Snyk changed the following file(s):

• package.json
• yarn.lock

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

Breaking upgrade: incompatible CSS plugins with Next.js 12

High Severity

Upgrading next from 10.0.5 to 12.0.8 introduces a breaking change because the project uses deprecated @zeit/next-css and @zeit/next-sass plugins (configured in next.config.js). These plugins are incompatible with Next.js 12's built-in CSS support and will cause build failures with a "Built-in CSS Support Disabled" error. The next.config.js and these dependencies need to be updated to use Next.js's native CSS/Sass support before this upgrade can work.
