Alchemi v.1.0.6 (Developer release) has been released

I almost missed this announcement since I am still battling with the version 1.0.5 and Now I am in the process of upgrading to the 1.0.6 version. If you wonder what Alchemi is;
Alchemi is a software framework that allows you to painlessly aggregate the computing power of networked machines into a virtual supercomputer (computational grid) and to develop applications to run on enterprise grids.
The release of version 1.0.6. brings with it following major changes since 1.0.5, which are a LUA (Least Privileged User Account) operation for both Manager, Executor in normal and service mode and an option for executing user's GThreads in a secure sandbox (experimental)
Before downloading and running the new version,Please note that this is a developer release intended for enthusiasts and early adopters as documentation is not up to date.
Here are the release notes;
This release contains some small important new features.

- The Manager, Executor are now designed run under least-privileged user accounts by default. In service mode, they run as 'LocalService' - which is a limited privilege user account.
- The Manager, Executor will (in both normal and service mode), will now read / write config files from the users' AppData directory.
In Windows XP, this would be :
C:\Documents and Settings\\Application Data\Alchemi\Manager

C:\Documents and Settings\\Application Data\Alchemi\Executor
- The logs are located in the user's Temp directory which would be (in Windows XP),

C:\Documents and Settings\\Local Settings\Temp\Alchemi\Manager\logs


C:\Documents and Settings\\Local Settings\Temp\Alchemi\Executor\logs

- This changes mean that an Administrator or user with admin privileges can install Alchemi, and start up the services, while any user can run Alchemi and/or clients without needing admin rights.
- Added Sandboxed execution for optionally running user's GThreads under low privileges. (These options are not all exposed through the GUI / API yet)
