We cannot bump the format during the 1.7.x series because 1.7.0 would not understand format N+1 produced by (say) 1.7.2. One thing that we could do: have 1.7.x "understand" all formats from 29 through 39. We only make changes that are both forward and backward compatible (e.g. presence/absence of an index does not affect 1.7.x from using the wc.db). For 1.8.0, we autobump to format 40 with our various changes. Cheers, -g
