+[v2.4.0][] - 2021-03-27
+-----------------------
+
+### Changes
+
+- Add support for `touchf()`, formatted string support for `touch()`
+- Add support for `erasef()`, formatted string support for `erase()`
+- Add support for `strtrim()`, trims leading and trailing white-space
+  from a string
+
+### Fixes
+
+- Fix `systemf()` improper handling of `system()` return value.  Now
+  checks if exited OK, then returning the exit status of the command, or
+  if not exited OK, then checks if the command was signaled, and returns
+  -1 with `errno` set.  This also allows for returning 127, like
+  `system()`, if the shell, or the program itself, did not exist
