v3.4.0

  • Makes get run much faster when some time passes between calling load() and get(). See the JavaScript agent preloading guide to learn how to leverage it.
  • Added an error constant for bad server response format: FingerprintJS.ERROR_BAD_RESPONSE_FORMAT. The error can be caused by wrong endpoint.
  • The disableTls option is moved from the get options to the load options. It still works when set within get options for compatibility, but doesn't actually disable the TLS request. So we recommend updating your code if you use disableTls.
