• Fixes for fwupd dock firmware updates, openldap timeout behavior, dnsmasq reload crashes, samba GPO crashes, and gvfs encrypted partition mounting.

• This summary covers only packages in main and restricted; additional changes exist in universe and multiverse.
• Several kernel flavors received backported fixes; verify the correct flavor for your deployment before upgrading.
• Updated installation media are provided, so fresh installs should use the new images rather than 24.04.2 media.
