+Subject: [PATCH 1/2] fix(image): treat missing interval as once
+
+PR #4390 enabled millisecond intervals but changed image interval parsing so a missing interval could resolve to 1ms. That creates a hot update loop and can spike CPU and destabilize rendering in drawer/group setups (issue #4835).
+
+Use explicit semantics: missing, null, non-numeric, or <=0 interval is treated as "once" (max sleep), while positive numeric values still support ms precision with a 1ms floor. This keeps the intended feature (sub-second polling when requested) without defaulting to busy looping.
+
+Also align waybar-image(5) docs with runtime behavior.

+Subject: [PATCH] systemd: declare known incompatible desktop environments
+
+Waybar can be used with many different Wayland compositors. Some of
+those provide distinct user session targets, some aren't. The usual
+recommendation for the latter ones is to allow manual startup of the
+graphical-session.target and run "systemd --user start ..." command on
+init.
+
+To ensure that all of the above is supported, we have to keep the
+service bound to the graphical-session.target. However, this may impact
+unrelated sessions on machines with multiple DEs installed.
+
+Instead of listing dozens of supported Wayland compositors and breaking
+any configs that explicitly use graphical-session.target, keep a list
+of known sessions where Waybar is not wanted.
