What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

---

- **added** — Support selecting a thinking effort level from ACP clients with the thinking picker listing the current model's declared levels instead of only an on/off toggle
- **added** — Allow custom agent files to restrict which sub-agent types they may delegate to (v2 engine only)
- **added** — Support custom agents defined as Markdown files with frontmatter, usable as the main agent or a sub-agent (v2 engine only)
- **added** — Add global tool gating to constrain which tools agents may use, with a per-session override (v2 engine only)
- **added** — Add a GET /api/v1/fs:content server endpoint that serves any file on the host by absolute path as raw content with Content-Type, ETag, and Range support
- **added** — Videos attached to a prompt now reach the model together with the prompt with no extra tool round trip and stay playable in the chat after a reload
- **added** — Support overriding the default main-agent system prompt with a user-level file for every session (v2 engine only)
- **added** — Add agent.created and agent.disposed events to the server session event stream and expose each agent's disposal time in the transcript API
- **added** — Add environment variable overrides for agent loop and background task limits with KIMI_LOOP_MAX_STEPS_PER_TURN, KIMI_LOOP_MAX_RETRIES_PER_STEP, or KIMI_CODE_BACKGROUND_MAX_RUNNING_TASKS
- **changed** — Import many more providers from the models.dev catalog including vendor SDKs like xai and openrouter with per-model gateway protocol and endpoint overrides honored
- **fixed** — Fix catalog-imported Claude models being wrongly locked into always-on thinking and stop offering a misleading thinking Off option for models that cannot truly disable reasoning
- **fixed** — Fix config environment overrides being persisted into config.toml by config API writes while the env var is set
- **fixed** — Remove references to the non-existent kimi resume command from the scheduled-task tool descriptions
- **fixed** — Fix cancelled model requests being wrapped as retryable provider errors so interrupting a request no longer triggers silent retries

###### Minor Changes

- [#1992](https://github.com/MoonshotAI/kimi-code/pull/1992) [`a8f1ca3`](https://github.com/MoonshotAI/kimi-code/commit/a8f1ca3f1016a3e84986f297367e833bc731ac39) Thanks [@RealKai42](https://github.com/RealKai42)! - Support selecting a thinking effort level from ACP clients: the thinking picker now lists the current model's declared levels (for example off / low / medium / high) instead of only an on/off toggle. Use the thinking selector in your ACP client (e.g. Zed) to pick a level; the legacy on/off values keep working.
