It's the first release of 2019, filling in a few gaps before we get down to work on the next major release due in the summer.
Amazon Web Services has become a key platform for us over the past year. For customers hosted on the platform we're pleased to announce a new integration with Amazon Simple Email Service, which gives the advantage of spam and virus filtering on incoming email for a small additional monthly charge. We also added new spam filtering options in the product, letting you decide how to handle messages that are potential spam.
11.6 also has a handful of smaller improvements and fixes, including simpler configuration when running in a distributed server environment.
