Release Notes: 7.5

We are happy to announce DipDup 7.5! This release focuses on improving compatibility with various EVM blockchains, performance improvements, and bug fixes.

DipDup has been tested with many EVM networks, both with Subsquid and node datasources. Check out the EVM networks page to see the list of supported networks and their configuration examples.

New config option http.polling_interval allows setting the interval between polling requests. This setting applies only to some datasources in specific cases. For example, when using the evm.subsquid datasource without nodes attached or the evm.node datasource without WebSocket realtime subscriptions.

A bunch of performance improvements have been made in this release. DipDup now indexes EVM chains faster, collects more metrics for memory caches, and is less hungry for resources overall.

The Hasura adapter now supports the bulk request type to apply table customizations faster and organize custom metadata files more conveniently.

Finally, DipDup 6.5, the stable release branch, has reached end-of-life. 6.5.16 is the last release in this branch. Please, follow the 7.0 Migration Guide to upgrade to the latest version.
