That isn't happening, mazmazz himself has said it's stuck on 2.2.4 for a long time (for school reasons). There is literately no point in using the web port anymore, just use the Android port now. Plus you can add controls and make seperate layouts properly along with being able to play at higher resolutions without joystick problems. Please, stop whining for a web port update people.
Fine by me tbh. Can still use a majority of the mods I typically use (with the exception being Modern Sonic v5.11, whenever I use that mod in-game he just appears green and can't use his custom moveset) and for getting through Google Meet calls with my school that's good enough for me.
It's also the only version I can use since my school blocked app store and apk installing on my chromebook so i'm stuck using web. But it still feels like SRB2 v2.2, just at a lower resolution, which I can work with.
