+Racket v8.15
+
+----------------------------------------------------------------------
+
+- Documentation search results are ordered, with visual cues
+  indicating what their source is (core, main-distribution, etc.).
+  These results are also grouped by language family (Racket, Rhombus,
+  etc.). (See https://docs.racket-lang.org/search/index.html?q=second
+  .)
+- DrRacket offers to restore previously open files when starting,
+  which can be made the default.
+- In DrRacket, Picts can be saved by right-clicking.
+- `raco pkg` introduces the `uninstall` command as the opposite of
+  `install`. The `remove` name for this functionality is retained for
+  compatibility. (See
+  https://docs.racket-lang.org/pkg/cmdline.html#%28part._raco-pkg-uninstall%29
+  .)
+- `raco pkg` improves the handling of `--clone` and `--unclone`. (See
+  https://docs.racket-lang.org/pkg/cmdline.html#%28part._raco-pkg-update%29
+  .)
+- iOS is a compilation target, distinct from macOS.
+- Racket supports falling back to IPv4 during hostname resolution when
+  IPv6 fails.
+- Memory allocated using the ffi/unsafe library can be initially
+  zeroed, using the `'zeroed-atomic` and `'zeroed-atomic-interior`
+  flags. (See
+  https://docs.racket-lang.org/foreign/foreign_pointer-funcs.html#%28idx._%28gentag._11._%28lib._scribblings%2Fforeign%2Fforeign..scrbl%29%29%29
+  .)
