• The match 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.
• 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.
• The #%foreign-inline 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.
• Unicode 17.0 is used 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 function counts bytes written to ports
  connected to a terminal, such as stdin and stderr.
• Cross-phase persistent modules allow more types of quoted data.
• The implementations of member, memw, when, unless, let/ec,
  and cond are rewritten to use only racket/kernel syntax
• The impersonator-property-predicate-procedure? 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 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!
