### Changed
*
*
* `publish` to accept bid as a decimal string
* all JSONRPC API commands are now registered asynchronously and are available to be called as soon as they are ready
### Added
* Component Manager for managing the dependencies, startup and stopping of components
* `requires` decorator to register the components required by a `jsonrpc_` command, to facilitate commands registering asynchronously
* added unittests for Component Manager
*
*
### Removed
* `STARTUP_STAGES` from `status` API and CLI call, it instead returns a dictionary of components along with their running status(this is a **potentially breaking change** if `STARTUP_STAGES` is relied upon)
* all component startup code from `Daemon.py`
* wallet, upnp and dht startup code from `session.py`, the code now resides in `Components.py`
*
*
