+Subject: [PATCH] build: Relax the version constraint for wlroots to accept
+ patch releases
+
+Patch releases only contain backwards compatible changes (mainly bug
+fixes) so we want to allow them. This fixes the build with the recently
+released wlroots 0.15.1 and uses the same version constraints as other
+projects that depend on wlroots (e.g., Sway).
