Juanjo or someone else can confirm/deny/tell details but I remember some newer features are not available in LW11 with Octane
But in general, LW is one of the rare products that always is recommended to upgrade or update, it never fails to be pleasant

At least for me new features in LW2015 alone were huge benefit and there are always a long list of improvements. And one very important thing is that with LW2015 there is new PDF manual so no need to browse through numerous 'addendums' anymore
And there is Siggraph sale 10-17 Aug (don't know if that applies to upgrades though) so go for it fast!
