|
|
- Add `typed/racket/os` and `typed/racket/db{/sqlite3}`.
|
|
6.6
|
|
- Warn on opaque values passed to `any-wrap/c`. This will become an
|
|
error in the future.
|
|
- Added intersection types.
|
|
- Add typed/syntax/{modread,srcloc,readerr}
|
|
- Improve type & contract serialization and avoid pconvert.
|
|
- Check source type in `cast` (potential incompatibility)
|
|
- Internal: rename "filter" to "prop"
|
|
6.5
|
|
- Added `simple-result->` to improve generated contract performance.
|
|
- Improve error message printing.
|
|
- Add `typed/racket/random`.
|
|
- Internal: populate type table unconditionally, for use in tooltips.
|
|
6.4
|
|
- Contract performance improvements, including generating code that
|
|
the contract system can optimize
|
|
- Make `any-wrap/c` more permissive on opaque structs.
|
|
- Soundly check opaque predicates.
|
|
- Add `#:type-name` option to `struct`.
|
|
6.3
|
|
- Startup time reduction
|
|
- Tightening and cleanup of numeric types
|
|
- Sealing contracts for row polymorphic types
|
|
- `define-new-subtype`
|
|
- More robust compound pair operations optimizations
|
|
- Redesign of top-level support, using trampolining macros
|
|
- Static contract caching more conservative, causes contract generation slowdowns
|
|
- Experimental unit support
|
|
- `typed/racket/unsafe`, with `unsafe-require/typed` and `unsafe-provide`
|
|
6.2
|
|
- Use submodules to avoid allocating contract wrappers when not needed.
|
|
- Class types and contract generation are significantly improved, but still experimental.
|
|
- Many types for GUI classes added.
|
|
- Tests on let-bound variables now refine the type of what was bound to them.
|
|
- DrRacket tooltips for types and type errors.
|
|
- Support for prefab structs.
|
|
- Types for a variety of libraries, including `rackunit` and `json`.
|
|
6.1.1
|
|
- Exception handling is now sound. Broke existing programs (e.g. marketplace).
|
|
- More types for GUI and framework.
|
|
- Support for casts and predicates in typed regions.
|
|
6.1
|
|
- Inference speedups.
|
|
- Support for contracted functions in the base environment.
|
|

|
|
6.0.1
|
|
- Types for classes (including row types, sealing contracts, etc).
|
|
Still experimental.
|
|
- Contracts are now optimized; in particular, redundant contracts are omitted
|
|
- Filters work with conditions that raise errors, as in the pattern
|
|
(begin (unless (number? x) (error 'fail))
|
|
(add1 x))
|
|
- Types are now pretty-printed
|
|
- Add prefix-style function types and `->*` function type constructor
|
|
- Support syntactic forms without : (such as let, lambda, for, etc)
|
|
- Type aliases support arbitrary mutual recursion
|
|
- Inform check-syntax about expansion results
|
|
- Add `typed/untyped-utils` library
