My error log is being filled up every day with instances of the following warnings

> [PrettyText] Deprecation notice: `whiteList` has been replaced with `allowList` [deprecated since Discourse 2.6.0.beta.4] [removal in Discourse 2.7.0] [deprecation id: discourse.markdown-it.whitelist]

> Deprecation notice: `SiteSetting.enable_personal_messages` has been deprecated. Please use `SiteSetting.personal_message_enabled_groups` instead. (removal in Discourse 3.0) At /var/www/discourse/lib/

> Deprecation notice: `SiteSetting.secure_media` has been deprecated. Please use `SiteSetting.secure_uploads` instead. (removal in Discourse 3.0) At /var/www/discourse/lib/site\_setting\_extension.rb:199

How do I prevent these errors from recurring?

My forum [https://nzarchitecture.net.nz](https://nzarchitecture.net.nz) is running under Discourse 3.1.0.beta2
