Migration (0.5.x to 0.6.x)
On this page
Key breaking changes from 0.5.x to 0.6.x:
Template routing API removals#
Removed APIs:
ChatTemplateEngine.registerHandler(...)ChatTemplateEngine.unregisterHandler(...)ChatTemplateEngine.clearCustomHandlers(...)ChatTemplateEngine.registerTemplateOverride(...)ChatTemplateEngine.unregisterTemplateOverride(...)ChatTemplateEngine.clearTemplateOverrides(...)
Removed per-call routing fields:
- render param:
customHandlerId - parse param:
handlerId
Error behavior changes#
Template render/parse no longer silently downgrades to content-only fallback when handler/parser execution fails. Failures now surface to callers.
Migration tasks#
- Remove all calls to removed template handler registration APIs.
- Remove legacy handler routing fields from request paths.
- Add explicit error handling where fallback behavior was previously expected.
- Re-test tool-calling and template-specific parsing paths.
