v0.10.0

Dynamic data sources

Also referred to as dynamic contract subscriptions, as this is currently the main use case.

This feature supports creating new data sources from templates while indexing the subgraph. The motivation behind this is to provide a natural way of indexing registry/factory contracts that reference many other (sub)contracts.

See Define a Subgraph: Dynamic Data Sources in the docs for more details.
