What changed
Version 4.0.0 rebuilt the VS Code extension on the Cline SDK, adding the ClinePass provider, a Customize marketplace for Skills, MCP servers and Plugins, queued prompts and editing earlier messages; it also turned command auto-approval off by default and temporarily disabled subagents. On June 28, 4.0.1 restored the 3.89.2 code under the higher version number to fix regressions, while SDK work continued separately.
Who it affects
Cline VS Code extension users who updated in late June 2026.
What to do
Make sure you’re on 4.0.1 or later, and don’t expect the 4.0.0 features until the staged SDK rollout reaches you.
