• The default of the configuration option "num_engine_workers" has changed from 1 to a number based on the the number of CPUs. This is now the same as the way other projects set the number of workers.
• The default for the configuration option "max_nested_stack_depth" has been increased to 5.
• There is a new configuration option "convergence" it is by default off. This feature is not yet complete and this option should remain off.
• In preparation of an upcoming major feature (convergence) there have been some significant DB schema changes. It is suggested that the heat-engine is shutdown during schema upgrades.
