Prominent new features of the GNOME Builder 3.22.2 release include significant improvements to Flatpak support by allowing developers to target a Flatpak runtime when building their project, more RTL (Right-to-Left) improvements, as well as better Vim support with support for counting change operations. Additionally, users will find support for the Cargo and Meson build systems, the editorconfig component received runtime and build improvements, the Alt+0..n keyboard shortcut is now properly handled during auto-completion, and the json-glib-1.0 library is now an explicit dependency of GNOME Builder.
