• The major version of the module is now included at the end of the module
  path. Previously, it was not possible to import the module in projects that
  were using Go modules. Reported by Roman Glushko. GitHub #81.
• The minimum Go version is now 1.13.
• A valid account ID and license key combination is now required for database
  downloads, so those configuration options are now required.
• The error handling when closing a local database file would previously
  ignore errors and, upon upgrading to github.com/pkg/errors 0.9.0,
  would fail to ignore expected errors. Reported by Ilya Skrypitsa and
  pgnd. GitHub #69 and #70.
• The RPM release was previously lacking the correct owner and group on files
  and directories. Among other things, this caused the package to conflict with
  the GeoIP package in CentOS 7 and GeoIP-GeoLite-data in CentOS 8. The
  files are now owned by root. Reported by neonknight. GitHub #76.
