[John Clements]

Here’s the proposed release announcement. Let me know of things that are missing!

----------------------------------------------------------------------
Racket version 8.3 is now available from

* Racket removes syntax arming and disarming in favor of a simpler
system of protected syntax operations, along with other updates to the
syntax system.

* DrRacket has improved support for custom #lang languages.

* Typed Racket improves precision for type-checking of non-polymorphic
structures, existential types, and certain binding forms.

* Scribble HTML output gains a button to show / hide the table of
contents on mobile platforms.

* Redex's stepper's GUI shows IO-judgment form rule names.

* Many bug fixes!

Hi John,

regarding my contribution:

https://github.com/racket/racket/pull/3950

I explicitly wrote:

Originally found and preliminary investigation of the issue: Dominik
Pantůček

Further investigation and proposed patch: Adam Zaiter
adam....@trustica.cz (as a part of his work on this project)

If it is possible, I would definitely like to give credit where credit
is due and have Adam in the list as well.


Cheers,
Dominik

I’m happy to add Adam Zaiter to the list of contributors. Many thanks!

John
