Jim, I've used the sns extensions for some time now and, from a non-developer perspective, am happy to see the functionality moved into core. I'm sure developers will find it easier to work with, too.
I gave it a try on a test server that had sns, sns_page_hooks, sns_minifier, sns_sass_filter already installed. Here are the steps I took: 1. rake radiant:freeze:edge 2. rake radiant:update 3. rake production db:migrate 4. removed all the sns* extensions with "script/extensions uninstall sns" (for each extension) 5. rake radiant:update 6. rake production db:migrate:extensions 7. started the server and uploaded my css to the new stylesheets page 8. changed the stylesheet tag to read <r:stylesheet slug="main" as="link" media="screen" /> in the layout 9. and for good measure, restarted the server When I open the home page of the test site, the css is not applied. Viewing the page source I see: <link rel="stylesheet" type="text/css" href="/css/main?1280848729" media="screen" /> Typing either "localhost:3000/css/main?1280848729" or "localhost:3000/css/main" in the browser URL field produces the same Page Not Found result. Have I missed some important step? Any ideas? I haven't tried it on a clean, new radiant instance without any other extensions yet. Lastly, will you be adding the ability to minify the css/javascript like sns_minifier? -- marshal
