Subject [RELEASE] 2.1.1 & 1.7.0
Date Tue, 07 Nov 2017 16:58:46 GMT
Dear CouchDB Community,

The Apache CouchDB development team is proud to announce the
immediate availability of versions 2.1.1 and 1.7.0.

Both releases are security releases and fix multiple CRITICAL
issues. Updates are mandatory.

Due to the severity of the issues and the limited options for
workarounds, we will delay the release of detailed descriptions
by seven (7) days and publish a full report on Tuesday, November
14th. We expect all CouchDB users to update their installations
before then.

We are working with various package managers to ensure a smooth
update path, but we can not make any promises. We advise all
users to prepare to update from source, instructions can be
found in the CouchDB documentation: (2.1.1) and (1.7.0).

For download options, see the download section of the main CouchDB
