🚨 Breaking changes

MCP schema types refactor (#​386)

The MCP schema implementation has been updated to the latest MCP spec and reorganized into dedicated packages:

• All MCP types moved to io.modelcontextprotocol.kotlin.sdk.types package
• Many schema types have new fields and updated constructor signatures
• Request/response types now use nested params objects

Migration:

// Before:
import io.modelcontextprotocol.kotlin.sdk.InitializeRequest
import io.modelcontextprotocol.kotlin.sdk.Resource

// After:
import io.modelcontextprotocol.kotlin.sdk.types.InitializeRequest
import io.modelcontextprotocol.kotlin.sdk.types.Resource

---

Minimum JVM version raised to 11 (#​394)

The minimum supported JVM version is now 11. Projects running on Java 8 must upgrade their runtime and build toolchain.

---

Transport.send signature change (#​408)

The Transport.send method now accepts TransportSendOptions? parameter to support resumption tokens, progress callbacks, and request–response association.

[!NOTE]
Who is affected?
Only custom Transport implementations. Built-in transports require no changes.

Migration:
Update all Transport.send implementations to include the new TransportSendOptions? parameter.
