+                Bug Fixes
+              </h3>
+              <ul class="changes-list">
+                <li><strong>Diff view showing up on wrong lines.</strong> Fixed issue where diff view would appear on incorrect lines due to stale data in the editor. Added proper cleanup and state invalidation when editor content changes. <em>Files: <code>DiffView.tsx</code>, <code>EditorPane.tsx</code></em></li>
+                <li><strong>Model selector sluggishness.</strong> Reduced avoidable work in the compact selector by memoizing derived lists and selected model. Removed delayed/smooth scroll on open (which can feel laggy) and switched to <code>requestAnimationFrame</code> + instant nearest scroll. <em>Files: <code>CompactModelSelector.tsx</code></em></li>
+                <li><strong>History titles missing.</strong> Added a resilient fallback title strategy: use <code>conversation.title</code> if present, else use <code>preview</code>, else synthesize from last active timestamp (<code>Conversation X ago</code>). <em>Files: <code>HistoryTab.tsx</code></em></li>
+                <li><strong>Natural chat autoscroll + user can interrupt with wheel.</strong> Reworked autoscroll to use the real scroll container ref. Split behavior: scroll on new message if user is at bottom / just sent; during streaming, only keep following while user remains at bottom. This preserves manual scroll interruption. <em>Files: <code>ChatPanel.tsx</code></em></li>
+                <li><strong>Settings save feels slow.</strong> Changed save flow to close modal immediately, then persist in background. Keeps UI responsive while save + model refresh continue asynchronously. <em>Files: <code>SettingsModal.tsx</code></em></li>
+                <li><strong>General snappiness + launch flicker.</strong> Removed duplicate no-tab editor rendering path that could cause visual churn. Tightened startup flow to show window after first frame and fade out loading overlay immediately (no extra nested delays). <em>Files: <code>Layout.tsx</code>, <code>main.tsx</code></em></li>
+                <li><strong>Modernized title bar buttons.</strong> Updated window controls to compact rounded buttons with tighter spacing and better active feedback. <em>Files: <code>TitleBar.tsx</code></em></li>
+                <li><strong>Terminal too close to sidebar shadow.</strong> Increased left padding in terminal content area. <em>Files: <code>TerminalPane.tsx</code></em></li>
+                <li><strong>Fixed crash in read_file_range on out-of-bounds slice.</strong> Added bounds clamping to prevent panic when requesting lines beyond EOF (e.g., start_line: 350 on a 259-line file). Now returns safe empty output for extreme or inverted ranges instead of crashing.</li>
