I hope you've seen this Nostr Riga talk - nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s sings your praises "the only reason nostr works today is because of strfry"
YOU LEGEND DOUG!!
Exporting and importing events into a new strfry instance (which you need to do when the DB version changes) takes too long. Here's a feature I just added that speeds this up a lot:

Going forward, there is a release-0.9 branch. I'm going to tag one more release on that branch soon (after back-porting a couple fixes). It will have strfry export --fried but not import. I'm planning on this being the last release of the 0.9 series.
I'm working on a 1.0 release in the next branch. I just did a big refactor of the DB format that I've wanted to do for some time. I also removed prefix matching on id/pubkey (this was removed from NIP-01) and fixed a bunch of bugs. This release will also have the latest negentropy protocol version and BTree code.
