- Application configuration is now stored in the resources folder as "application.yml".
- ConfigReader to parse YAML and JSON config files
- A convenient MultiLevelDict class for reading key-values using the dot-bracket notation (e.g. "my.config.key[0]")
- Support nested arrays in MultiLevelDict

- Store-n-forward pub/sub API will be automatically enabled if the underlying cloud connector supports it. e.g. kafka
- ObjectStreamIO, a convenient wrapper class, to provide event stream I/O API.
- Object stream feature is now a standard feature instead of optional.
- Deferred delivery example in demo.py
- Add inactivity expiry timer to ObjectStreamIO so that house-keeper can clean up resources that are idle
N/A
Bug fix - update EventEnvelope with missing field "extra" which is used as additional routing information for language packs. This allows correct RPC routing between python applications via the language connector.
