The current Neon image for my Mycroft MK2 is based on Debian Bookworm.
Debian Bookworm is what is know as the current testing version before being turned into the new stable Debian release (planned for June 10th 2023)
When I checked it, there were over 400 upgrades available from Debian on my RPI4.
I made an image just in case I had to restore stuff to a working situation and performed the upgrade.
Glad to mention everything still works, and with the memory leak of the alpha release gone, my mycroft seems more stable (lower load as well) than before.
