I think Freeway 7x has been very stable-- I’ve had only one crash this whole year and it was due to too many mouse clicks in a short period of time, an issue I’ve had with Freeway for the last two major versions.
I had an earlier issue with max-width only measurements on inflow items constantly reverting to fixed widths-- that seems to be fixed or less of an issue now. Sometimes a % width inflow items when copied/pasted either reverts to fixed width or adjusts to a different percent and must have the measurement reapplied.
I still have an issue with styles that are applied to a container on the master page using the Style Palette, on the child page they are impossible to undo. Also, changing the style of a container on the master does not reflect on the child item unless I uncheck/recheck the Use Master Setting.
Other seemingly small problems have been reported, but they might have already been addressed. They never bothered me. If you have good fonts/font management, this version has been very stable so far.
