I’m sure most of you have already heard, or were already aware (months ago), that SharePoint 2010 Mainstream support is ending soon.
Stefan posted it on his technet blog yesterday and here’s a link in case you missed it. http://blogs.technet.com/b/stefan_gossner/archive/2015/07/16/still-on-sharepoint-2010.aspx

Many of us who were running critical apps on SharePoint 2007, (or heaven’s no, SharePoint 2003) already know what this means.
But in case you don’t, here is a chart taken from the Microsoft Support Lifecycle page that explains the differences between the type of support available in these phases as well as other questions you may have. https://support.microsoft.com/en-us/lifecycle?p1=14944#gp/lifePolicy

And no, this doesn’t mean your SharePoint 2010 farms are going to burst into balls of virtual flames on Oct 14th, 2015. (Although if that does happen to you, DM me a picture!)
