Includes automatic process cleanup on exit.

Bug Fixes

• Tasks can no longer be nested inside a trace (#636) — Tasks called from within a trace now correctly run as plain Python instead of causing errors.

Improvements

• Faster imports (#638) — Improved import optimization to reduce startup time.

Full Changelog: v2.0.0b55...v2.0.0b56

v2.0.0b55

Highlights

Introducing the Local TUI

A new Terminal UI for local Flyte runs lets you visualize your workflow executions, inspect inputs/outputs, view caching status, and access reports — all from your terminal. (#621)

Anthropic Claude Plugin

New first-class plugin for integrating Anthropic's Claude API with Flyte. Includes a function_tool decorator to convert Flyte tasks into Claude tool definitions, automatic Python type-to-JSON-schema conversion, and an Agent class for running agentic loops. (#612)

Typed Interface Migration

Task interfaces now use ordered slices instead of variable maps, preserving input/output ordering. (#558)

---

New Features

• First-class TypedDict support — TypedDict values are now serialized with full observability in the Flyte UI instead of being pickled, improving compatibility with AI frameworks like LangGraph and PydanticAI. (#613)
• First-class tuple and NamedTuple support — Tuples and named tuples are converted to Pydantic BaseModels under the hood, supporting complex nested subtypes including File, Dir, dataclasses, and more. (#597)
• Enum support in Pydantic models — Enum fields in Pydantic BaseModel types are now handled correctly instead of crashing with a KeyError. (#622)
• Dynamic DAG generation from YAMLs — Workflows can now be dynamically generated from YAML configuration files. (#619)
• Snowflake connector improvements — Added DataFrame conversion support, automatic input batching with batch=True, secret_group parameter for simplified secret management, and updated docstrings. (#584)

Bug Fixes

• Large IO buffer leak — Large IO write operations now properly close the buffer. (#625)
• DataFrame local sync in nested types — Fixed DataFrame synchronization when used inside nested type structures. (#620)
• BigQuery credentials parsing — Fixed credentials parsing and a secret key typo. (#606)
• .egg-info directories ignored during file copy — These directories are no longer inadvertently included when copying files. (#617)

Cleanup & Maintenance

• Removed BigQuery handlers from the dataframe module. (#624)
• Removed get_cwd_editable_install function. (#615)

Full Changelog: v2.0.0b54...v2.0.0b55

v2.0.0b54

⏺ ## Flyte SDK v2.0.0b54 Changelog

Highlights

Connectors are now separate packages — BigQuery, Databricks, and Snowflake connectors have been split into
independent PyPI packages (flyteplugins-bigquery, flyteplugins-databricks, flyteplugins-snowflake), each with their
own versioning and release cycle. The old monolithic flyteplugins-connectors package is removed.
(#595)

Migrated off legacy flyteidl — The SDK now uses flyteidl2 for data proxy and removes the legacy flyteidl
dependency entirely. This is a significant internal modernization.
(#523, #526)

---

New Features

• W&B distributed training support — The Weights & Biases plugin now supports tracking single-node and multi-node
  distributed training via the PyTorch plugin, with dashboard links for per-worker logs.
  (#600)
• Skip image builds for connector tasks — Snowflake and BigQuery tasks can now set image=None to skip container
  image building entirely, since these tasks run on the connector side.
  (#559)
• Optional uv.lock in UVProject — You can now build images from pyproject.toml-only projects without requiring a
  uv.lock file. (#596)
• CLI option dependencies — Added RequiresOption so that dependent CLI flags (e.g., --docker-config-path
  requiring --from-docker-config) now produce clear error messages instead of silently misbehaving.
  (#586)
• Fanout cancellation example — New example workflow demonstrating how to handle UI-canceled actions in fanout
  groups. (#589)

Bug Fixes

• Duplicate secrets in image builds — Fixed an issue where the same secret used across multiple image layers (e.g.,
  with_apt_packages and with_pip_packages) was added multiple times to build commands.
  (#604)
• .dockerignore pattern matching — Fixed broken .dockerignore support — patterns like **, !negation, and
  *.pyc now work correctly, preventing bloated Docker images with cache/build artifacts.
  (#550)
• DataFrame local-to-remote — Fixed an issue where a flyte.io.DataFrame created locally could not be passed as
  input to a remote run. Also added preserve_original_types option to with_runcontext for better type fidelity in
  run.outputs(). (#594)

Improvements

• Machine-readable JSON output — Rich formatting (spinners, colors, panels) is now disabled when using --log-format json or table-simple, ensuring clean machine-parseable output.
  (#587)
• Better error messages for Layer classes — List validation in image Layer classes now provides helpful error
  messages instead of cryptic stack traces. (#593)
• S3 storage config fix — Fixed endpoint_url vs endpoint mismatch between s3fs and obstore backends.
  (#592)

Maintenance

• Bumped protobuf from 6.33.0/6.33.2 to 6.33.5 (#601,
  #603)
