For internal TCP/UDP load balancers, you can create multiple forwarding rules with the same IP address. The forwarding rules can have different protocols and ports. This feature is available in Beta.

April 27, 2020

Google-managed SSL certificates are available in General Availability.

April 23, 2020

External HTTP(S) load balancers now support header-based routing and query parameter-based routing.

External HTTP(S) load balancers now support URL rewrites and redirects.

URL rewrites allow you to decouple the URLs that your external users use from those that your services use.

With URL redirects, you can redirect client requests from one URL to another URL.

These features are available in General Availability.

April 10, 2020

Backend services documentation is updated through the Cloud Load Balancing doc set.

April 09, 2020

TLS v1.3 is now enabled by default for all external HTTPS load balancers, SSL proxy load balancers, and Cloud CDN. Note that this change doesn't apply to internal HTTPS load balancers or Traffic Director.

TLS v1.3 supports modern ciphers with forward-secrecy as a baseline and, critically, reduces the number of round trips required to establish a TLS session, which directly improves performance seen by your end-users.

Clients that support TLS v1.3 include Chrome, Chromium-based browsers, and Android. These clients automatically negotiate TLS v1.3 without requiring any changes. Clients that do not support TLS v1.3 are unaffected.
