Voltz is reverting to 2.0.4 for recommended build

The Voltz 3.1.1 recommended build release brought to light several issues. After consulting with the Calclavia/Voltz dev team and performing extensive troubleshooting, it's been determined that no fixes will be available for any of these issues for an extended time period.
Considering this, and the Calclavia/Voltz dev team's acknowledgement that griefing will be a serious problem (even with Worldguard protections), we have no choice but to revert to 2.0.4 as the recommended build.
Build 3.1.1 will CONTINUE to be available as a development/beta build in the launcher, and will be re-promoted to recommended as soon as fixes are available.
Sorry for the inconvenience! 


Important Voltz 3.1.1 update information. Please read!

Voltz 3.1.1 has a bug involving grief protection on SMP servers.  The impact on single-player experience should be minimal.

We are maintaining 3.1.1 as the recommended build for the time being, until it's clear whether a timely fix will become available; if not, we'll be rolling the recommended build back to 2.0.4.  

In the meantime you can manually select 2.0.4 by selecting the small gear under the Voltz modpack icon, choose "Manually select a build", and pick 2.0.4 from the drop down menu as illustrated below:

Voltz 3.1.1 is being promoted to RECOMMENDED build today!

The newest update for Voltz, 3.1.1, will be promoted to RECOMMENDED shortly.
Sadly, this is almost certainly going to necessitate a COMPLETE WIPE of your existing Voltz worlds!  TAKE BACKUPS BEFORE YOU UPGRADE!
Calclavia has provided a new list of mods to include in this Voltz release.  Please note that Mekanism has been removed from the pack.  However, many mods have been added and updated:  Buildcraft, Extra Utilities, Forestry, Galacticraft, Mad Science, OpenComponents, Open Computers, Project Red, Railcraft, and Thermal Expansion (among others.)  Also, the existing Calclavia mods have seen many exciting changes!
Please note there is a hard Java 7 requirement on this pack.  If you get an error NoClassDefFoundError: java/lang/ReflectiveOperationException then you're not running Java 7.
See this Technic post for information on how to upgrade to Java 7.
The server is available here.
For a complete list of mods, view the announcement in the Voltz forum here.
There is NO UPGRADE PATH from previous versions!  Don't expect to import your existing worlds, MAKE BACKUPS BEFORE YOU DEPLOY THIS NEW VERSION.

Minecraft 1.7.9 and 1.7.10 Now Available For Modpack Creation

This is just a heads-up, since we've taken so long to get around to it.  The platform, launcher, and solder should now support Minecraft 1.7.9 and 1.7.10 packs.  No action is required on your behalf, those Minecraft versions should appear anywhere Minecraft versions are selected.  Due to a sorting issue, 1.7.10 will not show up near the top, but further down the list.  We're investigating this issue currently.  Have fun!
