What's new in ejabberd 16.09

Sep 27, 2016
  • Support for Elixir configuration file. It means it is possible to configure ejabberd using an Elixir script file instead of ejabberd YAML format.
  • Support XEP-0355 – Namespace Delegation
  • This allows to use an external entity to manage some of the server features. This XEP is working with Privileged Entity (XEP-0356).
  • Support XEP-0356 – Privileged Entity
  • This allows a component or any entity to have a “privileged” status. As a result, it can manage an entity roster on its behalf, send or receive stanzas in the name of the server. The main goal of XEP-0356 is to create an external, server agnostic, PEP service.

New in ejabberd 16.06 (Jul 2, 2016)

  • The big improvement in this release is a new Access Control List (ACL) infrastructure. ACL rules are used in ejabberd config file to define fine-grained access to ejabberd features.
  • In ejabberd 16.06, the ACL configuration has been much improved to make it both simpler to use and easier to read. Moreover, ACL and access rules are not mandatory anymore when configuring access restrictions for a feature or a module: You can just inline the user, for example, making small configuration much easier to setup properly.
  • To make you even more comfortable, our new code is still supporting the old syntax and you can mix old and new syntax. It means that you can still use your existing configuration file and that you can migrate incrementally, as needed.
  • Config:
  • New ACL infrastructure
  • Add shorter version of some common access rules definitions
  • Allow @ inside acl rules user, user_glob or user_regexp to pass both user and server

New in ejabberd 15.11 (Nov 20, 2015)

  • Improvements:
  • The commands join_cluster and leave_cluster do not depend on external scripts anymore. This makes operation simpler from user perspective and more portable across systems. The commands are supported on Microsoft Windows the same way as on Linux and OS X.
  • Adding a node to a cluster:
  • Suppose you have already configured ejabberd on one node named ejabberd@node1. Let’s create an additional node ejabberd@node2 and connect them together.
  • Copy the .erlang.cookie file from node1‘s home to node2‘s home.
  • Start node2 node, and join it to the cluster:
  • $ ejabberdctl start
  • $ ejabberdctl join_cluster 'ejabberd@node1'
  • $ ejabberdctl list_cluster
  • ejabberd@node1
  • ejabberd@node2
  • This enables ejabberd’s internal replications to be launched across all nodes so new node can start receiving messages from other nodes and be registered in the routing tables.
  • Removing a node from the cluster:
  • Suppose you have already configured ejabberd cluster with nodes named ejabberd@node1 and ejabberd@node2 and you want to remove node1 from the cluster.
  • You just needs to shut down node1. There is no specific delay for the cluster to figure out that the node is gone, the node is immediately removed from other router entries.
  • If the node node1 is started again, it’s immediately attached back to the cluster until it has been explicitly removed permanently from the cluster.
  • To permanently remove node1 from the cluster, just call leave_cluster command from anywhere in your cluster (either node1 or node2): $ ejabberdctl leave_cluster 'ejabberd@node1'
  • The removed node must be running while calling leave_cluster to make it permanently removed. It’s then immediately stopped.

  • Admin:
  • Do not rely on behaviour info when doing config validation, so that it can work with ejabberd binary installers
  • When passwords are scrammed, report check_password_hash cannot work
  • Fix problem with merging values from multiple config files

  • Both RPM and DEB now are using the improved post-install script which creates ejabberd user when installing as root. This let ejabberd running as user without any manual setup.
  • Windows installer now uses %USERPROFILE% to get path of user writable directory. We made numerous other fixes to that version, thanks to your feedback.

New in ejabberd 15.04 (Apr 25, 2015)

  • New features:
  • We integrated usefull contributions around groupchat (mod_admin_extra and mod_muc_admin) into ejabberd core. This means ejabberd admins get a new set of powerful ejabberdctl command and API they can rely on with standard ejabberd deployments.
  • Also made XEP-0033 Extended Stanza Addressing a default component. This is extremely useful to build chat service that uses adhoc chat mechanisms. It brings to ejabberd the ability to send messages to multiple recipients at once without using Multi User chat or pubsub. You can see a bit like email cc or bcc features. This allows to build extremely simple and lightweight multi party chat features.
  • Among new features, we now have a SQLite backend that can replace Mnesia for those who prefer as basic backend for small and simple standalone deployments.
  • Improvements:
  • We improved a lot of modules, added some major pubsub improvements, better RFC compliance, many bug fixes and small tweaks all over the place thanks to your feedback. The cluster script helpers have been improved to work in more situations.
  • Elixir:
  • We are still pushing Elixir integration further: this new version of ejabberd can be embedded in any Elixir application, for example in a Phoenix Web application. Here is a tutorial showing how it works.
  • PubSub:
  • PubSub improvements include code refactor, bug fixes, minor optimisations and removal of old mod_pubsub_odbc. mod_pubsub now uses db_type parameter like all other ejabberd modules.
  • NOTE: Users of old mod_pubsub_odbc will need to alter pubsub_node table changing the type attribute: set flat when it was flat_odbc, hometree when it was hometree_odbc, and pep when it was pep_odbc. Without this manual change in your database, the new mod_pubsub will not work.
  • R16B03-1 is now the minimal required Erlang/OTP version
  • SQLite support
  • Default db_type can be specified with global default_db option
  • Included mod_muc_admin, mod_admin_extra and mod_multicast modules
  • Removed ejabberd_http_poll
  • Pubsub improvements
  • Better RFC compliance
  • Several other bugfixes

