v2.7.0 Release

Changes

• [build] Switch to ESLint 9.x #470
• [diagram] Fix AbstractUIExtension error message #469
• [diagram] Fix edit label UI not resizing on graph zoom #455
• [mcp] Add Model Context Protocol client- and protocol-side support, paired with @eclipse-glsp/server-mcp #456
  • New optional mcpServer?: McpServerConfiguration field on InitializeParameters opts the GLSP server into starting an MCP server; the response carries an McpServerResult descriptor with the announced URL.
  • Configuration is split into init- and deploy-controllable parts (McpServerInitOptions / McpServerDeployOptions) so security-relevant fields stay under deployment control.
• [export] Generic, format-agnostic export pipeline #456
  • New RequestExportAction / ExportResultAction pair coexisting with the legacy RequestExportSvgAction / ExportSvgAction flow under strict separation.
  • Pluggable DiagramExporter registry with default SVG and PNG strategies and a shared post-processing step. PNG export is a new built-in capability.
  • Adopters register a custom DiagramExporter to add formats or override the defaults.
• [protocol] Move OriginViewportAction from the client package to @eclipse-glsp/protocol so it can be dispatched server-side as well. The action is still re-exported transitively via @eclipse-glsp/sprotty, so existing client-side imports continue to work. #456
• [protocol] Add bidirectional request/response protocol support for server-initiated queries #480
• [routing] Add sticky Manhattan edge router and rounded-corner edge view #486
• [example] Add standalone browser example running the GLSP workflow server as a web worker #490 #500
• [example] Update start scripts to support external bundles and configurable ports #506
• [api] Restore parallel-start dispatch for async action handlers #507
• [mcp] Make MCP server startup configurable via URL parameters #508

Potentially Breaking Changes

• [node] Update minimum requirements for Node to >=22 #476
• [protocol] Remove direct dependency on lodash #495
  • Base GLSP packages no longer depend on lodash. Adopters that relied on lodash being available transitively must either switch to the new GLSP utility functions or add lodash as a direct dependency.
• [protocol] OriginViewportAction.is now also requires the animate field (matching the shape of CenterAction.is and FitToScreenAction.is). Hand-rolled emitters that ship a bare {kind: 'originViewport'} will no longer pass the guard; use OriginViewportAction.create() (which defaults animate: true) or include animate explicitly. #456
• [protocol] GLSPClient.shutdownServer() now returns MaybePromise<void> instead of void. Pre-existing synchronous adopter implementations remain valid; callers that dispose the connection immediately after the shutdown signal MUST await the returned value to ensure the notification is flushed to the wire before the connection closes. #456
