+### Nginx
+
+We introduced some new parameters in our Nginx config:
+- Internet Protocol version 6 ([IPv6](https://en.wikipedia.org/wiki/IPv6)) support
+- TLS generation, see [the recent tutorial](https://blog.cryptpad.org/2022/12/12/tutorial-nginx-tls-acme/) on our blog
+- Better [TLS sessions](https://vincent.bernat.ch/en/blog/2011-ssl-session-reuse-rfc5077),  handling timeout, tickets & longer cache
+- Longer [HTTP Strict Transport Security](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) (HSTS), now 2 years
+- [Online Certificate Status Protocol](https://en.wikipedia.org/wiki/OCSP_stapling) (OCSP) stapling support
