Key Highlights

New Qdrant external integration
New MySQL write connector supporting stream of changes and realtime snapshot
DeltaLake connector now accepts start_from_timestamp_ms parameter
Async UDFs now have default ExponentialRetryStrategy
PostgreSQL write now supports stream of changes and realtime-updated snapshot

New Features

Qdrant external integration
pw.io.mysql.write connector
pw.io.deltalake.read start_from_timestamp_ms parameter
Default retry strategy for async UDFs
pw.io.postgres.write output_table_type parameter
Deprecation of pw.io.postgres.write_snapshot

Full Release Notes

### Added
- New external integration with [Qdrant](https://qdrant.tech/).
- `pw.io.mysql.write` method for writing to MySQL. It supports two output table types: stream of changes and a realtime-updated data snapshot.

### Changed
- `pw.io.deltalake.read` now accepts the `start_from_timestamp_ms` parameter for non-append-only tables. In this case, the connector will replay the history of changes in the table version by version starting from the state of the table at the given timestamp. The differences between versions will be applied atomically.
- Asynchronous UDFs for connecting to API based llm and embedding models now have by default retry strategy set to `pw.udfs.ExponentialRetryStrategy()`
- `pw.io.postgres.write` method now supports two output table types: stream of changes and realtime-updated data snapshot. The output table type can be chosen with the `output_table_type` parameter.
- `pw.io.postgres.write_snapshot` method has been deprecated.
