- Remove the ability to use an argument vector or argument map to specify arguments for request. All request arguments must now be maps.
- Default/optional arguments are no longer handled by iboga. All arguments required by Interactive Broker's API are now required by Iboga.
- Custom transformers for values to and from IB are now registered via
iboga.core/def-to-ib
andiboga.core/def-from-ib
which take a fully qualified keyword, and a function of the value to be transformed.
