500- A whole host of examples added, as well as a lengthy explainer of the trait patterns.
501
502## [0.4.1] - 2025-10-13
503
504### Added
505
506**Collection trait improvements** (`jacquard-api`)
507- Generated `{Type}Record` marker structs for all record types
508- Each implements `XrpcResp` with `Output<'de> = {Type}<'de>` and `Err<'de> = RecordError<'de>`
509- Enables typed `get_record` returning `Response<R::Record>`
510
511### Changed
512
513- Minor improvements to derive macros (`jacquard-derive`)
514- Identity resolution refinements (`jacquard-identity`)
515- OAuth client improvements (`jacquard-oauth`)

519## [0.4.0] - 2025-10-11
520
521### Breaking Changes
522
523**Zero-copy deserialization** (`jacquard-common`, `jacquard-api`)
524- `XrpcRequest` now takes a `'de` lifetime parameter and requires `Deserialize<'de>`
525- For raw data, `Response::parse_data()` gives validated loosely-typed atproto data, while `Response::parse_raw()` gives the raw values, with minimal validation.
526
527**XRPC module moved** (`jacquard-common`)
528- `xrpc.rs` is now top-level instead of under `types`
529- Import from `jacquard_common::xrpc::*` not `jacquard_common::types::xrpc::*`
530
531**Response API changes** (`jacquard-common`)
532- `XrpcRequest::Output` and `XrpcRequest::Err` are associated types with lifetimes
533- Split response and request traits: `XrpcRequest<'de>` for client, `XrpcEndpoint` for server
534- Added `XrpcResp` marker trait
535
536**Various traits** (`jacquard`, `jacquard-common`, `jacquard-lexicon`, `jacquard-oauth`)
537- Removed #[async_trait] attribute macro usage in favour of `impl Future` return types with manual bounds.
538- Boxing imposed by asyc_trait negatively affected borrowing modes in async methods.
539- Currently no semver guarantees on API trait bounds, if they need to tighten, they will.
540
541### Added
542
543**New crate: `jacquard-axum`**
544- Server-side XRPC handlers for Axum
545- `ExtractXrpc<R>` deserializes incoming requests (query params for Query, body for Procedure)
546- Automatic error responses
547
548**Lexicon codegen fixes** (`jacquard-lexicon`)
549- Union variant collision detection: when multiple namespaces have similar type names, foreign ones get prefixed (e.g., `Images` vs `BskyImages`)
550- Token types generate unit structs with `Display` instead of being skipped
551- Namespace dependency tracking during union generation
552- `generate_cargo_features()` outputs Cargo.toml features with correct deps
553- `sanitize_name()` ensures valid Rust identifiers
554
555**Lexicons** (`jacquard-api`)
556
557Added 646 lexicon schemas. Highlights:
558
559Core ATProto:
560- `com.atproto.*`
561- `com.bad-example.*` for identity resolution
562
563Bluesky:
564- `app.bsky.*` bluesky app
565- `chat.bsky.*` chat client
566- `tools.ozone.*` moderation
567
568Third-party:
569- `sh.tangled.*` - git forge
570- `sh.weaver.*` - orual's WIP markdown blog platform
571- `pub.leaflet.*` - longform publishing
572- `net.anisota.*` - gamified and calming take on bluesky
573- `network.slices.*` - serverless atproto hosting
574- `tools.smokesignal.*` - automation
575- `com.whtwnd.*` - markdown blogging
576- `place.stream.*` - livestreaming
577- `blue.2048.*` - 2048 game
578- `community.lexicon.*` - community extensions (bookmarks, calendar, location, payments)
579- `my.skylights.*` - media tracking
580- `social.psky.*` - social extensions
581- `blue.linkat.*` - link boards
582
583Plus 30+ more experimental/community namespaces.
584
585**Value types** (`jacquard-common`)
586- `RawData` to `Data` conversion with type inference
587- `from_data`, `from_raw_data`, `to_data`, and `to_raw_data` to serialize to and deserialize from the loosely typed value data formats. Particularly useful for second-stage deserialization of type "unknown" fields in lexicons, such as `PostView.record`.
588
589### Changed
590
591- `generate_union()` takes current NSID for dependency tracking
592- Generated code uses `sanitize_name()` for identifiers more consistently
593- Added derive macro for IntoStatic trait implementation
594
595### Fixed
596
597- Methods to extract the output from an XRPC response now behave well with respect to lifetimes and borrowing.
598- Now possible to use jacquard types in places like axum extractors due to lifetime improvements
599- Union variants don't collide when multiple namespaces define similar types and another namespace includes them
