All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

• Improved trailing comma handling in endpoint generation (#178 & #179). Thanks @dtkav!
• Optional is now properly imported for nullable fields (#177 & #180). Thanks @dtkav!

• Support for octet-stream content type (#116)
• Support for nullable (#99)
• Union properties can be defined using oneOf (#98)
• Support for lists of strings, integers, floats and booleans as responses (#165). Thanks @Maistho!

• All values that become file/directory names are sanitized to address path traversal vulnerabilities (CVE-2020-15141)
• All values that get placed into python files (everything from enum names, to endpoint descriptions, to default values) are validated and/or saniziatied to address arbitrary code execution vulnerabilities (CVE-2020-15142)

• Due to security concerns/implementation complexities, default values are temporarily unsupported for any RefProperty that doesn't refer to an enum.
• Defaults for properties must now be valid values for their respective type (e.g. "example string" is an invalid default for an integer type property, and the function for an endpoint using it would fail to generate and be skipped).

• Added support for header parameters (#117)

• JSON bodies will now be assigned correctly in generated clients(#139 & #147). Thanks @pawamoy!

• Added project_name_override and package_name_override config options to override the name of the generated project/package (#123)
• The generated library's version is now the same as the OpenAPI doc's version (#134)

• Relative paths are now allowed in securitySchemes/OAuthFlow/tokenUrl (#130).
• Schema validation errors will no longer print a stack trace (#131).
• Invalid YAML/URL will no longer print stack trace (#128)

• When encountering a problem, the generator will now differentiate between warnings (things it was able to skip past) and errors (things which halt generation altogether).

• The generator can now handle many more errors gracefully, skipping the things it can't generate and continuing with the pieces it can.
• Support for Enums declared in "components/schemas" and references to them (#102).
• Generated clients can now be installed via pip (#120).
• Support for YAML OpenAPI documents (#111)

• Switched OpenAPI document parsing to use Pydantic based on a vendored version of openapi-schema-pydantic (#103).
• Tests can now be run on Windows.

• Support for responses with no content (#63 & #66). Thanks @acgray!
• Support for custom string formats (#64 & #65). Thanks @acgray!

• Support for Python 3.7 (#58)

• Classes generated to be included within lists will now be named like Item. For example, if a property named "statuses" is an array of enum values, previously the Enum class declared would be called "Statuses". Now it will be called "StatusesItem". If a "title" attribute was used in the OpenAPI document, that should still be respected and used instead of the generated name. You can restore previous names by adding "StatusesItem" to the class_overrides section of a config file.
• Clients now require httpx ^0.13.0 (up from ^0.12.1). See httpx release notes for details.

• Support for binary format strings (file payloads)
• Support for multipart/form bodies
• Support for any supported property within a list (array), including other lists.
• Support for Union types ("anyOf" in OpenAPI document)
• Support for more basic response types (integer, number, boolean)
• Support for duplicate enums. Instead of erroring, enums with the same name (title) but differing values will have a number appended to the end. So if you have two conflicting enums named MyEnum, one of them will now be named MyEnum1. Note that the order in which these are processed and therefore named is entirely dependent on the order they are read from the OpenAPI document, so changes to the document could result in swapping the names of conflicting Enums.

• The way most imports are handled was changed which should lead to fewer unused imports in generated files.
• Better error messages
  • Most error messages will contain some useful information about why it failed instead of a stack trace
  • Client will still be generated if there are recoverable errors, excluding endpoints that had those errors
• Output from isort and black when generating will now be suppressed

• Defaults within models dataclasses for Dict or List properties will now be properly declared as a field with the default_factory parameter to prevent errors related to mutable defaults.

• Link to the GitHub repository from PyPI (#26). Thanks @theY4Kman!
• Support for date properties (#30, #37). Thanks @acgray!
• Allow naming schemas by property name and Enums by title (#21, #31, #38). Thanks @acgray!
