 ## [Unreleased]
 
+### New Features
+
+- Per-model overrides in `models.json` via `modelOverrides`, allowing customization of built-in provider models without replacing provider model lists. See [docs/models.md#per-model-overrides](docs/models.md#per-model-overrides).
+- `models.json` provider `models` now merge with built-in models by `id`, so custom models can be added or replace matching built-ins without full provider replacement. See [docs/models.md#overriding-built-in-providers](docs/models.md#overriding-built-in-providers).
+- Bedrock proxy support for unauthenticated endpoints via `AWS_BEDROCK_SKIP_AUTH` and `AWS_BEDROCK_FORCE_HTTP1`. See [docs/providers.md](docs/providers.md).
+
 ### Breaking Changes
 
 - Changed `models.json` provider `models` behavior from full replacement to merge-by-id with built-in models. Built-in models are now kept by default, and custom models upsert by `id`.
