### Fixes

- Models/Kimi: default bundled Kimi thinking to off and normalize Anthropic-compatible `thinking` payloads so stale session `/think` state no longer silently re-enables reasoning on Kimi runs. (#68907)

- Control UI/cron: keep the runtime-only `last` delivery sentinel from being materialized into persisted cron delivery and failure-alert channel configs when jobs are created or edited. (#68829) Thanks @tianhaocui.

- OpenAI/Responses: strip orphaned reasoning blocks before outbound Responses API calls so compacted or restored histories no longer fail on standalone reasoning items. (#55787) Thanks @suboss87.

- Cron/CLI: parse PowerShell-style `--tools` allow-lists the same way as comma-separated input, so `cron add` and `cron edit` no longer persist `exec read write` as one combined tool entry on Windows. (#68858) Thanks @chen-zhang-cs-code.
