# create_version improvements and patch fixes

**Version:** v2.17.1

**Published:** April 17, 2026

## Improvements

- `create_version`** **tool: Simplified the response and added follow-up guidance for editing version documents with `patch_document_from_json` or `patch_document_from_markdown`.

## Fixes

- `patch_document_from_json`** **tool: Numeric array indices are now rejected, and patch execution has been simplified for more predictable behavior.
- Authentication: `/token` responses now include `Cache-Control: no-store` to prevent caching of OAuth tokens.
