+WebGPU and wgpu-native are still changing fast, and with that we do to. We do
 not yet attempt to make things backwards compatible. Instead we try to
 be precise about tracking changes to the public API.

+### [v0.12.0] - 15-11-2023
 
-Changed:
-
-* The `wgpu.request_adapter()` is moved to `wgpu.gpu.request_adapter()`. Same for the async version.
-  This puts all API entrypoint stuff on the `wgpu.gpu` object, which also better reflects the WebGPU api.
-* The `rs` backend is renamed to `wgpu_native`.
-* It is no longer necessary to explicitly import the backend.
-* The `GPUDevice.request_device_tracing()` method is now a function in the `wgpu_native` backend.
-
-Added:
-
-* Convenience `auto` backend.
-* Stub `js_webgpu` backend.
-* New function `enumerate_adapters()` in the `wgpu_native` backend.
+This is a big release that contains many improvements, but also multiple API changes.
 
+Most backward incompatible changes are due to two things: the backend
+system has been refactored, making it simpler and future-proof. And we
+have revised the buffer mapping API, making it more similar to the
+WebGPU spec, and providing more flexible and performant ways to set
+buffer data.
 
-### [v0.11.0] - 11-10-2023
+A summary to help you update your code:
+```py
+# X import wgpu.backends.rs
+import wgpu
 
-Changed:
 
-* Update to wgpu-native 0.17.2.1. No changes are needed in downstream code.
+# X wgpu.request_adapter(canvas=None, power_preference="high-performance")
+wgpu.gpu.request_adapter(power_preference="high-performance")
 
+# X buffer.map_read()
+buffer.map("READ")
+buffer.read_mapped(...)
+buffer.read_mapped(...)
+buffer.unmap()
 
-### [v0.11.0] - t.b.d.
-
-We have revised the buffer mapping API, making it more similar to the
-WebGPU spec, and providing more flexible and performant ways to set
-buffer data.
+# X buffer.map_write()
+buffer.map("WRITE")
+buffer.write_mapped(data1, ...)
+buffer.write_mapped(data2, ...)
+buffer.unmap()
+```
 
 Added:
 
+* The `wgpu.gpu` object, which represents the API entrypoint. This makes the API more clear and more similar to the WebGPU API.
+* A convenience `auto` backend, and a stub `js_webgpu` backend.
+* New function `enumerate_adapters()` in the `wgpu_native` backend.
+* Warning about pip when wgpu-native binary is missing on Linux
 * The `GPUBuffer` has new methods `map()`, `map_async()`, `unmap()`. These have been
   part of the WebGPU spec for a long time, but we had an alternative API, until now.
 * The `GPUBuffer` has new methods `read_mapped()` and `write_mapped()`. These are not
   present in the WebGPU spec; they are the Pythonic alternative to `getMappedRange()`.
+* Flags can now be passed as strings, and can even be combined using "MAP_READ|COPY_DIST".
+* GUI events have an extra "timestamp" field, and wheel events an additional "buttons" field.
+* A diagnostics subsystem that amongst other things counts GPU objects. Try e.g. `wgpu.diagnostics.print_report()`.
+* Several improvements to the shadertoy util: offscreen support and a snapshot method.
 
 Changed:
 
 * Can create a buffer that is initially mapped: `device.create_buffer(..., mapped_at_creation=True)` is enabled again.
+* The `wgpu.request_adapter()` function is moved to `wgpu.gpu.request_adapter()`. Same for the async version.
+* The `canvas` argument of the `request_adapter()` function is now optional.
+* The `rs` backend is renamed to `wgpu_native`.
+* It is no longer necessary to explicitly import the backend.
+* The `GPUDevice.request_device_tracing()` method is now a function in the `wgpu_native` backend.
+* We no longer force using Vulkan on Windows. For now wgpu-native still prefers Vulkan over D3D12.
+* The `wgpu.utils` subpackage is imported by default, but most submodules are not. This means that `compute_with_buffers` must be explicitly imported from `wgpu.utils.compute`.
 
-Removed:
+Deprecated:
 
+* `wgpu.request_adapter()` and its async version. Use `wgpu.gpu.request_adapter()` instead.
 * The `GPUBuffer` methods `map_read()`and `map_write()` are deprecated, in favor of `map()`, `unmap()`, `read_mapped()` and `write_mapped()`.
 
-For the record, these are not changed:
+To be clear, these are not changed:
 
-* The convenient `device.create_buffer_with_data()` (not part of the WebGPU spec) is also available.
+* The convenient `device.create_buffer_with_data()` (not part of the WebGPU spec) is still available.
 * The `GPUQueue.read_buffer()` and `GPUQueue.write_buffer()` methods are unchanged.
 
+Fixed:
+
+* The shaderutil now re-uses the default device, avoiding memoryleaks when running multiple consecutively.
+* The GUI backend selection takes into account whether a backend module is already imported.
+* The offscreen GUI backend no longer uses asyncio (it does not need an event loop).
+* Prevent a few classes of memoryleaks. Mind that creating many `GPUDevice` objects still leaks.
