+## 1.1.2 - 2026-09-25
+
+- **fix: Steam's HDMI-CEC settings reach cecd on a first run**
+  - HDMI-CEC runs before Steam Machine support, which installs
+    steamos-manager; so steamos-manager's `configure-cecd` unit couldn't be
+    enabled and cecd ran without Steam's settings. Steam Machine support now
+    links them once steamos-manager is there.
+
+## 1.1.1 - 2026-09-25
+
+- **perf: Pinned kernel before the LED driver**
+  - With the kernel pin ticked, Steam Machine support installs kernel
+    7.1.6-1 first, so DKMS builds the LED driver once, for that kernel,
+    instead of for the current kernel first and then again. The LED driver
+    then loads after the restart, which it now says instead of warning.
+- **fix: steamos-manager starts after cecd**
+  - It checks only at its start whether cecd runs; if it was first, Steam's
+    HDMI-CEC settings were missing until it restarted. A drop-in
+    (`/etc/systemd/user/steamos-manager.service.d/`) orders it after cecd.
