 - There is a new module for the `thunar` program (the Xfce file manager), which depends on the `xfconf` dbus service, and also has a dbus service and a systemd unit. The option `services.xserver.desktopManager.xfce.thunarPlugins` has been renamed to `programs.thunar.plugins`, and in a future release it may be removed.

+# ModemManager tends to interfere with USB Serial devices like Teensy.
+# Problems manifest as the Arduino Serial Monitor missing some incoming

+# uploading.  If you experience these problems, disable or remove
+# ModemManager from your system.  If you must use a modem, perhaps
+# try disabling the "MM_FILTER_RULE_TTY_ACM_INTERFACE" ModemManager
+# rule.  Changing ModemManager's filter policy from "strict" to "default"
+# may also help.  But if you don't use a modem, completely removing
+# the troublesome ModemManager is the most effective solution.
