PR Summary

Medium Risk
Changes affect URL/path construction and query serialization, which can alter request shapes and potentially break edge-case integrations. CI/test tool refactors and dependency bumps add some churn but are well-scoped.

Overview
Releases 1.21.0 and updates packaging metadata (pyproject.toml, _version.py, release manifest, changelog).

Adds safer request path interpolation via new path_template() (percent-encodes path params and rejects dot-segments) and switches generated generations endpoints to use it instead of f-strings.

Extends query/form serialization to support indices array format, refines Pydantic compatibility to only pass by_alias when explicitly set, bumps minimum typing-extensions, and updates test tooling/scripts/docs from Prism to Steady (including new .stdy.log ignore and CI tweaks to skip lint/build on metadata-only pushes).

Bugbot Autofix prepared a fix for the issue found in the latest run.

• ✅ Fixed: Local variable shadows its own function name
  • Renamed the local path_template variable to path_template_part to remove function-name shadowing without changing behavior.

Local variable shadows its own function name

Low Severity

The local variable path_template on this line shadows the enclosing function also named path_template. While this doesn't cause a runtime bug today (no recursive call is made), it creates confusing code where the same identifier refers to different things depending on scope. It also prevents any future recursive usage and can confuse IDE navigation and static analysis tools. A name like path_part would avoid the ambiguity.
