+# 0.4.0
+
+**Tag:** `v0.4.0` · **Date:** 2026-07-31
+
+All changes since [`v0.3.1`](v0.3.1.md).
+
+A **dependency-update release** of the four lockstep packages (`Andes.Extensions.AI`, `Andes.Extensions.AI.Mcp`, `Andes.Extensions.AI.Agent`, `Andes.Extensions.AI.UI`). There are **no code, API, or behavioral changes** relative to 0.3.1 — no `.cs` file changed; only the central pins in `Directory.Packages.props` moved, and those pins become the dependency floors the published packages declare on nuget.org.
+
+## Changed
+
+- **`Andes.Extensions.AI.Mcp` now requires `ModelContextProtocol.Core` >= 2.0.0** (was `>= 1.4.1`) — a major release of the MCP C# SDK, published 2026-07-28 and aligned with the MCP **2026-07-28 specification** (see the [SDK release notes](https://github.com/modelcontextprotocol/csharp-sdk/releases/tag/v2.0.0)). MCP 2.0 carries its own breaking changes and deprecations for consumers (stateless-by-default HTTP; Roots, Sampling, and Logging obsoleted), which is why this is a minor bump (0.3.1 → 0.4.0) rather than a patch despite no code changes in this repository.
+  - The `Andes.Extensions.AI.Mcp` source itself compiled against MCP 2.0 with **zero warnings** (warnings are errors) and required no migration — it uses none of the APIs MCP 2.0 deprecates (Roots/Sampling/Logging).
+- **Core now floors `Microsoft.Extensions.AI` >= 10.8.3** and **`Andes.Extensions.AI.UI` floors `Microsoft.Extensions.AI.Abstractions` >= 10.8.3** (both were `>= 10.8.1`).
+- **`Andes.Extensions.AI.Agent` now floors `Microsoft.Agents.AI` >= 1.16.0** (was `>= 1.15.0`).
+- The remaining pin updates — `ModelContextProtocol` 1.4.1 → 2.0.0 and `Microsoft.Extensions.AI.OpenAI` 10.8.1 → 10.8.3 — are consumed only by the tests, the test MCP server, and the demo sample, none of which ship to NuGet.
+- **All four packages version in lockstep at 0.4.0**; the satellites depend on core `>= 0.4.0`.
+
+## Verification
+
+`dotnet build` clean with zero warnings against the new pins (warnings are errors). `dotnet test` — 136/136 tests green, including the Azure OpenAI integration suites and the MCP integration tests that spawn the stdio `Andes.Extensions.AI.TestMcpServer` against the real MCP 2.0 SDK.
