Subject Re: [jira] [Commented] (COUCHDB-1346) CouchDB hangs during start of view indexing
Date Tue, 11 Dec 2012 04:46:33 GMT
Maybe because its not very clear what stage the release is at, where the pre builds are, etc.
 We have tested many oss pre-releases from distros like ubuntu, fedora to dbs like postgres,mongo
to apps like inkscape, etc but with couch we are confused - are we at beta, rc ?  Is it at
master or branch ?  Is cors in?   We are not sure what exactly we are supposed to test - maybe
we are missing blog posts or something?  It all just seems somewhat unstructured for something
that requires so much effort to upgrade as a db
