Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

GPU synchronization in Godot 4.3 is getting a major upgrade
Pipelines (or in general terms PSOs) are the most problematic aspect of Vulkan / DX12 - much more than synchronization! Large parts of the gamedev industry seems to recognize all the performance issues with pipelines and therefore companies are experimenting with newer models like the VK_EXT_shader_object extension ("Vulkan without Pipelines": https://www.khronos.org/blog/you-can-use-vulkan-without-pipe...).
I've written a detailed comment about this before here (https://news.ycombinator.com/item?id=37843946#37845431) but for a much more comprehensive explanation by an engineer from Nintendo read the initial proposal for the VK_EXT_shader_object extension: https://github.com/KhronosGroup/Vulkan-Docs/blob/main/propos...).
There's also Casey Muratori's mail to the Vulkan advisory on 2015 that basically predicts this whole clusterfuck would happen: https://github.com/cmuratori/misc/blob/main/vulkan_dynamic_s...

The Clean Code Debacle and Rhetoric Tricks - Casey Muratori vs Mr "Uncle Bob" Martin
I'll put the link to Casey and Uncle Bob's discussion about architecture here again. This discussion is specifically about maintainability. In it they both come up with a design for a device IO API, and argue its strengths in terms maintainability and extensibility.

New Vulkan Documentation Website
Apple -> MoltenVK is an emulation layer and doesn't give you as much control as using Metal directly.
Nintendo and Sony prefer their own APIs, NVN and LibGNM, and AIUI Vulkan is a second-class API on those platforms which does not offer as much power, it is widely understood studios use NVN and LibGNM to get access to the real hardware on those platforms.
Windows/AMD/NVidia/Intel -> HW manufacturers tend to prototype and release new features with D3D first and then 'backport' them to Vulkan after a while. DirectX 12 for example had mesh shaders for over 2 years before Vulkan got a vendor neutral extension for them[0]
Android and Linux are the only platform where Vulkan is a first-class citizen.
You could maybe argue Nvidia treats Vulkan as a first-class citizen because they tend to have vendor-specific Vulkan extensions for the latest features available before anyone else. But otherwise, no, Vulkan is not a first-class API anywhere except Linux and Android.
Graphics API wars are alive and well.
