Google engineers plan to put a short lifespan on cookies delivered via HTTP connections. Chrome engineers want to force developers and advertisers to send cookies via HTTPS. The move won’t stop user tracking on the Internet but will make it more secure.

The capping of HTTP cookies is currently scheduled for Chrome 70, slated to be released in late October 2018, and it won’t visibly affect websites.
