Memcached 1.5.13 Release Notes

Date: 2019-4-15



Experimental TLS support. Brought to you by Netflix, thanks! :)

See memcached --help for usage. Allows mixing TLS and non-TLS listeners (for local monitoring, tests, etc). Has been reviewed and tested but please treat it as experimental. Let us know if you run into any issues!

Requires a minimum OpenSSL version of 1.1.0. OpenSSL's API changed the API, deprecating some old functions. They also redid the locking code entirely, which scales much better. Old versions should be avoided for security reasons, as well as for not giving good performance in multithreaded servers such as memcached.

See doc/tls.txt for more information.

As of this writing no known memcached clients support TLS; please contact the maintainers/authors of your client software to enquire about adding TLS support. You can also use proxies, routers, and so on.

If you have extremely sensitive performance requirements, take care in deploying this feature.


  • Basic implementation of TLS for memcached.
  • Improve Get And Touch documentation
