2026-04-09 - MCP tools with non-standard JSON schemas are now sanitized for compatibility with all model providers - Better handling of large images from MCP and extension tools - Improved rendering performance with a new simplified inline renderer - Show a clear message to contact your organization administrator when remote sessions are blocked by policy - Sub-agent activity no longer shows duplicated tool names (e.g. "view view the file...") - Permission checks and other hooks now work correctly when using Anthropic models via BYOM/BYOK configuration - Slash command picker appears above the text input for a more stable layout - Custom agents can now declare a skills field to eagerly load skill content into agent context at startup - Plugins can now display a post-install message with setup instructions after installation - Remove .vscode/mcp.json and .devcontainer/devcontainer.json as MCP server config sources; CLI now only reads .mcp.json. A migration hint appears when .vscode/mcp.json is detected without .mcp.json. - Plugins remain enabled across sessions and auto-install on startup based on user config - Add sub-agent depth and concurrency limits to prevent runaway agent spawning - Warn when resuming a session that is already in use by another CLI or application - CLI no longer crashes on systems affected by a V8 engine bug in grapheme segmentation - sessionStart and sessionEnd hooks fire once per session in interactive mode instead of once per prompt - Plugin agents respect the model specified in their frontmatter
