In decky settings (gear icon) you can select "prerelease" for update channel and then "testing" for store channel. This should then let you update your plugins to newer versions of plugins that have fixes for the SteamOS changes that shipped to stable today. Worked for me at least.
ah ok, i just get worried about how things operate since I am new to linux lol. I wasn't sure if it rebooted like pushing a reset button on the pc case or like clicking restart from the application launcher. I read that there could be data loss?
