### Minor Changes
- [#1243](https://github.com/MoonshotAI/kimi-code/pull/1243) [`ace7901`](https://github.com/MoonshotAI/kimi-code/commit/ace79010669d19ad175bc25443b6efb41ca2e2ac) - Automatically compress oversized images before they reach the model. Whatever the source — pasted into the CLI, uploaded from the web/desktop client, sent over ACP, read via `ReadMediaFile`, or returned by an MCP tool — images are downsampled (longest edge ≤ 2000px) and re-encoded to fit a per-image byte budget, cutting vision-token cost and avoiding provider image-size errors. Screenshots stay lossless PNG and only degrade to JPEG when the byte budget cannot otherwise be met. Compression runs as an input-stage step at each ingestion point (while the content part is built), and guards against decompression bombs by skipping absurdly large pixel/byte payloads before decoding. Best-effort: if it fails for any reason the original image is sent unchanged.
- [#1262](https://github.com/MoonshotAI/kimi-code/pull/1262) [`c070fbe`](https://github.com/MoonshotAI/kimi-code/commit/c070fbeddeb1c147d8859a76046f9465f696c9cb) - Add model alias overrides so manual thinking effort levels and model metadata survive provider catalog refreshes. Set them under `[models."<alias>".overrides]`.
- [#1258](https://github.com/MoonshotAI/kimi-code/pull/1258) [`b905dd4`](https://github.com/MoonshotAI/kimi-code/commit/b905dd49108c567d0fecd38a096808c121672795) - Refresh the web UI with a new design system, including updated colors, typography, spacing, light and dark palettes, restyled tooltips, and subtle enter/exit and expand/collapse animations.
