![Fishsay Racket 9.2](https://global.discourse-cdn.com/free1/uploads/racket/original/2X/0/0e52c062a0b735f36cf3897d74fc862901f3b20b.png) We are pleased to announce Racket v9.2 is now available from [https://download.racket-lang.org/](https://download.racket-lang.org). ## As of this release: - The [`match`](https://docs.racket-lang.org/reference/match.html#%28form._%28%28lib._racket%2Fmatch..rkt%29._match%29%29) form checks that when non-linear patterns (patterns where the same variable is used multiple times) are used with `...`, the two parts of the matched value actually are equal. Additionally, match rejects non-linear patterns where one use of the variable is used with `...` and another is not. [This repair could cause existing code to fail](https://github.com/racket/racket/pull/5467). - Typed Racket's types for the `asin` and `acos` procedures correctly handle situations where the function produces a complex number, avoiding unsound results that were previously possible. [This repair could cause existing code to fail at compile time](https://github.com/racket/typed-racket/pull/1428). - The [`#%foreign-inline`](https://docs.racket-lang.org/reference/foreign-inline.html#%28form._%28%28quote._~23~25kernel%29._~23~25foreign-inline%29%29) core syntactic form provides unsafe access to facilities provided at the linklet layer by a Racket implementation. This means that any code that handles all core forms by enumeration will need to be updated. - Racket 9.2 uses Unicode 17.0 for character and string operations. - This release includes internal support for a more static "ffi2" foreign interface (to be used in a future package). - The [`terminal-file-position`](https://docs.racket-lang.org/reference/port-buffers.html#%28def._%28%28quote._~23~25kernel%29._terminal-file-position%29%29) function counts bytes written to ports connected to a terminal, such as `stdin` and `stderr`. - Cross-phase persistent modules allow more types of `quote`d data. - The implementations of `member`, `memw`, `when`, `unless`, `let/ec`, and `cond` are rewritten to use only [`racket/kernel`](https://docs.racket-lang.org/reference/Kernel_Forms_and_Functions.html) syntax - The [`impersonator-property-predicate-procedure?`](https://docs.racket-lang.org/reference/chaperones.html#%28def._%28%28quote._~23~25kernel%29._impersonator-property-predicate-procedure~3f%29%29) function identifies procedures created by `make-impersonator-property`. - In Typed Racket, polymorphic struct types are printed using type arguments (e.g., `(Array Byte)`) rather than exposing an internal representation. - The stepper's display of numbers better matches the language settings. - Scribble documents that do not use the Racket-manual style get an [`initial-scale`](https://docs.racket-lang.org/scribble/core.html#%28def._%28%28lib._scribble%2Fhtml-properties..rkt%29._initial-scale%29%29) of 1.0, instead of the manual style's 0.8, but this can be configured using the `initial-scale` property. - By default, margin notes appear inline for narrow displays in all styles, not just in the Racket-manual style. - Big-bang programs distributed as .dmg files correctly handle the `close-on-stop` feature. - There are many other repairs and documentation improvements!
