvent, PayloadEvent and Text.
#734: Rename NoEntityResolver to PredefinedEntityResolver.
#734: No longer resolve predefined entities (lt, gt, apos, quot, amp) in unescape_with family of methods. You should do that by yourself using the methods listed above.

0.31.0 -- 2023-10-22

MSRV bumped to 1.56! Crate now uses Rust 2021 edition.

Enum representation was changed (it was buggy anyway) to ensure compatibility with serde >= 1.0.181

New Features

#545: Resolve well-known namespaces (xml and xmlns) to their appropriate URIs. Also, enforce namespace constraints related to these well-known namespaces.
#635: Add support for async ElementWriter operations.

Bug Fixes

#660: Fixed incorrect deserialization of xs:lists from empty tags (<tag/> or <tag></tag>). Previously an DeError::UnexpectedEof") was returned in that case
#580: Fixed incorrect deserialization of vectors of newtypes from sequences of tags.
#661: More string handling of serialized primitive values (booleans, numbers, strings, unit structs, unit variants). <int>123<something-else/></int> is no longer valid content. Previously all data after 123 up to closing tag would be silently skipped.
#567: Fixed incorrect deserialization of vectors of enums from sequences of tags.
#671: Fixed deserialization of empty simpleTypes (for example, attributes) into Option fields: now they are always deserialized as Some("").

Misc Changes

#643: Bumped MSRV to 1.56. In practice the previous MSRV was incorrect in many cases.
#643: Adopted Rust 2021 edition.
#545: Added new Error variant -- Error::InvalidPrefixBind.
#651: Relax requirement for version of arbitrary dependency -- we're actually compatible with version 1.0.0 and up.
#649: Make features linkable and reference them in the docs.
#619: Allow to raise application errors in ElementWriter::write_inner_content (and newly added ElementWriter::write_inner_content_async of course).
#662: Get rid of some allocations during serde deserialization.
#665: Improve serialization of xs:lists when some elements serialized to an empty string.
#630: Fixed compatibility with serde >= 1.0.181

0.30.0 -- 2023-07-23

New Features

#609: Added Writer::write_serializable to provide the capability to serialize arbitrary types using serde when using the lower-level Writer API.
#615: Added ability to set entity resolver when deserialize using borrowing reader.
#617: Added ability to enforce the expansion of empty elements.

Bug Fixes

#604: Avoid crashing on wrong comments like <!--> when using read_event_into* functions.

Misc Changes

0.29.0 -- 2023-06-13

New Features

#601: Add serde_helper module to the crate root with some useful utility functions and document using of enum's unit variants as a text content of element.
#606: Implement indentation for AsyncWrite trait implementations.

Bug Fixes

#603: Fix a regression from #581 that an XML comment or a processing instruction between a <!DOCTYPE> and the root element in the file broke deserialization of structs by returning DeError::ExpectedStart
#608: Return a new error Error::EmptyDocType on empty doctype instead of crashing because of a debug assertion.

Misc Changes

#594: Add a helper macro to help deserialize internally tagged enums with Serde, which doesn't work out-of-the-box due to serde limitations.

0.28.2 -- 2023-04-12

New Features

#581: Allow Deserializer to set quick_xml::de::EntityResolver for resolving unknown entities that would otherwise cause the parser to return an [EscapeError::UnrecognizedSymbol] error.

Misc Changes

#584: Export EscapeError from the crate
#581: Relax requirements for unsescape_* set of functions -- their now use FnMut instead of Fn for resolve_entity parameters, like Iterator::map from std.

0.28.1 -- 2023-03-19

Misc Changes

#579: ElementWriter.write_inner_content now uses a FnOnce instead of a more restrictive Fn closure

0.28.0 -- 2023-03-13

New Features

#541: (De)serialize specially named $text enum variant in externally tagged enums to / from textual content
#556: to_writer and to_string now accept ?Sized types
#556: Add new to_writer_with_root and to_string_with_root helper functions
#520: Add methods BytesText::inplace_trim_start and BytesText::inplace_trim_end to trim leading and trailing spaces from text events
#565: Allow deserialize special field names $value and $text into borrowed fields when use serde deserializer
#568: Rename Writer::inner into Writer::get_mut
#568: Add method Writer::get_ref
#569: Rewrite the Reader::read_event_into_async as an async fn, making the future Send if possible.
#571: Borrow element names (<element>) when deserialize with serde. This change allow to deserialize into HashMap<&str, T>, for example
#573: Add basic support for async byte writers via tokio's AsyncWrite.

