## Breaking Changes

- URL-encode path parameters in generated endpoints (#1349)

## Fixes

### Fix bad code generation

#1360 by @EricAtORS

This fixes:
- missing parenthesis in to_multipart
 #1338 #1318
- missing imports in the lazy eval in to_multipart:
#931 and #1051

### Fix optional bodies

If a body is not required (the default), it will now:

1. Have `Unset` as part of its type annotation.
2. Default to a value of `UNSET`
3. Not be included in the request if it is `UNSET`

Thanks @orelmaliach for the report! Fixes #1354

Release 0.27.1 (#1345)

> [!IMPORTANT]

## Fixes

- Remove non-existent CHANGELOG.md references from UV and Poetry
templates (#1344)
- Initialize optional lists as UNSET, not [] (#1346)
- Correct docstring typos in client template (#1347)

### Update `uv_build` to 0.9

#1352 by @johnthagen

`uv` has been in the `0.9.x` release cycle for a while, so update
templates to use the corresponding `uv_build` range.

Release 0.27.0 (#1330)

> [!IMPORTANT]
> Merging this pull request will create this release

## Breaking Changes

### Drop support for Python 3.9

Both `openapi-python-client` itself and any generated clients no longer
support Python 3.9.

### Generated models now use `from __future__ import annotations`

This simplifies using forward references with the newer union syntax.

## Features

### Upgrade generated clients to 3.10 union syntax

All generated types now use the `A | B` syntax instead of `Union[A, B]`
or `Optional[A]`.

## Fixes

- Drop generated `requires-python` upper bounds for uv and PDM (#1329)

### Change default Ruff hook to `--fix-only`

This should enable `openapi-python-client` to keep auto-fixing lints
(like removing unused imports) but _not_ fail to
generate when unfixable lints are violated.

Since it's now unlikely for breaking changes to affect our usage (and by
popular request), the upper bound of `ruff`
has been lifted. Newer versions of `openapi-python-client` should no
longer be required to support newer versions of `ruff`.

## Notes

- Minimum Typer version is now 0.16

Release 0.26.0 (#1306)

> [!IMPORTANT]
> Merging this pull request will create this release

## Breaking Changes

### Change some union variant names

When creating a union with `oneOf`, `anyOf`, or a list of `type`, the
name of each variant used to be `type_{index}`
where the index is based on the order of the types in the union.

This made some modules difficult to understand, what is a
`my_type_type_0` after all?
It also meant that reordering union members, while not a breaking change
to the API, _would_ be a breaking change
for generated clients.

Now, if an individual variant has a `title` attribute, that `title` will
be used in the name instead.
This is only an enhancement for documents which use `title` in union
variants, and only a breaking change for
_inline models_ (not `#/components/schemas` which should already have
used more descriptive names).

Thanks @wallagib for PR #962!

## Features

### Support patterned and default HTTP statuses

HTTP statuses like `2XX` and `default` are now supported!
