Highlights for software developers include a new internal testing framework for the RM API and tight integration with IntelliJ IDEA if you use that IDE.
Highlights for software developers include a new internal testing
framework for the RM API, tight integration with IntelliJ IDEA if
you use that IDE, a propagate-only mode (no VMM required), a way to
quickly overwrite just jar files in an installation, and better
tarball/release management.

The autoconfigure process is now an option of nimbus-configure (<b>New in RC2</b>).

<p>
See the installation guide for details. The autoconfigure process
is also now more in line with the installation guide: it does less
so that it fits better in the guide's step by step instructions.

The build system now forces the Java pieces to be 1.5
compatible. (<b>New in RC2</b>)

<li>
<p>
<i>scripts/check-jars.sh</i> makes it easy to check 1.5
compatibility on any directory of jars (including
subdirectories). For example, a Nimbus installation.

Lets you change Java source code and just build and install
the jars and get the changes straight into an existing
installation for more immediate non-automated testing.

<p><i>Propagate-only mode</i> (<b>New in RC2</b>)</p>
<p>
New propagation-only mode for workspace-control that helps
with development and testing of fast/smart propagation
techniques. Does not require libvirt or any sudo
privileges to work with the central Nimbus service and
fully exercise propagation.

<p>
See the embedded notes in the new 'src/propagate-only.sh'
script in workspace-control.

The new, default repository behavior is triggered when "vws.repository.type=cumulus" is present in the cloud.properties file. This is a value that any Nimbus 2.5+ cloud should distribute in their cloud.properties file (start with the <a href="admin/z2c/index.html">Zero To Cloud Guide</a> to learn how to give out the right cloud.properties file).

Added support for using unencrypted keys directly instead of
needing to run proxy-init. (<b>New in RC2</b>)
</p>
<p>
The properties 'nimbus.cert' and 'nimbus.key' are consulted
first, then normal a grid proxy search is made, then ~/.nimbus is
consulted, then ~/.globus. See the README for details.
</p>
<p>
This means one less user step in many of the common ways people use
the cloud client. The new <b>optional</b>'nimbus.cert' and
'nimbus.key' properties also makes toggling between clouds easier.
