From d939de17df08b7a2ff8302869981f4fc88566cd9 Mon Sep 17 00:00:00 2001 From: Sheogorath Date: Fri, 30 Mar 2018 16:33:32 +0200 Subject: Fix CSP for disqus and Google Analytics This commit should fix existing problems with Disqus and Google Analytics enabled in the meta-yaml section of a note. Before this commit they were blocked by the strict CSP. It's still possible to disable the added directives using `addDisqus` and `addGoogleAnalytics` in the `csp` config section. They are enabled by default to prevent breaking changes.
