   <change-notes><![CDATA[
+        <h3>0.1.5</h3>
+        <h4>Added</h4>
+        <ul>
+            <li>Doctor diagnostics action — menu entry showing Ruby SDK, Gemfile, docscribe gem, daemon state, settings</li>
+            <li>Rakefile support (no extension) — all actions and annotations work on <code>Rakefile</code> files</li>
+            <li>Capability detection — docscribe version parsed on startup; server mode skipped for &lt; 1.5.1</li>
+            <li>Graceful handling when docscribe gem not installed — notification with &ldquo;Open Gemfile&rdquo; action</li>
+        </ul>
+        <h4>Changed</h4>
+        <ul>
+            <li><code>com.intellij.modules.ruby</code> made optional — plugin installs on IntelliJ IDEA (limited), unblocks Marketplace</li>
+            <li>All commands use project Ruby SDK — SDK <code>bin/</code> on <code>PATH</code>, <code>BUNDLE_GEMFILE</code> set</li>
+            <li>Concurrency guard for rapid annotations — per-file generation discards stale results</li>
+            <li>Annotation cache respects settings — <code>configHash</code> derived from <code>hideCommentsByDefault</code></li>
+            <li>Version bumped from <code>0.1.4</code> to <code>0.1.5</code></li>
+        </ul>
+        <h4>Fixed</h4>
+        <ul>
+            <li>Annotation cache not invalidated on settings change — added clear on save</li>
+        </ul>
+        <h4>Build</h4>
+        <ul>
+            <li><code>intellijDependencies()</code> added to repository section in <code>build.gradle.kts</code></li>
+        </ul>
