Racket v7.7
Racket version 7.7 is now available from
https://racket-lang.org/
* Racket CS remains ready for production use---thanks to those who have
been putting it into practice to help iron out the remaining
kinks---and it now supports a C API for embedding into other
applications. See the "Inside: Racket" documentation for details.
* Racket CS uses a new HAMT implementation, dramatically reducing the memory
required for immutable hash tables.
* Optimizations to the Racket CS compiler result in a code size savings
of approximately 20%.
* GC callbacks are reliably called on major collections in Racket CS.
Also, Garbage collection is 10-20% faster.
* DrRacket can recover much more quickly from errors involving large
stack traces.
* DrRacket now supports the use of the keyboard in the Mac OS Catalina
"Open File" dialog.
* The net/http-client collection supports the `deflate` content encoding.
* The `call-in-continuation` function (like Marc Feeley's
`continuation-graft`) simplifies certain `call/cc` patterns by
calling a thunk in a restored continuation.
* Call-with-current-language allows more reliable tests for language
level code.
* Use of the Cairo library can be multi-threaded.
* Improved documentation!
* Many bug fixes!
