 ## Versions
 
+* **09.02.21:** - Rebasing to alpine 3.13. Add nginx mods brotli and dav-ext. Remove nginx mods lua and lua-upstream (due to regression over the last couple of years).
 * **26.01.21:** - Add support for hetzner dns validation.
 * **20.01.21:** - Add check for ZeroSSL EAB retrieval.
 * **08.01.21:** - 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.
