Racket v8.5
Racket version 8.5 is now available from
https://racket-lang.org/
As of this release:
* Racket's new `-y` flag automatically keeps compiled files up to date,
reducing subsequent load times.
* Error-message realms allow Racket-hosted languages to adapt and
rewrite error messages to make sense in a particular context.
* Nonprivileged users can control package installation scope using an
"other-version" directory in the addon-dir.
* Racket CS runs on platforms where native-code generation is not
currently supported (e.g., s390x or ppc64). See "README.txt" in the
source distribution for more information on the --enable-pb flag to
configure.
* DrRacket's new 'Reopen Closed Tab' file menu item will open previously
closed tabs.
* Typed Racket has support for the `xml` library; use `typed/xml`.
* Rackunit reports source locations for failed test cases in the
Typed Racket language.
* Plot has violin plots and improved box-and-whisker plots.
* Boxes are supported alongside lists, vectors etc. in place-channel
messages.
* Those who manually configure Racket CS to use Zlib compression for
compiled code should be aware of CVE-2018-25032; the next release and
the current snapshot builds use a newer, safer version of zlib.
* The release includes many other repairs and changes!
