See changelog in README.md - several useful features/fixes; one change that could break your install if using custom-coded donation forms (i.e. forms not created through CiviContribute).

Remember to download the release files not the source code! i.e. pick one of:

• uk.artfulrobot.civicrm.gocardless-1.8.tgz
• uk.artfulrobot.civicrm.gocardless-1.8.zip

below.
