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'.

---

- **changed** — The kimi acp subcommand no longer honors KIMI_CODE_LEGACY_FLAG and always runs on the default agent engine
- **changed** — The subagent model pool (secondary_model) is enabled by default in every launch mode and remains opt-out via KIMI_CODE_EXPERIMENTAL_SECONDARY_MODEL=0 or [experimental] secondary-model = false
- **added** — Added a Plugins panel to Settings for browsing the plugin marketplace and installing, enabling, disabling, and removing plugins
- **changed** — Remove the workspace restriction on the Bash tool's cwd parameter
- **added** — Added a code wrap toggle to the diff panel and streamlined its header
- **fixed** — Fixed new content not appearing after auto-compaction (stuck at "Requesting…" above the divider); output after the compaction point now renders below the divider
- **fixed** — Preserve comments, key order, and formatting in config.toml when configuration values are updated
- **fixed** — Fix models and providers transiently disappearing when config.toml is saved non-atomically by an external editor while the daemon reloads it
- **added** — The connecting splash screen now shows the current loading stage and the reason when the connection fails
- **added** — Block dangerous shell commands such as shutdown, reboot, or rm -rf in Auto mode, and always ask before running them in Manual and YOLO modes; disable the guard with [permission] dangerous_command_guard = false or KIMI_CODE_DANGEROUS_COMMAND_GUARD=false
- **fixed** — Fixed queued or steered messages being unexpectedly retracted by pressing Esc after they start running
- **changed** — Make session forks much faster
- **added** — Show a refresh button in the right-sidebar file preview when the previewed file is edited mid-turn
- **fixed** — Fixed the server-side attachment notice text leaking into your own message bubble after sending a file
- **fixed** — Fixed misaligned content in the composer attachment tooltip
- **fixed** — Fixed messages sent with Ctrl+S while the agent is running disappearing after a page reload
- **fixed** — Fixed sessions occasionally stuck showing "working" after a message is appended mid-turn
- **fixed** — Fix duplicate user messages in transcript clients
