Upgrade Note

Rust Core

There are no public API and raw API changes.

Java binding

Breaking change for constructing operators

PR-3166 changes the API for constructing operators:

Previous:

new BlockingOperator(scheme, config);
new Operator(scheme, config);

Current:

BlockingOperator.of(scheme, config);
Operator.of(scheme, config);

Now, there is no public constructor for operators, but only factory methods. In this way, the APIs are free to do arbitrary verifications and preparations before constructing operators.

Node.js binding

There are no API changes.

Python binding

There are no API changes.
