1.1.0

86f028c

1.1.0

Sync Gateway 1.1 packs in a number of significant enhancements, including:

A new integration mechanism: Webhooks. With this release, we are beginning to expose an event model to which you can add handlers. This makes it even easier to integate Couchbase Mobile with line of business applications, 3rd party services and apps, etc.
PouchDB compatibility. Extend your Couchbase Mobile user experience to your HTML5/JavaScript apps.
Cross-Origin Resource Sharing (CORS) support. Enable Sync Gateway to respond to HTTP requests that origin from one or more approved external websites.
Friendlier default configuration. Now when you run Sync Gateway without providing any configuration options, the Guest user will be enabled and will have access to all documents. The tradeoff, for security reasons, is that Sync Gateway will default to listening on the local loopback interface only.
Production certification for Couchbase 3.1, and non-production certification for using 4.0 (Beta 1). Sync Gateway users are encouraged to upgrade to 3.1 in order to take advantage of all the great improvements since the 2.5.2 release.
