Just to inform you: redex x-spacing and y-spacing keyword parameters are in redex/private/traces.ss but not in the contracts of
redex/gui.ss.

Subject: [plt-dev] Release Announcement for v4.2.1
The release announcement item candidates that I have so far are below.
Please mail me new items and/or edits.
----------------------------------------------------------------------
[Matthew]
* fixed problem with installation of docs in planet packages
(adjust planet client to handle nested planet invocations by
re-building the doc index only once)
* delete/backspace issue in DrScheme/MrEd
* identifier-prune-lexical-context (4.2.0.2)
syntax-local-lift-values-expression (4.2.0.3)
syntax-local-lift-provide
* safe-for-space fixes for the interepreter
* expose and support unreadable symbols
* Various efficiency improvements to keyword arguments.
* better interaction of HtDP languages with scheme/match
[Jay]
* FrTime reorganization
[Matthias]
* new universe teachpack updates?
(universe keeps track of iworlds now; utest contains ball game)
[Robby]
* redex stuff (brought back syntax locations (for better error
messages) in redex main forms and improved define-relation;
improved where patterns and a few bug fixes; added
metafunction-cases and fixed a layout bug; fixed bug in
rendering of reduction relations; added x-spacing and y-spacing
parameters to traces and traces/ps)
* DrScheme's module browser always shows files from the same
collection (possibly a planet collection) regardless of the kind
of `require' form that is used.
[Ryan]
* macro-debugger stuff (disable lift errors; fixed opaque variable
ref bug)
* syntax/parse and syntax/id-table libraries
[Sam]
* typed-scheme stuff ("paths branch")
[Eli]
* New `make-at-reader/inside' and `make-at-reader' makes it easy
to define new scribble readers (in "inside mode" or not) with a
command character different from `@'.
* Note about one of the last builds to include a solaris
distribution, and if anyone has access to a solaris machine we
can incorporate it into the build.
