SDK Updates: v4.0.0

[postman]

SDK updates

Added

• Generated .github/workflows/release.yml workflow for automated releases and PyPI publishing (controlled by publishing.enabled and publishing.releaseBranch in the generate request)

Changed

• Server URL normalization now handles prose-bearing values from OpenAPI specs and Postman collections, extracting the first valid https?:// URL token and falling back gracefully when no URL can be found

Fixed

• PyPI publish step in generated release workflow now includes skip-existing: true to allow re-running workflows without failure
• typing.Any-typed fields no longer raise TypeError at runtime during validation
• Generated SDKs now construct cleanly when server URLs contain prose (like "POST https://api.example.com"), malformed values fall back to a placeholder, and relative paths and non-HTTP schemes like grpc:// are preserved
• IPv6 host URLs are automatically bracketed per RFC 3986 (e.g., https://[2001:db8::1]/v1) to prevent validation errors; colon-heavy authorities that are not valid IPv6 literals now fall back to a placeholder instead of producing an Invalid IPv6 URL error
• Requests to operations without a request body no longer send an empty JSON payload with a Content-Type: application/json header, so strict servers no longer reject them with HTTP 415
• Pattern validation using regex fields now works reliably; patterns with Python-incompatible constructs (look-behind, atomic groups, possessive quantifiers, conditional groups, Unicode escapes, named backreferences) are safely translated or skipped instead of crashing at schema load
• Pattern validation in Pydantic fields now respects backslash escapes correctly in raw strings
