IDA pro and Hex-Rays decompiler version question

[jonwil]

I am currently using HexRays x86 1.5.110408 along with IDA 6.1.110315 and I see all sorts of reports about various leaks of newer versions of all sorts of IDA related things without really understanding it all.
Can anyone tell me:
1.If there are any working newer leaked versions of HexRays x86 than the one I have (and if so what to plug into Google or the exetools search box to find them)
2.Which version of IDA is the newest leaked version that will work properly with the aforementioned HexRays x86 version (either the one I have now or if there is a newer one, that newer one) and what search term do I need to use to find it? (assuming my current version of IDA is not the newest one that will work with my version of HexRays)
and 3.I see reports of a leaked version of HexRays ARM. Is this true, does the leaked version work and (if it does work) what search term do I need to use to find it (and the version of IDA I need to use alongside it)

Its confusing with so many posts, some of which talk about leaked IDA versions (all the way from 5.x on up), some of which talk about leaked HexRays versions, some of which talk about versions that have been "leaked" into the underground but not made public, others talking about hacked trial/demo/limited versions and still others that talk about what HexRays has released without actually talking about things leaked into the scene yet.
