+Files under /etc/bash/bashrc.d must now have a suffix of .sh or .bash.
+
+Gentoo now defaults to defining PROMPT_COMMAND as an array. Depending on the
+characteristics of the operating environment, it may contain a command to set
+the terminal's window title. Those who were already choosing to customise the
+PROMPT_COMMAND variable are now advised to append their commands like so:
+
+PROMPT_COMMAND+=('custom command goes here')
+
+Gentoo no longer defaults to having bash set the window title in the case
+that the terminal is controlled by sshd(8), unless screen is launched on the
+remote side or the terminal reliably supports saving and restoring the title
+(as alacritty, foot and tmux do). Those wanting for the title to be set
+regardless may adjust ~/.bashrc - or create a custom /etc/bash/bashrc.d
+drop-in - to set PROMPT_COMMMAND like so:
+
+PROMPT_COMMAND=(genfun_set_win_title)
+
+Those who would prefer for bash never to interfere with the window title may
+now opt out of the default title setting behaviour, either with the "unset -v
+PROMPT_COMMAND" command or by re-defining PROMPT_COMMAND as desired.
