+You are likely using a very old version of Termux,
+probably installed from the Google Play Store.
+There are plans in the near future to remove the
+Termux apps from the Play Store so that new users
+cannot install them and to **disable** them for
+existing users with updates so that they do not
+continue using outdated versions. Instead, you
+are encouraged to move to F-Droid or Github sources
+(see [1]). You can backup all your current Termux
+data before uninstallation and then restore it later
+by following instructions in the wiki [2]. Check
+the changelog [3] for all the new features and fixes
+that you are currently missing. Check [4] for why
+this is being done.
