Informal CBU release - to ease reproducibility and data sharing, we make releases whenever the deployed version on the CBU imaging system changes.
The major change in this release is to implement a toolbox functionality for supporting libraries like EEGLab and SPM. The long-term vision here is to only have libraries that a particular module needs on the path at any time, rather than requiring the kitchen sink on the path throughout. This change will break your defaults file, since some paths have moved from <aap><directory_conventions<spmdir>, <eeglabdir>, and <fieldtripdir> to <toolbox>. The solution if you're using the new user-specific defaults approach is to remove this file (by default something like mv ~/.aa/aap_parameters_user.xml ~/.aa/aap_parameters_user.xml.bak should work), and re-run to seed a new defaults file from the updated CBSU defaults. If you have a project-specific defaults file this will need updating manually.
