Interesting, 2025 was actually the most active year in sokol development (it didn't feel that way, but there were 3 big updates: compute-shaders in spring, resource-views in summer, and the initial Vulkan backend in winter - also a good number of easy-to-manage PRs, kudos to all contributors :)

I just merged support for dual-source-blending in sokol-gfx (needs to be behind a dynamic feature flag though). Also no sample yet to actually test the feature. More details in the changelog:
github.com/floooh/sokol...
Many thanks to GH user Tremus for providing the initial PR!

Surprised by the "underrepresentation" of China in the country graph (just 2%). When I was hanging around a Chinese mobile game company around 2017/18 I had the impression that Go is "big in China" for mobile game backends (e.g. Go server and Unity game client)

It's now possible to use the experimental sokol-gfx Vulkan backend on Windows:
github.com/floooh/sokol...
Still only tested on an Intel Meteor Lake embedded GPU. Interestingly RenderDoc works just fine with the Vulkan backend on Windows (it didn't on Linux).

Spent the last couple of days dogfooding by porting most of my hobby projects from 'fips' to 'fibs' (e.g. build files are now written in Typescript instead of a mix of cmake, python and yaml) - quite happy with it now.

I have been trying out many modern C alternatives (Rust, Zig, C3, Odin). Along the way I learned about arena allocators and decided to give C a second chance. The engine compiles natively and to WebAssembly. To test it out I have started building a silly little retro style boomer shooter.
