## Features

### Improved property-merging behavior with `allOf`

When using `allOf` to extend a base object type, `openapi-python-client`
is now able to handle some kinds of modifications to an existing
property that would have previously caused an error:

- Overriding attributes that do not affect validation, such as
`description`.
- Combining properties that this generator ignores, like `maxLength` or
`pattern`.
- Combining a generic numeric type with `int` (resulting in `int`).
- Adding a `format` to a string.
- Combining `any` with a specific type (resulting in that specific
type).
- Adding or overriding a `default`

> [!NOTE]
> `pattern` and `max_length` are no longer fields on `StringProperty`,
which may impact custom templates.

This also fixes a bug where properties of inline objects (as opposed to
references) were not using the
merge logic, but were simply overwriting previous definitions of the
same property.

## Fixes

- Allow default values for properties of `Any` type

### Produce valid code for an object that has no properties at all

Fixed by PR #1109. Thanks @eli-bl!