Bug Fixes

#537: Restore ability to deserialize attributes that represents XML namespace mappings (xmlns:xxx) that was broken since #490
#510: Fix an error of deserialization of Option<T> fields where T is some sequence type (for example, Vec or tuple)
#540: Fix a compilation error (probably a rustc bug) in some circumstances. Serializer::new and Serializer::with_root now accepts only references to Writer.
#520: Merge consequent (delimited only by comments and processing instructions) texts and CDATA when deserialize using serde deserializer. DeEvent::Text and DeEvent::CData events was replaced by DeEvent::Text with merged content. The same behavior for the Reader does not implemented (yet?) and should be implemented manually
#562: Correctly set minimum required version of memchr dependency to 2.1
#565: Correctly set minimum required version of tokio dependency to 1.10
#565: Fix compilation error when build with serde <1.0.139

0.27.1 -- 2022-12-28

Bug Fixes

#530: Fix an infinite loop leading to unbounded memory consumption that occurs when skipping events on malformed XML with the overlapped-lists feature active.
#530: Fix an error in the Deserializer::read_to_end when overlapped-lists feature is active and malformed XML is parsed

0.27.0 -- 2022-12-25

New Features

#521: Implement Clone for all error types. This required changing Error::Io to contain Arc<std::io::Error> instead of std::io::Error since std::io::Error does not implement Clone.

Bug Fixes

#490: Ensure that serialization of map keys always produces valid XML names. In particular, that means that maps with numeric and numeric-like keys (for example, "42") no longer can be serialized because XML name cannot start from a digit

#500: Fix deserialization of top-level sequences of enums, like

<?xml version="1.0" encoding="UTF-8"?>
<!-- list of enum Enum { A, B, С } -->
<A/>
<B/>
<C/>

#514: Fix wrong reporting Error::EndEventMismatch after disabling and enabling .check_end_names
#517: Fix swapped codes for \r and \n characters when escaping them
#523: Fix incorrect skipping text and CDATA content before any map-like structures in serde deserializer, like
```
unwanted text<struct>...</struct>
```
#523: Fix incorrect handling of xs:lists with encoded spaces: they still act as delimiters, which is confirmed also by mature XmlBeans Java library
#473: Fix a hidden requirement to enable serde's derive feature to get quick-xml's serialize feature for edition = 2021 or resolver = 2 crates

Misc Changes

#490: Removed $unflatten= special prefix for fields for serde (de)serializer, because:
- it is useless for deserializer
- serializer was rewritten and does not require it anymore
This prefix allowed you to serialize struct field as an XML element and now replaced by a more thoughtful system explicitly indicating that a field should be serialized as an attribute by prepending @ character to its name
#490: Removed $primitive= prefix. That prefix allowed you to serialize struct field as an attribute instead of an element and now replaced by a more thoughtful system explicitly indicating that a field should be serialized as an attribute by prepending @ character to its name
#490: In addition to the $value special name for a field a new $text special name was added:
- $text is used if you want to map field to text content only. No markup is expected (but text can represent a list as defined by xs:list type)
- $value is used if you want to map elements with different names to one field, that should be represented either by an enum, or by sequence of enums (Vec, tuple, etc.), or by string. Use it when you want to map field to any content of the field, text or markup
Refer to documentation for details.
#521: MSRV bumped to 1.52.
#473: serde feature that used to make some types serializable, renamed to serde-types
#528: Added documentation for XML to serde mapping

0.26.0 -- 2022-10-23

Misc Changes

#481: Removed the uses of const fn added in version 0.24 in favor of a lower minimum supported Rust version (1.46.0). Minimum supported Rust version is now verified in the CI.
#489: Reduced the size of the package uploaded into the crates.io by excluding tests, examples, and benchmarks.

0.25.0 -- 2022-09-10

Bug Fixes

#469: Fix incorrect parsing of CDATA and comments when using buffered readers

Misc Changes

#468: Content of DeError::Unsupported changed from &'static str to Cow<'static, str>
#468: Ensure that map keys are restricted to only types that can be serialized as primitives

0.24.1 -- 2022-09-10

Bug Fixes

#469: Fix incorrect parsing of CDATA and comments when using buffered readers

0.24.0 -- 2022-08-28

New Features

#387: Allow overlapping between elements of sequence and other elements (using new feature overlapped-lists)
#393: New module name with QName, LocalName, Namespace, Prefix and PrefixDeclaration wrappers around byte arrays and ResolveResult with the result of namespace resolution
#180: Make Decoder struct public. You already had access to it via the Reader::decoder() method, but could not name it in the code. Now the preferred way to access decoding functionality is via this struct
#395: Add support for XML Schema xs:list
#324: Reader::from_str / Deserializer::from_str / from_str now ignore the XML declared encoding and always use UTF-8
#416: Add borrow() methods in all event structs which allows to get a borrowed version of any event

#437: Split out namespace reading functionality to a dedicated NsReader, namely:

