We're also open to volunteers if you want to submit a PR for any open issues but please discuss it with us beforehand. PRs that aren't linked to an existing issue or discussed with us ahead of time will generally be declined. If you have more general feedback or want to discuss using this client with other users, feel free to reach out on our Slack channel.

Release planning

This client will attempt to follow the release cadence of our API. When endpoints are deprecated and newer versions are added, the client will maintain two methods in a backwards compatible way (e.g. list_trades and list_trades_v4(...)). When deprecated endpoints are removed from the API, we'll rename the versioned method (e.g. list_trades_v4(...) -> list_trades(...)), remove the old method, and release a new major version of the client.

The goal is to give users ample time to upgrade to newer versions of our API before we bump the major version of the client, and in general, we'll try to bundle breaking changes like this to avoid frequent major version bumps.

Exceptions to this are:

• Methods under client.vx. These are expiremental.
• Methods that start with _*. We use these internally.
• Type annotations. We may modify these based on our JSON responses.
• We may add model fields.
