New Revision: 8267
URL: http://svn.mirrorbrain.org/viewvc/mirrorbrain?rev=8267&view=rev
Log:
mb:
- add ipv6_only, a new flag, to the server table. Not used yet.
- implement a way to migrate the database when needed, after updates. A table
"version" keeps info about the state of the database. For now, we do only
one migration (2.17.0) so we don't actually check for versions yet.
