• Filter registered Go migrations from the global map with corresponding .go files from the
  filesystem.
  • The code previously assumed all .go migrations would be in the same folder, so this should not
    be a breaking change.
  • See #553 for more details
• Improve output log message for applied up migrations. #562
• Fix an issue where AddMigrationNoTxContext was registering the wrong source because it skipped
  too many frames. #572
• Improve binary version output when using go install.
