Below are the minimum changes required to get the underlying AS7 config file in TorqueBox 2.0.3 to work with TorqueBox 2.1.0. There's one diff for non-clustered environments (standalone.xml) and another for clustered environments (standalone-ha.xml).
If you are clustering without multicast, then you'll also need to add the attribute advertise='false' to the `` element in standalone-ha.xml in addition to the changes below.

| # Monkey patch to Sprockets::StaticCompiler, a class provided by actionpack | |
| # that's used by the assets:precompile task. This patch uses the Parallel gem | |
| # to parallelize asset compilation in the simplest way possible. | |
| # | |
| # Parallel wraps Process.fork to handle things like inter-process communication | |
| # via pipes and determining the maximum number of processes to run based on | |
| # your system's total logical processors. So far only tested on MRI 1.9.3 on OS X. | |
