 # changelog
 changelogs:
+  - { date: "23.01.21:", desc: "Rebasing to alpine 3.13." }
   - { date: "20.01.21:", desc: "Add check for ZeroSSL EAB retrieval." }
   - { date: "08.01.21:", desc: "Add support for getting certs from [ZeroSSL](https://zerossl.com/) via optional `CERTPROVIDER` env var. Update aliyun, domeneshop, inxw and transip dns plugins with the new plugin names. Hide `donoteditthisfile.conf` because users were editing it despite its name. Suppress harmless error when no proxy confs are enabled." }
   - { date: "03.01.21:", desc: "[Existing users should update:](https://github.com/linuxserver/docker-swag/blob/master/README.md#updating-configs) /config/nginx/site-confs/default - Add helper pages to aid troubleshooting" }