Old function in `Reader`	New function in `NsReader`
	`read_event` -- borrow from input
	`read_resolved_event` -- borrow from input
	`read_event_into`
`read_namespaced_event`	`read_resolved_event_into`
	`resolve`
`event_namespace`	`resolve_element`
`attribute_namespace`	`resolve_attribute`

#439: Added utilities detect_encoding() and decode() under the quick-xml::encoding namespace.
#450: Added support of asynchronous tokio readers
#455: Change return type of all read_to_end* methods to return a span between tags
#455: Added Reader::read_text method to return a raw content (including markup) between tags
#459: Added a Writer::write_bom() method for inserting a Byte-Order-Mark into the document.
#467: The following functions made const:
- Attr::key
- Attr::value
- Attributes::html
- Attributes::new
- BytesDecl::from_start
- Decoder::encoding
- LocalName::into_inner
- Namespace::into_inner
- Prefix::into_inner
- QName::into_inner
- Reader::buffer_position
- Reader::decoder
- Reader::get_ref
- Serializer::new
- Serializer::with_root
- Writer::new

Bug Fixes

#9: Deserialization erroneously was successful in some cases where error is expected. This broke deserialization of untagged enums which rely on error if variant cannot be parsed
#387: Allow to have an ordinary elements together with a $value field
#387: Internal deserializer state can be broken when deserializing a map with a sequence field (such as Vec<T>), where elements of this sequence contains another sequence. This error affects only users with the serialize feature enabled
#393: Now event_namespace, attribute_namespace and read_event_namespaced returns ResolveResult::Unknown if prefix was not registered in namespace buffer
#393: Fix breaking processing after encounter an attribute with a reserved name (started with "xmlns")
#363: Do not generate empty Event::Text events
#412: Fix using incorrect encoding if read_to_end family of methods or read_text method not found a corresponding end tag and reader has non-UTF-8 encoding
#421: Fix incorrect order of unescape and decode operations for serde deserializer: decoding should be first, unescape is the second
#421: Fixed unknown bug in serde deserialization of externally tagged enums when an enum variant represented as a Text event (i.e. <xml>tag</xml>) and a document encoding is not an UTF-8
#434: Fixed incorrect error generated in some cases by serde deserializer
#445: Use local name without namespace prefix when selecting enum variants based on element names in a serde deserializer

Misc Changes

#8: Changes in the error type DeError:

Variant	Change
~~`DeError::Text`~~	Removed because never raised
~~`DeError::InvalidEnum`~~	Removed because never raised
`DeError::Xml`	Renamed to `DeError::InvalidXml` for consistency with `DeError::InvalidBoolean`
`DeError::Int`	Renamed to `DeError::InvalidInt` for consistency with `DeError::InvalidBoolean`
`DeError::Float`	Renamed to `DeError::InvalidFloat` for consistency with `DeError::InvalidBoolean`
`DeError::Start`	Renamed to `DeError::UnexpectedStart` and tag name added to an error
`DeError::End`	Renamed to `DeError::UnexpectedEnd` and tag name added to an error
`DeEvent::Eof`	Renamed to `DeError::UnexpectedEof`
`DeError::EndOfAttributes`	Renamed to `DeError::KeyNotFound`
`DeError::ExpectedStart`	Added

#391: Added code coverage
#393: event_namespace and attribute_namespace now accept QName and returns ResolveResult and LocalName, read_event_namespaced now returns ResolveResult instead of Option<[u8]>
#393: Types of Attribute::key and Attr::key() changed to QName
#393: Now BytesStart::name() and BytesEnd::name() returns QName, and BytesStart::local_name() and BytesEnd::local_name() returns LocalName
#191: Remove unused reader.decoder().decode_owned(). If you ever used it, use String::from_utf8 instead (which that function did)
#191: Remove *_without_bom methods from the Attributes struct because they are useless. Use the same-named methods without that suffix instead. Attribute values cannot contain BOM
#191: Remove Reader::decode() and Reader::decode_without_bom(), they are replaced by Decoder::decode() and nothing. Use reader.decoder().decode_*(...) instead of reader.decode_*(...) for now. Reader::encoding() is replaced by Decoder::encoding() as well
#180: Eliminated the differences in the decoding API when feature encoding enabled and when it is disabled. Signatures of functions are now the same regardless of whether or not the feature is enabled, and an error will be returned instead of performing replacements for invalid characters in both cases.

