## [0.1.11]

### Added

- TypeScript: `indent` config option for controlling output indentation (default `"  "`)

### Fixed

- Python: eliminated extra blank lines between if/elif blocks in tagged union `_from_dict`/`_to_dict` helpers

### Changed

- Bump sigil-stitch 0.5.3 → 0.6.6: adopt `$comment(expr)`, `$attr(expr)`, `%V` verbatim strings, structural braces, and `end_control_flow_no_newline()` across all generators

## [0.1.10]

### Changed

- Bump sigil-stitch to v0.5.3
- Use `else` for last isinstance branch in discriminated union `to_dict` helpers (pyright strict clean)

## [0.1.9]

### Added

- TypeScript: `toolchain = "vp"` config for vite-plus — generates `vite.config.ts` with type-aware linting, `vp pack` library build, and `vp check --no-fmt` type checking

### Fixed

- TypeScript: wildcard response codes (4XX, 5XX) now emit range checks instead of duplicate `status === 0` branches
- TypeScript: split import collection into request-only and response-only sets so `toJSON` is only imported for request body types
- TypeScript: empty-object `fromJSON`/`toJSON` converters use pass-through cast instead of empty destructure
- TypeScript: vp toolchain emits `.mjs`/`.d.mts` paths in `package.json` to match `vp pack` output
- Python: add `to_dict`/`from_dict` to allOf intersection dataclasses
- Python: serialize `list[Model]` request bodies with `to_dict` mapping
- Python: use comma-join for array query params instead of `str(list)`
- Python: recursively serialize Map values containing object types
- Go: populate `Status4XX`/`Status5XX` fields for wildcard response codes
- Go: emit `AdditionalProperties` field with `MarshalJSON`/`UnmarshalJSON`

### Changed

- Bumped sigil-stitch 0.5.0 → 0.5.1
- Internal: migrated raw `format!()` string building to sigil-stitch structured APIs (Go `TypeName`, `add_embedded`, Python `CodeBlock`, Rust `AnnotationSpec::args`)

## [0.1.8]

### Fixed

- TypeScript: avoid TS2783 compile error in camelCase mode by putting spread before discriminator literal in `fromJSON`/`toJSON` converters

## [0.1.7]

### Added

- Rust (aioduct): config-driven feature management via `[generators.rust-aioduct.aioduct]` section
  - `runtime` — select async runtime: `tokio` (default), `smol`, or `compio`
  - `tls` — TLS backend: `rustls-ring` (default), `rustls-aws-lc-rs`, or `"false"` to disable
  - `compression` — opt-in decompression codecs: `gzip`, `brotli`, `zstd`, `deflate`
  - `features` — pass-through feature flags (e.g. `tracing`, `http3`, `blocking`)
  - `version` — override the pinned aioduct version
- Rust (aioduct): generated client now uses `Client::with_rustls()` (or `with_http3()`) based on TLS config, fixing HTTPS support

### Changed

- Bumped aioduct dependency 0.1.6 → 0.1.8

### Fixed

- Rust: escape double quotes in Cargo.toml `description` field (fixes TOML parse errors when spec descriptions contain quotes)
- Rust: skip discriminator field in internally-tagged struct variants (fixes `serde(tag)` conflict)
- Rust: emit unit variants when all fields are the discriminator (e.g. `SetupUnspecified,` instead of `SetupUnspecified {}`)

## [0.1.6]

### Added

- TypeScript: `property_naming = "camelCase"` config generates dual-type model files with wire-format (`Name$Wire`) and ergonomic (`Name`) interfaces, plus `nameFromJSON` / `nameToJSON` converter functions
  - Covers Objects, TaggedUnions (internal, adjacent, external tagging), Intersections (allOf), and Unions (oneOf)
  - Externally-tagged unions use `if ('KEY' in json)` chains instead of switch statements
  - Barrel re-exports both types and converter functions automatically

