## [Unreleased]

- Implement list changed notifications for prompts, resources, and tools (Streamable HTTP transport only).
- Add `ssl_params` configuration option for Redis connections to support hosted Redis providers with self-signed certificates.
- (Breaking) Refactor streamable HTTP transport to singleton pattern for production use.
- Use `Server.setup { |config| ... }` to initialize once at application boot.
- Use `Server.serve(env:, session_context:)` to handle each HTTP request.
- Use `Server.shutdown` for graceful cleanup on application exit.
- This ensures only 2 background threads exist regardless of concurrent connections.
- (Breaking) Refactor server to use factory methods and singleton pattern.
- Use `Server.with_stdio_transport` or `Server.with_streamable_http_transport` to configure.
- Use `Server.start` to activate the transport.
- Use `Server.serve(env:, session_context:)` to handle HTTP requests.
- Use `Server.shutdown` for cleanup on exit.
- (Breaking) Sessions are now required by default for streamable HTTP transport. Set `require_sessions = false` to opt out.
- (Breaking) Simplify Redis and registry configuration APIs.
- Add Puma plugin (`puma/plugin/mcp`) to manage server lifecycle automatically.
- Add RSpec matchers for testing MCP handlers (e.g., `be_valid_mcp_tool_response`, `have_text_content`).
- Add tool annotations and security schemes.
- Add spec-compliant session management.
- Add list changed notifications for prompts, resources, and tools (streamable HTTP transport only).
- Add `session_context` parameter to `Server.serve` for per-request context (e.g., user_id from authentication).
- Add `ssl_params` configuration option for Redis connections.
- Skip environment variable manipulation for streamable HTTP transport (thread-unsafe in multi-threaded servers).
- Use thread-safe data structures for session protocol version tracking.
- Remove dead code across the codebase.
- (Fix) Fix logdev references in server logger.
- (Fix) Ensure context hash keys are symbolized when retrieved from session.
