Release v0.2.0

[lchoquel]

Release v0.2.0

Bumps version from 0.1.1 to 0.2.0.

Changelog

Added

• Added a request_timeout_seconds constructor parameter to PipelexAPIClient, setting a per-instance blocking-execute ceiling for the inherited protocol routes (execute, start, validate, models, version).

Changed

• BREAKING: Renamed PipelexAPIClient constructor parameters and attributes to match the mthds base client and the @pipelex/sdk JavaScript counterpart: api_token → api_key and api_base_url → base_url. (Migration: update all instantiations and property reads to the new names.)
• BREAKING: Renamed API URL environment variables for workspace-wide consistency: PIPELEX_API_URL → PIPELEX_BASE_URL and the mthds fallback MTHDS_API_URL → MTHDS_BASE_URL. No read aliases are kept for the old names.
• Bumped the mthds dependency from >=0.6.1 to >=0.7.0, and updated config loading to import load_config from mthds.config (previously load_credentials from mthds.config.credentials).
• Updated documentation (README.md, CLAUDE.md, docs/architecture.md) and unit tests to reflect the new client signature, environment variables, and mthds configuration.

Greptile Summary

This PR releases 0.2.0 with renamed client configuration and updated dependency support. The main changes are:

• PipelexAPIClient now uses api_key and base_url naming.
• API URL environment variables move to PIPELEX_BASE_URL and MTHDS_BASE_URL.
• mthds is bumped to >=0.7.0 with load_config usage.
• Docs, changelog, lockfile, and unit tests are updated for the release.

Confidence Score: 4/5

Safe to merge after fixing the missing constructor parameter.

The rename and dependency updates are consistent, but the documented timeout API currently raises TypeError.

pipelex_sdk/client.py

T-Rex Logs

What T-Rex did

• A focused Python repro reproduced the missing timeout parameter issue by attempting to instantiate PipelexAPIClient with request_timeout_seconds=5, which raised a TypeError.
• The constructor rename script was used to compare before and after behavior, confirming old kwargs were accepted and new kwargs rejected before the rename, and that after the rename old kwargs are rejected, new kwargs accepted, attributes renamed, and header behavior updated.
• URL resolution behavior was validated across before/base and after/head scenarios, showing old aliases resolve to service URLs while new base aliases and defaults are honored as expected.
• API version and import path changes were documented and the PIPELEX_BASE_URL usage was noted across README, CLAUDE.md, docs, and migration notes.

Important Files Changed

Filename	Overview
pipelex_sdk/client.py	Renames constructor/config fields and adds timeout storage, but omits the advertised request_timeout_seconds constructor parameter.
tests/unit/test_client_construction.py	Updates construction tests for renamed args/env/config but lacks coverage for the advertised timeout constructor parameter.
pyproject.toml	Bumps package version to 0.2.0 and raises the mthds dependency floor to >=0.7.0.
uv.lock	Updates locked mthds and editable package metadata to match the release bump.
CHANGELOG.md	Documents the v0.2.0 breaking renames and timeout addition; timeout entry currently overstates the implemented constructor API.
README.md	Updates configuration documentation to the new PIPELEX_BASE_URL/MTHDS_BASE_URL names.
docs/architecture.md	Updates architecture docs to describe the new base URL environment variable precedence.
pipelex_sdk/errors.py	Updates lifecycle unavailable error wording to reference PIPELEX_BASE_URL.

### Issue 1 of 1
pipelex_sdk/client.py:158
**Missing timeout parameter**
The release notes and inline docs say callers can pass `request_timeout_seconds`, but the constructor still only accepts `api_key` and `base_url`. `PipelexAPIClient(request_timeout_seconds=...)` raises `TypeError`, so users cannot configure the inherited protocol timeout despite the new documented API.
