+ If Jalview opens a project with links which include $SEQUENCE_ID$ tokens, it will present
+ the user with a warning message, as these links may need to be updated to use $DB_ACCESSION$, if
+ they were added before Jalview 2.10.1. The message lists the links which should be reviewed.
+ The warning can be turned off completely via a checkbox in the message dialog.
