Racket v8.15

posted by Stephen De Gabrielle

We are pleased to announce Racket v8.15 is now available from https://download.racket-lang.org/.

As of this release:

• Documentation search results are ordered, with visual cues indicating what their source is (core, main-distribution, etc.). These results are also grouped by language family (Racket, Rhombus, etc.). Search e.g. second to see an example.

• DrRacket offers to restore previously open files when starting, which can be made the default.

• In DrRacket, Images in editing panels can be saved by right-clicking, including those generated by the functional picture libraries pict and 2htdp/image.

• raco pkg introduces the uninstall command as the opposite of install. The remove name for this functionality is retained for compatibility. (See Package Management in Racket – 3.3 raco pkg uninstall.)

• raco pkg improves the handling of --clone and --unclone. (See Package Management in Racket – 3.2 raco pkg update.)

• iOS is a compilation target, distinct from macOS. (See Inside:Racket C API – 29 Cross-compiling Racket Sources for iOS.)

• Racket supports falling back to IPv4 during hostname resolution when IPv6 fails.

• Memory allocated using the ffi/unsafe library can be initially zeroed, using the 'zeroed-atomic and 'zeroed-atomic-interior flags. (See The Racket Foreign Interface – 4.2 Memory Management malloc mode 'zeroed-atomic and 'zeroed-atomic-interior.)

• Many other bugs are fixed and documentation has been improved!

Thank you
