    • lock the Dashboard completely: Editing/moving only becomes possible when unlocking the page

    • use tile title as index
  • webgui: fixes issue displaying Attributes when temperature display set to Fahrenheit.
  • zfs: fixes an issue importing ZFS pools with additional top-level sections besides the root section.

  • Add scheduled trimming of ZFS pools.
  • Replace the Scrub button with Clear button when the pool is in an error state.

To Upgrade

  • First create a backup of your USB flash boot device: Main/Flash/Flash Backup
  • If you are running any 6.4 or later release, click 'Check for Updates' on the Tools/Update OS page.
  • If you are running a pre-6.4 release, click 'Check for Updates' on the Plugins page.
  • If the above doesn't work, navigate to the Plugins/Install Plugin, copy/paste this plugin URL, and click Install:

Note regarding plugins: This release includes a PHP upgrade from v7.4 to v8.2.3, which is necessary for continued PHP security updates.

We recommend you upgrade all your plugins before updating the OS and be aware that any plugin which has yet to be updated recently (with a comment about PHP 8 in the change logs) may not work correctly.

You should consider uninstalling that plugin until the author has had time to update it. Plugin authors know the necessary changes, and many plugins have already been updated. If you encounter an issue with a plugin, please create a nice post in the appropriate support topic.
