v0.4.25 — Synced to Vercel Chat 4.25.0

Synced to Vercel Chat 4.25.0. New versioning: 0.{upstream_major}.{upstream_minor} embeds the upstream version directly.

Upgrading

pip install chat-sdk==0.4.25

Version scheme changed from 0.0.1aX to 0.{upstream_major}.{upstream_minor}[.patch]. Check chat_sdk.UPSTREAM_PARITY programmatically.

New features (from upstream 4.25.0)

• Plan blocks: Post structured task lists with live updates.

  plan = Plan(title="Deploy steps")
  posted = await thread.post(plan)
  await plan.add_task("Build image")
  await plan.update_task(0, status="completed")
  await plan.complete()

• Streaming table option: StreamingMarkdownRenderer(wrap_tables_for_append=False) for platforms with native table support. Slack uses this by default.
• Teams Select/RadioSelect: Card elements render as Adaptive Card Input.ChoiceSet with auto-submit.
• GitHub issue threads: issue_comment webhooks on plain issues create threads with github:owner/repo:issue:42.
• Slack OAuth redirect fix: handle_oauth_callback correctly forwards redirect_uri.

Python-only improvements (not in upstream)

• PostableObjects cached in message history with real message ID (upstream skips this)
• Teams msteams transport key stripped from action values (upstream leaks it)
• End-to-end integration tests for Teams card inputs
• GitHub fetch_thread round-trip test with channel APIs

Internals

• 3,421 tests, 0 warnings, 0 lint errors
