Release Notes

2.0.0 (BigCouch 0.4.0)

Major changes since version 1.6.1 include:

• Allow creation and deletion of databases when a node is down.

• Wait for read repair before responding to the client. See commit 0b59b5 for more details.

• Modify get_missing_revs to return possible ancestor revisions. Needed to support the _revs_diff endpoint (and the replicator in the upcoming 1.2 release of Apache CouchDB, which uses that endpoint).

• Modify the clustered update sequence so that it sorts correctly. This improves replication checkpointing.

• Improve detection of errors during request processing by uniformly processing rexi_DOWN and rexi_EXIT errors.

• Reply 'accepted' instead of 'ok' if a document is written but we fail to meet the requested quorum. The HTTP layer will translate this into a 202 status code in the case of a single-document PUT request.

• Fix a few classes of timeouts and hangs when subscribing to continuous _changes feeds, especially when filters are applied.

• Use a simple majority as the default quorum.

• Handle missing docs when using "linked documents", and support requests to link against a specific revision.

• Support stale=update_after in view queries.

• Fail gracefully on _security if database is missing
