ASCII export: Better link export.
Links with description not create a note before the next headline that contains the link. In the text, the description will be shown. The new variable `org-export-ascii-links-to-notes' can be configured to turn off this behavior, then the reference will be inserted inline in the text. If the line becomes too long because of this, it will be wrapped.