Previously, if the encoding feature was enabled, decoding functions would return Result<Cow<&str>> while without this feature they would return Result<&str>. With this change, only Result<Cow<&str>> is returned regardless of the status of the feature.
#180: Error variant Error::Utf8 replaced by Error::NonDecodable
#118: Remove BytesStart::unescaped* set of methods because they could return wrong results Use methods on Attribute instead
#403: Remove deprecated quick_xml::de::from_bytes and Deserializer::from_borrowing_reader
#412: Rename methods of Reader:

Old Name New Name

read_event read_event_into

read_to_end read_to_end_into

read_text read_text_into

read_event_unbuffered read_event

read_to_end_unbuffered read_to_end
#412: Change read_to_end* and read_text_into to accept QName instead of AsRef<[u8]>
#415: Changed custom entity unescaping API to accept closures rather than a mapping of entity to replacement text. This avoids needing to allocate a map and provides the user with more flexibility.
#415: Renamed functions for consistency across the API:

Old Name New Name

*_with_custom_entities *_with

BytesText::unescaped() BytesText::unescape()

Attribute::unescaped_* Attribute::unescape_*
#329: Also, that functions now borrow from the input instead of event / attribute
#416: BytesStart::to_borrowed renamed to BytesStart::borrow, the same method added to all events
#421: decode_and_unescape* methods now does one less allocation if unescaping is not required
#421: Removed ability to deserialize byte arrays from serde deserializer. XML is not able to store binary data directly, you should always use some encoding scheme, for example, HEX or Base64
#421: All unescaping functions now accepts and returns strings instead of byte slices
#423: All escaping functions now accepts and returns strings instead of byte slices
#423: Removed BytesText::from_plain because it internally did escaping of a byte array, but since now escaping works on strings. Use BytesText::new instead
#428: Removed BytesText::escaped(). Use .as_ref() provided by Deref impl instead.
#428: Removed BytesText::from_escaped(). Use constructors from strings instead, because writer anyway works in UTF-8 only
#428: Removed BytesCData::new(). Use constructors from strings instead, because writer anyway works in UTF-8 only
#428: Changed the event and Attributes constructors to accept a &str slices instead of &[u8] slices. Handmade events has always been assumed to store their content UTF-8 encoded.
#428: Removed Decoder parameter from _and_decode versions of functions for BytesText (remember, that those functions was renamed in #415).

#431: Changed event constructors:

Old names	New name
`BytesStart::owned_name(impl Into<Vec<u8>>)`	`BytesStart::new(impl Into<Cow<str>>)`
`BytesStart::borrowed_name(&[u8])`	(as above)
`BytesStart::owned(impl Into<Vec<u8>>, usize)`	`BytesStart::from_content(impl Into<Cow<str>>, usize)`
`BytesStart::borrowed(&[u8], usize)`	(as above)
`BytesEnd::owned(Vec<u8>)`	`BytesEnd::new(impl Into<Cow<str>>)`
`BytesEnd::borrowed(&[u8])`	(as above)
`BytesText::from_escaped(impl Into<Cow<[u8]>>)`	`BytesText::from_escaped(impl Into<Cow<str>>)`
`BytesText::from_escaped_str(impl Into<Cow<str>>)`	(as above)
`BytesText::from_plain(&[u8])`	`BytesText::new(&str)`
`BytesText::from_plain_str(&str)`	(as above)
`BytesCData::new(impl Into<Cow<[u8]>>)`	`BytesCData::new(impl Into<Cow<str>>)`
`BytesCData::from_str(&str)`	(as above)

#440: Removed Deserializer::from_slice and quick_xml::de::from_slice methods because deserializing from a byte array cannot guarantee borrowing due to possible copying while decoding.
#455: Removed Reader::read_text_into which is just a thin wrapper over match on Event::Text
#456: Reader and writer stuff grouped under reader and writer modules. You still can use re-exported definitions from a crate root
#459: Made the Writer::write() method non-public as writing random bytes to a document is not generally useful or desirable.
#459: BOM bytes are no longer emitted as Event::Text. To write a BOM, use Writer::write_bom().
#467: Removed Deserializer::new because it cannot be used outside of the quick-xml crate

New Tests

#9: Added tests for incorrect nested tags in input
#387: Added a bunch of tests for sequences deserialization
#393: Added more tests for namespace resolver
#393: Added tests for reserved names (started with "xml"i) -- see https://www.w3.org/TR/xml-names11/#xmlReserved
#363: Add tests for Reader::read_event_impl to ensure that proper events generated for corresponding inputs
#407: Improved benchmark suite to cover whole-document parsing, escaping and unescaping text
#418: Parameterized macrobenchmarks and comparative benchmarks, added throughput measurements via criterion
#434: Added more tests for serde deserializer
#443: Now all documents in /tests/documents are checked out with LF eol in working copy (except sample_5_utf16bom.xml)

Legend:

feat: A new feature

fix: A bug fix

docs: Documentation only changes

style: White-space, formatting, missing semi-colons, etc

refactor: A code change that neither fixes a bug nor adds a feature

perf: A code change that improves performance

test: Adding missing tests

chore: Changes to the build process or auxiliary tools/libraries/documentation

0.23.1 -- 2022-09-11
