------------------------
+---------------------
-
-### Fixes
-- Fix #38: Fix for multiline representing as one line
-- Fix packaging, missing files in libeditline1, regression from 1.16.0
-- Fix packaging, update to latest std version
-- Fix formatting of function names in man page
-- Restore tar.gz distribution, for usability on systems that do not
-  have xz in their default install
-
-
-[1.17.0][] - 2020-01-05
------------------------
-
-### Changes
-- Simple multi-line support by Dima Volynets, @dvolynets
-
-### Fixes
-- Fix return value from `read_history()` and `write_history()`, could
-  return `errno` instead of `EOF` to indicate error.  Now both functions
-  have uniform return values on error
-- Handle internal `realloc()` errors better.  Now memory is not leaked
-  if `realloc()` fails
-- Fix possible NULL pointer dereference in key binding lookup function
