14.5.3 Other Changes

• library(clpfd): minor efficiency issues.
• The user_error stream is always unbuffered, even when not attached to a terminal.
• Improved detection of the ‘executable’ file property under Windows, e.g. in absolute_file_name/3 and process_create/[2,3].
• The Prolog flag title is now saved by set_prolog_flag(title, …) on all platforms. It used to be ignored except under Windows.
