- Models/commands: add `/models add <provider> <modelId>` so you can register a model from chat and use it without restarting the gateway; keep `/models` as a simple provider browser while adding clearer add guidance and copy-friendly command examples. (#70211) Thanks @Takhoffman.

- Pi/models: update the bundled pi packages to `0.68.1` and let the OpenCode Go catalog come from pi instead of plugin-maintained model aliases, adding the refreshed `opencode-go/kimi-k2.6`, Qwen, GLM, MiMo, and MiniMax entries.

- CLI/doctor plugins: lazy-load doctor plugin paths and prefer installed plugin `dist/*` runtime entries over source-adjacent JavaScript fallbacks, reducing the measured `doctor --non-interactive` runtime by about 74% while keeping cold doctor startup on built plugin artifacts. (#69840) Thanks @gumadeiras.

- CLI/debugging: add an opt-in temporary debug timing helper for local CLI performance investigations, with readable stderr output, JSONL capture, and docs for removing probes before landing fixes. (#70469) Thanks @shakkernerd.

- WhatsApp/groups+direct: forward per-group and per-direct `systemPrompt` config into inbound context `GroupSystemPrompt` so configured per-chat behavioral instructions are injected on every turn. Supports `"*"` wildcard fallback and account-scoped overrides under `channels.whatsapp.accounts.<id>.{groups,direct}`; account maps fully replace root maps (no deep merge), matching the existing `requireMention` pattern. Closes #7011. (#59553) Thanks @Bluetegu.

- Plugins/startup: prefer native Jiti loading for built bundled plugin dist modules on supported runtimes, cutting measured bundled plugin load time by 82-90% while keeping source TypeScript on the transform path. (#69925) Thanks @aauren.

- Plugin SDK/Pi embedded runs: add a bundled-plugin embedded extension factory seam so native plugins can extend Pi embedded runs with async runtime hooks such as `tool_result` handling instead of falling back to the older synchronous persistence path. (#69946) Thanks @vincentkoc.
