DDNet 15.2.4 will be a small bugfix release supposed to release in 1 day, assuming no bad bugs are found. Please test Release Candidate 1 to prevent problems being only discovered after release. Report bugs in the #bugs channel or directly on Github: https://github.com/ddnet/ddnet/issues/
You can also test the release candidate in Steam by clicking on Settings -> Properties -> Betas and opting into the Release Candidates. This will automatically update you to a new release candidate when it is available, and to the next release when no new candidate is available. So you can always leave this setting enabled to help us test new releases earlier.
This change fixes small ingame lags caused by the automatic skin downloader, so please test this specifically. But just playing as you do normally also helps.(edited)
