Release Notes

Supercell Wx v0.6.1 v0.6.1 is primarily a maintenance release: stability fixes, provider reliability, and distribution polish. There are no major new UI features. The main user-facing addition is a hosted Flatpak remote for Linux.

πŸ“¦ Flatpak Remote (Linux) Linux users can now install and update Supercell Wx from a hosted Flatpak remote instead of downloading a one-shot .flatpak bundle each release. After adding the remote, updates are handled with flatpak update. See the Flatpak setup guide for install instructions, including stable and nightly remotes. β€” @dpaulat (#670)
