Due to our licensing changes with Coherence, we must remove it from our non clustered editions of Confluence (now referred to as 'Standard' edition). Ehcache will now be replacing Confluence's caching layer for Standard editions of Confluence. To accommodate for this change, a new 3.0 version of Confluence will be released and available to customers with non clustered licenses. For more details see: http://confluence.atlassian.com/x/YIHZCw
