If your cert is about to expire in less than 30 days, check the logs under `/config/log/letsencrypt` to see why the renewals have been failing. It is recommended to input your e-mail in docker parameters so you receive expiration notices from Let's Encrypt in those circumstances.
 ### Security and password protection
 * The container detects changes to url and subdomains, revokes existing certs and generates new ones during start.
-* The container provides a pre-generated 4096-bit dhparams.pem (rotated weekly via [Jenkins job](https://ci.linuxserver.io/blue/organizations/jenkins/Xtras-Builders-Etc%2Fdhparams-uploader/activity)) for new instances, however you may generate your own by running `docker exec swag openssl dhparam -out /config/nginx/dhparams.pem 4096` WARNING: This takes a very long time
+* Per [RFC7919](https://datatracker.ietf.org/doc/html/rfc7919), the container is shipping [ffdhe4096](https://ssl-config.mozilla.org/ffdhe4096.txt) as the `dhparams.pem`.
 * If you'd like to password protect your sites, you can use htpasswd. Run the following command on your host to generate the htpasswd file `docker exec -it swag htpasswd -c /config/nginx/.htpasswd <username>`
 * You can add multiple user:pass to `.htpasswd`. For the first user, use the above command, for others, use the above command without the `-c` flag, as it will force deletion of the existing `.htpasswd` and creation of a new one
 * You can also use ldap auth for security and access control. A sample, user configurable ldap.conf is provided, and it requires the separate image [linuxserver/ldap-auth](https://hub.docker.com/r/linuxserver/ldap-auth/) to communicate with an ldap server.

 ## Versions
 
-* **27.04.21:** - [Existing users should update:](https://github.com/linuxserver/docker-swag/blob/master/README.md#updating-configs) nginx.conf, ssl.conf, proxy.conf, and the default site-conf - Rework nginx.conf to be inline with alpine upstream and relocate lines from other files.
+* **14.05.21:** - [Existing users should update:](https://github.com/linuxserver/docker-swag/blob/master/README.md#updating-configs) nginx.conf, ssl.conf, proxy.conf, and the default site-conf - Rework nginx.conf to be inline with alpine upstream and relocate lines from other files. Use linuxserver.io wheel index for pip packages. Switch to using [ffdhe4096](https://ssl-config.mozilla.org/ffdhe4096.txt) for `dhparams.pem` per [RFC7919](https://datatracker.ietf.org/doc/html/rfc7919). Added `worker_processes.conf`, which sets the number of nginx workers, and `resolver.conf`, which sets the dns resolver. Both conf files are auto-generated only on first start and can be user modified later.
 * **21.04.21:** - [Existing users should update:](https://github.com/linuxserver/docker-swag/blob/master/README.md#updating-configs) authelia-server.conf and authelia-location.conf - Add remote name/email headers and pass http method.
 * **12.04.21:** - Add php7-gmp and php7-pecl-mailparse.
 * **12.04.21:** - Add support for vultr dns validation.
