+# 0.2.30
+
+## Features
+
+- A new plugin install suggestion appears above the prompt when you type a known marketplace plugin name or domain.
+
+## Bug Fixes
+
+- **Trace uploads** and remote session restores now succeed with a deployment key and no browser login.
+- **Resumed sessions** no longer pad the sticky prompt with empty rows; cancelling a turn now keeps the rest of the prompt queue intact.
+- Cancelling a running prompt no longer leaves the interface stuck on the cancelling spinner.
