Mans probably knows more.
There is no benefit to v8. v7 added support for the rarely/never used arithmetic coding option, left out of earlier versions due to patent issues. Since nobody uses this mode, supporting it is irrelevant. v8 only adds some experimental, non-standard coding options even less relevant to any real-world uses. What is relevant is, however, that v8 is significantly slower than v6 in the default configuration. I don't remember if this slowdown was present already in v7. > At any rate, -turbo as an upstream is the only sane decision.
