In Roku SDK (software documentation kit), http://sdkdocs.roku.com/ - from time to time i remember to check "list of recently updated pages". That's the only way to keep in touch with new developments, since release notes are not regularly or reliably updated.
Today i looked at it and it shows "Sep 08, 2014" as last update date. But i know there have been more recent updates too. I suspect that some process that periodically updates Confluence journal might have gone down or underlying SQL DB might have gone wonky, endangering the integrity of the wiki.
