To celebrate leap day, we are happy to release ejabberd 16.02, which
mark huge leap for ejabberd both in terms of features and
improvements.

In terms of features, we see in this release the culmination of our
work in several areas:
– Support for flexible offline retrieval, aka XEP-0013
(http://www.xmpp.org/extensions/xep-0013.html). This is a big win for
mobile developers.
– Improvements on archiving, with Message Archive Management (MAM) now
supporting version 0.4.1 of the specifications.
– Full Elixir compliant packaging with the ability to deploy ejabberd
as an Hex.pm dependency from your own application. See ejabberd on
hex.pm: https://hex.pm/packages/ejabberd
– Performance improvement with faster and more memory efficient XML
parsing and TLS encryption.
– Better stream compression with the ability to enable stream
compression after SASL.
– Easier adoption of ejabberd with a new migration script from Prosody
XMPP servers.

As usual, this version is the product of a great community team work,
with special kudos to Holger, Alexey, Evgeny, Pawel, Christophe,
Badlop, Mickaël for their large contributions in this release.

That community effort is what makes ejabberd is such a popular
project, with 2260+ stars on Github, availability in most Linux
distributions and showing amazing number of downloads! Thank you all!
