Zoph 0.8pre2 release

I have just posted the second pre-release for v0.8 on Sourceforge: v0.8pre2. It fixes the bugs discovered since v0.8pre1, including the security bug. All users currently running a 0.7.x or 0.8pre1 are advised to update. Users running 0.7.0.x should upgrade to 0.7.0.6 or could consider changing to this release.
