+             the main menu (they remain in the Write-Out and Insert
+             menus, respectively), is more precise in what it accepts as
+             a rebindable key name, ignores any presses of <Esc> before
+             a valid command keystroke, recognizes some more escape
+             sequences for modified editing-pad keys, does not hide

+2018.06.02 - GNU nano 2.9.8 "Espresso" brings the ability to filter the
+             buffer (or the marked region) through an external command
+             (^R^X and prefix the command with the pipe symbol, "|"), is
+             better at detecting and maintaining paragraphs, is able to
+             justify //-style comments, fixes a crash when the binding
+             of a key to a string lacks a closing quote, gives feedback
+             about the number of lines written also when prepending or
+             appending, and fixes a couple of bugs with the linter.
+
+2018.05.15 - GNU nano 2.9.7 "Hvide Sande" adds the option '--afterends'
+             for making Ctrl+Right (the nextword function) stop at word
+             ends instead of beginnings, accepts multibyte letters for
+             the Yes/No/All answers, does emergency saves of changed
+             buffers in the unlikely event that nano crashes, adds the
+             until-now missing bindable function 'linenumbers', and
+             renames the toggles 'constupdate' to 'constantshow' and
+             'cuttoend' to 'cutfromcursor', for consistency with the
+             corresponding options -- adjust your nanorc files soon.
+
+2018.04.27 - GNU nano 2.9.6 "Gomance" fixes a crash in word completion,
+             makes --enable-altrcname work again, improves the fluidity
+             of scrolling when using the touchpad, tweaks the syntaxes
+             for shell scripts and PO files, makes a replacing session
+             go always forward by default, no longer inserts a newline
+             after an external spell check of a selected region, always
+             accepts the English Y and N (and A) at a yes-no prompt in
+             any locale, and solves a few hypothetical bugs.
+
 2018.03.29 - GNU nano 2.9.5 "Kiša pada" changes the way the Scroll-Up
              and Scroll-Down commands work (M-- and M-+): instead of
              keeping the cursor in the same screen position they now

The original 'tip' program &quot;establishes a full duplex terminal connection to a remote host&quot;, and was included with many older Unix systems (and newer ones like Solaris).
