Release: Python SDK v3.45.0

Slack Python SDK v3.45.0 adds Slack Code API methods for managing code channels, canvases, commands and views.

You can use setView to create or update a tab with HTML, a diff, Block Kit blocks, a canvas or a pull request. It requires a granular bot token with the code_channels:manage scope, and special rate limits apply. A channel can hold up to 5 views, with at most one diff.

The release also adds ContainerBlock support and lets TableBlock cells use raw_number values.
