+### Fixed
+- x86 live session: booting from a stick without a `syncphony-data`
+  partition no longer stalls on a missing `/data` device and then fails
+  SSH and the kiosk (`mkdir: cannot create directory '/data/chromium'`).
+  `/data` is the stick's partition when there is one, and RAM otherwise.
+- x86: the setup hotspot never appeared, because the image had no
+  `wpasupplicant` (NetworkManager only recommends it), so NetworkManager
+  couldn't scan or run an access point. It also gains `wireless-regdb`
+  and MediaTek and Broadcom Wi-Fi firmware.

 ### Changed
 - The image is smaller: documentation, man pages and translations are
   stripped (copyright files stay).
