PR Description

When reviewing processWithdrawalRequests, I noticed two differences from the spec.

• if is_full_exit_request: ... return
  • In Teku, this return statement was in the wrong spot. It would only return if we initiated the validator exit.
  • I believe this could have led to a more severe issue; maybe a consensus issue.

• if len(state.pending_partial_withdrawals) == PENDING_PARTIAL_WITHDRAWALS_LIMIT ...
  • In Teku, this was >=. Effectively the same thing & only changing to be consistent with the spec.

Documentation

• I thought about documentation and added the doc-change-required label to this PR if updates are required.

Changelog

• I thought about adding a changelog entry, and added one if I deemed necessary.
