+1. Changes to Bash

+a. Tilde expansion isn't performed on indexed array subscripts, even for
+   backwards compatibility.
+
+b. The shell doesn't exit in posix mode if the eval builtin gets a parse
+   error when run by the command builtin.
+
+c. Fixed a bug that caused a shell comment in an alias to not find the end
+   of the alias properly.
+
+d. Reverted a change from April, 2018 that caused strings containing
+   backslashes to be flagged as glob patterns.
+
+2. Changes to Readline

+3. New Features in Bash
