### [`v0.29.0`](https://github.com/tafia/quick-xml/blob/HEAD/Changelog.md#&#8203;0290----2023-06-13)

[Compare Source](tafia/quick-xml@v0.28.2...v0.29.0)

##### New Features

-   [#&#8203;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.
-   [#&#8203;606]: Implement indentation for `AsyncWrite` trait implementations.

##### Bug Fixes

-   [#&#8203;603]: Fix a regression from [#&#8203;581] that an XML comment or a processing
    instruction between a <!DOCTYPE> and the root element in the file brokes
    deserialization of structs by returning `DeError::ExpectedStart`
-   [#&#8203;608]: Return a new error `Error::EmptyDocType` on empty doctype instead
    of crashing because of a debug assertion.

##### Misc Changes

-   [#&#8203;594]: Add a helper macro to help deserialize internally tagged enums
    with Serde, which doesn't work out-of-box due to serde limitations.
