# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [1.0.1] - 2026-04-16

### Changed
- **Renamed package** from `mcp_ex` to `mcp_elixir_sdk` (the `mcp_ex` hex name was previously taken by another client-only library). The new name follows the official MCP SDK naming convention (`mcp-go-sdk`, `mcp-python-sdk`, `mcp-ruby-sdk`, `mcp-typescript-sdk`).
- Top-level OTP application module renamed from `McpEx.Application` to `MCPElixirSDK.Application` (internal, not part of the public API).
- Default `client_info`/`server_info` name updated to `mcp_elixir_sdk`.

### Note
Public module names under the `MCP.*` namespace (e.g. `MCP.Client`, `MCP.Server`, `MCP.Server.Handler`, `MCP.Transport.*`) are unchanged, so existing code using these modules continues to work — only the dependency declaration needs updating.
