+v39.0 - 2023-11-15:
+  Tracing service and probes:
     * Added reporting of TZ offset under system_info.timezone_off_mins .
     * Added no_flush option to DataSourceDescriptor to avoid unnecessary IPC
       roundtrips to flush data sources like track_event that rely uniquely on
       server-side scraping.
+    * Added support for running on Linux & Android systems configured with 16K
+      pagetables.
   Trace Processor:
-    *
+    * New android_boot metric.
+    * Added new PerfettoSQL syntax (CREATE PERFETTO VIEW) for adding schemas to views.
+    * Support perf.data import format.
+    * Add dvfs and cpu_idle to stdlib.
   UI:
     * Add a new type of debug tracks: counter.
-  SDK:
-    *
+    * Improved visualization of timestamps for durations.

+#### Hotkeys
+
+A default hotkey may be provided when registering a command.
+
+```typescript
+ctx.registerCommand({
+  id: 'dev.perfetto.ExampleSimpleCommand#LogHelloWorld',
+  name: 'Log "Hello, World!"',
+  callback: () => console.log('Hello, World!'),
+  defaultHotkey: 'Shift+H',
+});
+```
+
+Even though the hotkey is a string, it's format checked at compile time using 
+typescript's [template literal types](https://www.typescriptlang.org/docs/handbook/2/template-literal-types.html).
+
+See [hotkey.ts](https://cs.android.com/android/platform/superproject/main/+/main:external/perfetto/ui/src/base/hotkeys.ts)
+for more details on how the hotkey syntax works, and for the available keys and
+modifiers.
