 - **Add: `ModelPool` for LLM fallback and load-balancing**: Introduced `ModelPool` as a drop-in replacement for `Model` - use `by pool()` exactly like `by llm()`. Internally wraps a LiteLLM `Router` running in-process (no subprocess, no proxy server) that handles fallback, retries, and load-distribution across a list of `Model` instances. Exported from `byllm.lib`. Six routing strategies are supported: `"fallback"` (ordered priority, next model on failure), `"simple-shuffle"` (random pick per call - ideal for free-tier key rotation across multiple API keys), `"cost-based-routing"` (cheapest deployment via LiteLLM's built-in cost database), `"latency-based-routing"` (fastest by EWMA-tracked response time), `"usage-based-routing"` (lowest current TPM/RPM usage), and `"least-busy"` (fewest in-flight requests). Backward compatible - no changes needed to existing `by llm()` call sites.
 - **Add: Global `ModelPool` defaults via `jac.toml`**: A new `[plugins.byllm.fallback]` section in `jac.toml` provides global defaults for `ModelPool` construction - `strategy` (default `"fallback"`), `num_retries` (default `1`), and `timeout` (default `60.0` seconds).

+## byllm 0.6.2
 
 - **Type Safety: `BaseLLM` implements `LLMModel` protocol**: `BaseLLM` now extends the `LLMModel` protocol defined in jaclang core, and the byllm plugin's `default_llm` hook returns `LLMModel` instead of `object`. This enables type-safe LLM model references across the full chain from the type checker through the runtime.

 - **Content QA fixes**: Updated `root` to `root()` in pitfalls and knowledge map to match current deprecation (W0062). Fixed invalid graph filter syntax `` [-->](`?B) `` → `[-->][?:B]` in pitfalls. Updated `root spawn` → `root() spawn` in client-side examples.
 - **New doc mappings**: Added `jac://docs/tutorial-fullstack-npm`, `jac://docs/tutorial-fullstack-advanced`, and `jac://docs/diagnostics` to DOC_MAPPINGS and knowledge map. Bundled docs updated.
 
-## jac-mcp 0.1.9 (Latest Release)

 - 1 small refactor/change.
 - **Knowledge map tools**: `understand_jac_and_jaseci` and `get_resource` tools for on-demand doc fetching with size-tagged URIs, expanded fullstack coverage, enum-validated example categories, and leaner tool/server descriptions.

 - **Pre-built Admin Dashboard**: The admin dashboard UI is now pre-built during the release process and shipped as static assets in the package. Previously, navigating to `/admin/` on first load triggered a full Vite build from source, causing significant lag. The server now copies bundled assets instantly, falling back to source build only in dev mode.
 - **Dev Mode: Named endpoints in Swagger docs**: Dev mode (`jac start --dev`) now registers individual named endpoints (e.g. `/walker/read_todos`) instead of generic catch-all routes (`/walker/{walker_name}`), so Swagger UI shows all walker/function names. HMR still works - routes are refreshed automatically on file changes.

 - **Native: Lambda Expressions and Capturing Closures**: Added lambda expression support in the `na` (native LLVM) codespace. Simple lambdas compile to anonymous LLVM IR functions returned as function pointers. Capturing closures -- lambdas that reference variables from the enclosing scope -- pass captured values as hidden extra parameters, with automatic injection at call sites. No heap allocation required for captures. Leverages the existing indirect function pointer call infrastructure.

 - **Native: Lambda Expressions**: Added lambda expression support in the `na` (native LLVM) codespace. Lambdas compile to anonymous LLVM IR functions returned as function pointers. Leverages the existing indirect function pointer call infrastructure for invocation.
 - **Type Checker: Expression-Based CFG Narrowing for Dotted Paths**: The type checker now narrows dotted attribute expressions (e.g., `obj.field`) through the CFG backward walk, not just simple variable names. Patterns like `if obj.speed is None { obj.speed = 0; } return obj.speed;` now correctly resolve `obj.speed` to `int` instead of `int | None`. Introduced `NarrowingTarget` abstraction to generalize the CFG narrowing pipeline for both symbols and expression keys, extended `affected_symbols` to track dotted paths, and removed scope-based narrowing for dotted paths in favor of the more precise CFG analysis that accounts for assignments inside branches.
