New features

Enhanced shell commands

• Support for finding the root cause of a missing dependency;
• Less verbose dm notavail, i.e. only showing those dependencies that are actually missing, leave out the available ones;
• Optimisation help; reporting those dependency filters whose performance can be increased by adding a filter index;
• Add the possibility to choose whether to use the filter index or the service registry when listing services

Additional developer support

• Add annotations which can be used in code analysis tooling. (e.g. callback methods are typically reported as dead code)

Add support for remote services
