[dependabot[bot]]

Bumps apispec from 4.7.1 to 5.1.1.

Changelog

Sourced from apispec's changelog.

5.1.1 (2021-09-27)

---

Bug fixes:

• Fix field ordering in "ordered" schema classes documentation (:issue:714).

Other changes:

• Don't build universal wheels. We don't support Python 2 anymore. (:pr:705)
• Make the build reproducible (:pr:[#669](https://github.com/marshmallow-code/apispec/issues/669)).

5.1.0 (2021-08-10)

---

Features:

• Add lazy option to component registration methods. This allows to add components to the spec only if they are actually referenced. (:pr:702)
• Add BasePlugin.header_helper and MarshmallowPlugin.header_helper (:pr:703).

Bug fixes:

• Ensure plugin helpers get component copies. Avoids issues if a plugin helper mutates its inputs. (:pr:704)

5.0.0 (2021-07-29)

---

Features:

• Rename doc_default to default. Since schema metadata is namespaced in a single metadata parameter, there is no name collision with default parameter anymore (:issue:687).
• Don't build schema component reference in OpenAPIConverter.resolve_nested_schema. This is done later in Components (:pr:700).
• MarshmallowPlugin: resolve schemas in allOf, oneOf, anyOf and not (:pr:701). Thanks :user:stefanv for the initial work on this.

Other changes:

• Refactor Components methods to make them consistent. Use component_id rather than name, remove **kwargs when unused. (:pr:696)

5.0.0b1 (2021-07-22)
