Google are making the changes to improve security and ensure that.js files are not used maliciously.
Hackers have started to use this kind of files to send malware and other potentially unsafe software hidden beneath it.
The company explains that, if you need to send a.js file for legitimate reasons, you can use Google Drive, Google Could Storage, or any other cloud storage platform to do so.
Autopilot update might require a visit to Tesla service center
For now this won't kick in Automatic Emergency Braking, or AEB, so the drivers are still required to act upon this warnings. The only thing that being a Tesla owner will be required for you to is to take your auto to the Tesla technicians.
When users upload a file that is banned in Gmail, they will be warned that the attachment is blocked for security reasons. Google also blocks archives whose listed file content is password protected or whose content includes a password protected archive.
It's unclear Google will also show a warning when users receive emails with JS files attached. This move by Google should prevent at least some instances of that happening, so this is a case of Google protecting Gmail users from themselves.
