Most stable version for CCR?

Hello,

is there an insider tip which is the most stable version for a CCR1009?
Especially the current 6.47.x versions are, at least here, not very stable. Mostly after 20 - 30 days
the router needed a restart. Since I don’t need any of the latest features and only have
a simple setup I could use a slightly older version.
As stable I would call an uptime of 100 days upwards.
Do you have a “secret tip”?

I suggest 6.45.9 (Long-term) as the most stable version.

Concur, that is the one I am using on my CCR and will stick based on experience to the long term versions
