+Sun Mar 6 15:26:11 UTC 2022 - Fred Fu <moonsolo@gmail.com>
+- Update to 8.4:
+  * Command-line Racket provides a new expression editor by default for
+    its read-eval-print loop (REPL). The new REPL is based on the Chez
+    Scheme expression editor, but extended to use the same
+    language-sensitive syntax coloring and indentation tools as DrRacket.
+  * Typed Racket adds a kind system, preventing programmers from
+    writing nonsensical type expressions. It checks whether type
+    constructors are correctly applied to arguments, and separates
+    type constructors from polymorphic types. The `:kind` form enables
+    checking the kind of a type expression at the REPL. The new system
+    also correctly rejects some ill-formed recursive types.
+  * Racket has a `file-or-directory-stat` for unified information about
+    file-system objects.
+  * DrRacket shows the region affected by an `#;` S-expression comment
+    by fading the commented-out region.
+  * Racket on Chez has faster multiplication and division for some
+    numbers.
+  * Web server: The files dispatcher supports all standard caching-related
+    HTTP response headers (e.g., Cache-Control).
+  * Web server: A new dispatcher captures the common pattern of processing
+    HTTP requests and responses in a layered fashion.
+  * The Web Server supports use of the Cache-Control header, and includes
+    a new wrapping dispatcher.
+  * Expander: add "portal" syntax to support new forms of syntax object
+    binding.
+  * Documentation search is improved.
+  * Some hash operations support an optional `try-order?` argument.
+  * The plot-metrics interface has documentation.
+  * Fonts support OpenType feature settings.
+  * The Gui library has improved support for Wayland.
+  * The computation of quadratic roots is further improved.
+  * The `set/c` contract adds support for random generation.
+  * DrRacket's interactions window supports #lang-specific coloring
+    and indentation.
+  * DrRacket's parenthesis-based keyboard shortcuts change based on
+    the parentheses that each different #lang uses.
+  * The release includes many other bug repairs and other improvements!
+
+  Transition/Update notes:
+  * To turn off expeditor and make Racket's REPL go back to the old
+    editline/readline-based editor, use the command
+
+      ,input readline
+
+    and then restart Racket. Get back to the new expression editor with
+
+      ,input expeditor
+
+    To toggle color mode for the new expression editor, use one of the
+    following, which does not require restarting Racket:
+
+      ,color #false
+      ,color #true
+
+  * Support for comment fading in DrRacket requires an increment to
+    the "WXME" format version so files with non-text content written
+    by DrRacket v8.4 will open only in v8.4 and later. This does not
+    affect files that consist only of unicode text.
+  * The addition of the kind system to Typed Racket means that certain
+    mild abuses of the type system no longer type check, most notably
+    the 'application' of a polymorphic type.
+
+- Spec changes:
+  * fix the path to locate a list of html files where references of
+    %{build-root} need to removed
+  * add more html files to the list above
+  * remove the command that deletes `.LOCKpkgs.rktd`, so users will not
+    have to manually create this file as a root user in order to successfully
+    run `raco` or `drracket`.
+
+- RPMlintrc changes:
+  * remove unused filters.
+  * add a filter to ignore warnings on `.LOCKpkgs.rktd`
+
