Release Announcement for v7.3

[John Clements]

The release announcement sketch that I have so far is below. Please
mail me new items and/or edits.

Editor’s note: This is my first time scraping the commit logs, so *please* don’t
be offended by my failure to notice your awesome and dramatic improvement,
and in return I promise not to be offended when you tell me that my text completely
misses the point of your commit :).

Please phrase announcements using complete sentences and avoid the
word "now".

Racket-on-Chez continues to improve. Snapshot builds are currently
available at pre.racket-lang.org, and we expect that Racket-on-Chez
will be included as a download option in the next release.

The I/O work was all part of Racket-on-Chez, so I think we skip this
one.


How about a bullet on space-efficient contracts (commit a0fdee59)?

I don't think this should be in the notes, since we didn't actually
get anything from non-working to working for this release.

I see; I’ll take it out.
