-All internal CSS class prefixes have been changed to prevent style conflicts across minor versions. While this is not considered a breaking change according to our [support policy](https://github.com/iTwin/iTwinUI/wiki/Support-policy), this change might affect you if you ignore our pleas to not rely on these internal class names. The recommendation is to pass your own custom `className` through props.

 # Changelog
 
+## 3.13.0
+
+### Minor Changes
+
+- [#2106](https://github.com/iTwin/iTwinUI/pull/2106): All internal CSS class prefixes have been changed to prevent style conflicts across minor versions.
+  - While this is _not_ considered a breaking change according to our [support policy](https://github.com/iTwin/iTwinUI/wiki/Support-policy), this change might affect you if you ignore our pleas to not rely on these internal class names. The recommendation is to pass your own custom `className` through props.
+
+- [#2131](https://github.com/iTwin/iTwinUI/pull/2131): Development-only warnings will now be properly excluded from the production build. This is done using a separate `"development"` entrypoint listed in `package.json#exports`.
+
+- [#2135](https://github.com/iTwin/iTwinUI/pull/2135): Changed the column manager from a `DropdownMenu` to a `Popover` to fix invalid markup and accessibility issues.
+
+- Added dependency on `@tanstack/react-virtual` to replace the custom virtual-scroll implementation. This affects the `enableVirtualization` prop in `ComboBox`, `Table`, and `Tree`.
+  - [#2061](https://github.com/iTwin/iTwinUI/pull/2061): Virtualized `ComboBox` now correctly supports dynamic sizing, e.g. when options both with and without `subLabel` are present.
+  - [#2092](https://github.com/iTwin/iTwinUI/pull/2092): Virtualized `Table` has been improved so that scrolling no longer jumps when rows are scrolled past.
+  - [#2139](https://github.com/iTwin/iTwinUI/pull/2139): Virtualized `Tree` no longer requires a wrapping scrollable element, since the tree itself is scrollable now.
+    <details>
+      <summary>Diff</summary>
+
+      ```diff
+      - <div style={{overflow: 'auto', height: 'min(400px, 90vh)'}}>
