## Unreleased
## 0.23.1 -- 2022-09-11
### Bug Fixes
- [#469]: Fix incorrect parsing of CDATA and comments when using buffered readers
[#469]: https://github.com/tafia/quick-xml/issues/469
## 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 `unit`s 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 `unit`s from text and CDATA content.
`DeError::InvalidUnit` variant is removed, because after fix it is no longer used
- fix: `ElementWriter`, introduced in [#274](https://github.com/tafia/quick-xml/pull/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](https://github.com/tafia/quick-xml/issues/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](https://github.com/tafia/quick-xml/issues/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](https://github.com/Mingun/fast-xml/pull/4))
- test: properly test all paths of attributes parsing ([#4](https://github.com/Mingun/fast-xml/pull/4))
- feat: attribute iterator now implements `FusedIterator` ([#4](https://github.com/Mingun/fast-xml/pull/4))
- fix: fixed many errors in attribute parsing using iterator, returned from `attributes()`
or `html_attributes()` ([#4](https://github.com/Mingun/fast-xml/pull/4))
