v0.29.0

Breaking Changes

Output connectors: String header values to Kafka/NATS no longer wrapped in quotes; None serializes differently (no value in Kafka, "None" string in NATS)

Pathway Web Dashboard for real-time pipeline monitoring with interactive graphs and latency/memory metrics
pw.io.kafka.read now exposes message headers in metadata as base64-encoded pairs in headers array
pw.xpacks.llm.llms.BedrockChat - AWS Bedrock integration for Claude, Llama, Titan, Mistral via Converse API
pw.xpacks.llm.embedders.BedrockEmbedder - AWS Bedrock embeddings (Titan, Cohere)

Lazy imports for Python dependencies — only loaded when capabilities are actually used

Pathway Web Dashboard providing user-friendly interface for monitoring Pathway pipelines in real time with interactive graph plotting and latency/memory metrics.
pw.io.kafka.read now includes message headers in the parsed metadata. The headers are available at the top level of the metadata in the headers array. Each element of the array is a pair consisting of a string header name and a base64-encoded header value. If the header is null, the corresponding value is also null.
pw.xpacks.llm.llms.BedrockChat - Native AWS Bedrock chat integration using the Converse API. Supports Claude, Llama, Titan, Mistral, and other Bedrock models.
pw.xpacks.llm.embedders.BedrockEmbedder - Native AWS Bedrock embedding integration supporting Amazon Titan and Cohere embedding models.

Most Python dependencies are now imported only if the related capabilities are used by a program.
BREAKING: Output connectors no longer wrap string header values in double quotes when sending them to Kafka or NATS. The string values are forwarded as-is. The None value is handled differently: in Kafka, it is serialized as a header without a value, while in NATS it becomes the string "None".
