Log Message:
lang/racket{,-textual}: update to 8.11.1

8.11.1:

    This bug-fix release repairs a problem with building from source when using \ 
the “builtpkgs” source distribution.

8.11:

    Match clauses can include a #:do option to allow evaluation of code and \ 
bindings before a following #:when clause. See match.

    JSON Serialization supports indentation with an #:indent option to \ 
write-json. See write-json.

    An initiate-sequence function simplifies the creation of sequences. See \ 
initiate-sequence.

    The :do-in form allows an inner definition sequence. See :do-in.

    The redex-define form allows pattern-matching in PLT Redex using a \ 
define-like syntax. See redex-define.

    Racket and Chez Scheme use Robert L. Smith’s “Algorithm 116” for \ 
division of complex numbers. See Robert L. Smith. 1962. Algorithm 116: Complex \ 
division. Commun. ACM 5, 8 (Aug. 1962), 435. \ 
https://dl.acm.org/doi/10.1145/368637.368661.

    DrRacket has indentation guides that provide visual cues indicating how code \ 
is indented and grouped, accessible by using (<menu-key>-shift-i). See \ 
text:indent-guides<%>.

    “Comment-out” menu items can be specific to the #lang used by the \ 
current file. See Comments.

    Unused identifiers have a tooltip indicating that they have no bound occurrences.

    Quickscript includes a new form of scripting in the form of “hook” \ 
functions that can be attached to existing events. See Hooks.

    Plots include plot-inset and plot-legend-padding parameters to control the \ 
amount of space left unused around the plot edge and plot legend. See \ 
plot-inset.

    There are many other documentation improvements, optimizations, and bug fixes!
