Dec 1, 2025

2025-12 monthly summary for speakeasy; major delivery includes a new Persistent Edits workflow that lets users apply and preserve custom code changes on top of generation targets, with local conflict resolution prompts and a patch maintenance flow to avoid overwriting user edits. In parallel, key reliability and UX improvements were shipped via three bug fixes that together enhance business value and platform stability: improved cross-platform OpenAPI generation (Windows compatibility and orphan-file handling) with updated dependencies and tests; checksum stability for custom code workflows with re-enabled prompting to guide users during speakeasy run; and UX simplification by disabling the custom code prompting to reduce terminal compatibility issues and false positives. These changes collectively reduce risk of unintended edits, improve developer productivity, and broaden platform reliability across environments.
