@masahi @Lunderberg Yeah I totally agree! Would you guys suggest more details like "improved vulkan backends on ..."? Thanks a lot!

Thank you @masahi for helping edit the description for Vulkan! It looks pretty nice to me :-)

Thanks @jiangjiajun for proofreading the PaddlePaddle-related text. Yep these commits were not there a month ago when we collected the initial changelog draft. Thanks to @vinx13, who acted swiftly and added these commits into both the release notes and the changelog today, these PRs you mentioned are included in the latest draft!

Does this mean we will update v0.8 branch again this week, I merged a new pull request this week early https://github.com/apache/tvm/pull/9428 ,  will this be in v0.8?

Better to replace "Vulkan backend" at the "major exciting experimental features" section with `Improved Vulkan backend", since the vk backend has been around for a long time by now.

Thanks @junrushao1994 !

There are 2 part I think we may need to fix

For the **Accepted RFCs** part, 
> `[RFC-0019] Add paddlePaddle frontend` 

it should be `[RFC-0019] Add PaddlePaddle frontend`, just a case problem

And for the **Frontends** part,
> **PaddlePaddle initial support #8645**


I have checked the v0.8 branch, there are 6 pull requests merged, we could list them all like others
https://github.com/apache/tvm/pull/8645 https://github.com/apache/tvm/pull/9126 https://github.com/apache/tvm/pull/9236 https://github.com/apache/tvm/pull/9283 https://github.com/apache/tvm/pull/9295 https://github.com/apache/tvm/pull/9370

Should we wait for PyTorch TVM PR https://github.com/apache/tvm/pull/8777? It should be merged soon.

@jiangjiajun Yes, we will update v0.8 branch and cut a release candidate on Nov 8, 2021. After the cut, we will ask the community and PMC members to test to release, and if there is no regression we will make the release official

Ok replaced with "Improved Vulkan backend" at the overview, and added unusually more details in "Codegen Backends and Runtime" to show off our vk capability.

 A critical bug fix in SPIRV codegen allows the Vulkan backend to produce correct outputs on more hardwares and drivers. Added support for querying device specific hardware parameters and capabilities, dynamic shapes, irregular ops such as sorting and NMS, UBO, fp16, and vectorization. We can now run complicated models like MaskRCNN on Vulkan end to end.

I have tested v0.8 release on microtvm physical hardware for Arduino and Zephyr platforms. It passes the tests for these hardware:
- **Zephyr**: qemu_x86, nrf5340dk_nrf5340_cpuapp, nucleo_l4r5zi, stm32f746g_disco, nucleo_f746zg
- **Arduino**: due
