Over the weekend of August 7th–8th, 2010 we discovered and fixed a nasty bug in CouchDB 1.0.0. There is potential data-loss for users of 1.0.0, running with the default configuration of delayed_commits=true.
We've issued an in-place fix and details about the data loss bug here: http://couchdb.apache.org/notice/1.0.1.html The 1.0.1 release will make a permanent fix, but in the mean time, following these instructions will ensure your data is safe. Chris