### Fixed

- TypeScript: intersection `fromJSON` returns now use type assertion (`as Name`) for mixed object+enum allOf compositions
- TypeScript: two-pass convertible set computation correctly handles Intersection/Union schemas containing enum member refs
- TypeScript: non-convertible schemas (enums, simple aliases) no longer generate broken `$Wire` import references in camelCase mode
- TypeScript: reserved-word field names (e.g. `delete`, `class`) are correctly quoted in generated interfaces (sigil-stitch 0.5.0)

## [0.1.5]

### Added

- TypeScript: `emit_enum_constants` config for companion const objects (`export const Name = { KEY: 'val' as const, ... }`) alongside enum type aliases
- TypeScript: `emit_type_guards` config for `is*` type guard functions alongside tagged union type aliases (internal, adjacent, and external tagging)
- TypeScript: models barrel (`models/index.ts`) now emits value re-exports alongside type re-exports when features are enabled

## [0.1.4]

### Added

- Rust: native `[utoipa]` config section for automatic `utoipa::ToSchema` integration
  - Structs, string enums, integer enums, tagged unions, intersections, and aliases get `#[derive(utoipa::ToSchema)]`
  - Untagged and tagged unions (internal/adjacent) get manual `impl utoipa::PartialSchema + ToSchema` with `OneOfBuilder`
  - Adds `utoipa` to generated Cargo.toml dependencies automatically
- Rust: `[lints] workspace = true` emitted in generated Cargo.toml when `workspace_mode = true`
- Rust: `url` dependency is now conditional (only included when spec has query parameters) for reqwest and aioduct backends

### Fixed

- Rust: removed standalone `tokio` dependency from reqwest generated Cargo.toml
- Rust: variant schemas for internal/adjacent tagged unions are no longer inlined when utoipa is enabled (standalone types required for `PartialSchema` references)

## [0.1.3]

### Fixed

- Rust: API types referencing suppressed primitive aliases (e.g. schema "string") now resolve to the primitive type instead of emitting broken `crate::models::String` paths
- Rust: removed standalone `tokio` dependency from aioduct generated Cargo.toml (already pulled via aioduct's `"tokio"` feature)
- Rust: codegen warns when a qualified derive path (e.g. `utoipa::ToSchema`) has no matching `dependencies` entry

## [0.1.2]

### Added

- Rust: `workspace_deps` config with 3 modes (`explicit`, `workspace_version`, `full`) for generated Cargo.toml dependencies
- Rust: `per_type` extra derives for targeting specific schemas by name
- Rust: `package_name` accepted as alias for `crate_name` in generator config

### Fixed

- Rust: bogus `string.rs` no longer generated for schemas named "string" (was producing `pub type String = String;` that shadows std)
- Rust: multi-line operation summaries now correctly prefix every line with `///` (YAML `|-` block scalars)
- Rust: `#[serde(untagged)]` enums excluded from blanket `extra_derives.unions` (incompatible with utoipa::ToSchema)

## [0.1.1]

### Added

- Python: discriminator-aware `_from_dict()` / `_to_dict()` helpers for tagged unions (internal, adjacent, external)
- Rust: struct variants for internally/adjacently tagged enums (fields inlined into enum)

### Changed

- Rust: upgrade sigil-stitch 0.4.3 → 0.4.4 (fixes Display impl spacing)
- Rust: generated code now includes `// @generated` marker and `#![allow(clippy::all)]`
- Rust: dead standalone struct files no longer emitted for exclusively-inlined variants
- Rust: function signatures use `&[T]` instead of `&Vec<T>`
- Rust: query params URL-encoded via `url::form_urlencoded` (reqwest/aioduct)

### Fixed

- Rust: punctuation spacing in generated `Display` impls (`std:: fmt::` → `std::fmt::`)
- Rust: flaky golden tests from temp dir name collisions under parallelism
- Python: pyright strict-mode errors in generated tagged union helpers

## [0.1.0]

- Flattened Justfile layout, aligned CI with sibling projects
- TypeScript: replaced `any` with `unknown` across generated code and runtime
- TypeScript: named re-exports instead of barrel `export *`
- TypeScript: collapsed nullable+optional fields to two states

### Fixed
