What
When Claude Code's newer plugin-panel diff sidebar is available, it now checks whether your prior built-in diff sidebar was set to open or closed (the diffSidebarOpen setting) and opens in that same state, logging a message noting the preference was carried over.
Why
This means switching to the new plugin-based diff panel won't reset a preference you'd already set for whether the diff view stays open, so the panel behaves the way you're used to without extra reconfiguration.
