Key Highlights

Kafka connectors now support OAUTHBEARER authentication.
MongoDB write connector supports 'stream_of_changes' and 'snapshot' modes.
Automatic worker scaling based on pipeline load configuration.
PostgreSQL write connector now properly supports TLS configuration.

New Features

OAUTHBEARER authentication for Kafka read/write.
New `output_table_type` parameter for MongoDB connector.
Automatic worker scaling feature via `pw.persistence.Config`.
TLS configuration support for PostgreSQL connector.
Retry logic for initial connection requests in `pw.xpacks.connectors.read`.

Full Release Notes

### Added
- `pw.io.kafka.read` and `pw.io.kafka.write` connectors now support OAUTHBEARER authentication.
- `pw.io.mongodb.write` connector now supports an `output_table_type` parameter with two modes: `stream_of_changes` (default) and `snapshot`. In `snapshot` mode, the connector maintains the current state of the Pathway table in MongoDB using the `_id` field as the primary key, while `stream_of_changes` preserves the existing behavior by writing all events with `time` and `diff` flags to reflect transactional minibatches and the nature of each change.
- Workers can now automatically scale up or down based on pipeline load, using a configurable monitoring window. This feature requires persistence to be enabled and can be configured via `worker_scaling_enabled` and `workload_tracking_window_ms` in `pw.persistence.Config`. Please refer to the tutorial for more details.
- `pw.io.postgres.write` now properly supports TLS configuration via `sslmode` and `sslrootcert` connection string parameters.

### Changed
- `pw.xpacks.connectors.read` now retries initial connection requests.