New in ejabberd 15.03 (Mar 21, 2015)

  • Added fixes and some major improvements.
  • You can learn more about the changes and roadmap by meeting part of the team in upcoming ejabberd San Francisco Meetup.
  • New features:
  • Websocket - Websocket support is among the major new features introduced in this release. You can write speedy XMPP web clients. This web support has been tested on large deployments and is extremely fast, with very low latency.
  • Customizable session backends:
  • Introduced a new major feature to give more flexibility in the way sessions are managed in ejabberd. In the past, session were managed in Mnesia because it was the best compromise between speed, latency and scalability. However, ejabberd is deployed on a large variety of usage patterns and platform types and sizes. We thus have decided to provide more flexibility to accommodate with various use cases. For most deployments Mnesia is still the default choice and best backend to store sessions. For corporate deployments that need to get easy access to online users and status from other components, we provide a SQL backend for live sessions storage. Finally, if you want to avoid duplicating session across nodes to deploy a larger cluster, you can store your session information in a central, fast, in-memory backend like redis.
  • This improves scalability or flexibility depending on your platform type.
  • Security improvement: SCRAM support for SQL authentication backend
  • If you use the default ejabberd SQL authentication backend, you can now enable password encryption in the database using the standard SCRAM approach. We also provide a tool to migrate your existing authentication database to the new SCRAM secure scheme.
  • Development community and Elixir improvements:
  • ejabberd 15.03 is also the continuation of 15.02 in the way it simplifies the development and management of contributed modules. The community is growing with more code being contributed by third party developers. You can already find many modules contributed by the community. And now you can even install contributed modules without having developer skills or module compilation.
  • Interest around ejabberd has been accelerating with the introduction of Elixir. This release improves Elixir support. Moreover, you can now write ejabberd tests in Elixir and they are ran transparently with the rest of the test suite.
  • Package management:
  • This feature allows you to install easily ejabberd contributed module, with a simple command like:
  • $ ejabberdctl module_install modulename
  • You can find more details on this blog post: Easy installer and structure for ejabberd contributed modules
  • Simple add cluster command:
  • With our constant desire to simplify deployment we added a new ejabberdctl command to add a node in a cluster in a single command. Those who went to the process of setting up a cluster will certainly love this new command:
  • $ ejabberdctl join_cluster ejabberd@existingnode
  • More details here: Adding a node in a cluster
  • Changelog overview:
  • As a summary, here is the high level changelog:
  • Add support for WebSocket
  • Flexible session management with multiple backends: Mnesia/SQL/Redis or custom backend for session manager
  • Security improvement with SCRAM based password encryption in SQL authentication backends.
  • Package management for ejabberd contributed modules.
  • Improved Elixir experience
  • Automatic clustering scripts
  • Added missing index on database
  • Important updates on the documentation, with the launch of a new documentation site: docs.ejabberd.im
  • Several other bugfixes
  • MySQL database structure improvement:
  • We were missing an index on privacy list in the default MySQL schema. The database schema has been updated.
  • If you want to apply the changes on a running instance, here is the SQL command to issue:
  • CREATE INDEX i_privacy_list_data_id USING BTREE ON privacy_list_data(id);

New in ejabberd 2.0 RC1 (Jan 21, 2008)

  • Clustering and Architecture:
  • New front-end and back-end cluster architecture for better scalability and robustness. Back-end nodes are able to run a fully fault-tolerant XMPP router and services, but you can now deploy many front-end nodes to share the load without needing to synchronize any state with the back-ends.
  • All components now run in cluster mode (For example, Multi-User chat service and file transfer proxy).
  • New load balancing algorithm to support Multi-User chat and gateways clustering. More generally it supports any external component load balancing.
  • ejabberd watchdog to receive warning on suspicious resources consumption.
  • Traffic shapers are now supported on components. This protect ejabberd from components and gateways abuses.
  • Publish and Subscribe:
  • Complete rewrite of the PubSub module. The new PubSub module is plugin-based, allowing developers to create new nodes type. Any application can be plugged to ejabberd and can provide rich presence as a pubsub plugin.
  • Personal Eventing via Pubsub support (XEP-0163). This module is implemented as a PubSub service. It supports user mood (XEP-107), User Tune (XEP-118), user location (XEP-0080) or user avatar (XEP-0084) for example.
  • Server to Server (s2s):
  • More robust code with connection timeout implementation.
  • Support for multiple s2s connections per domain.
  • s2s whitelist and blacklist support.
  • s2s retrial interval.
  • LDAP:
  • Many enterprise-class enhancements such as better behaviour under heavy load.
  • Support for LDAP servers pool.
  • Simplified use of virtual hosting with LDAP with domain substitution in config.
  • Ability to match on several userid attibutes.
  • Multi-user chat:
  • Clustering and load balancing support.
  • Ability to define default room configuration in ejabberd config file.
  • Many anti abuse features have been added:
  • New ACL to limit the creation of persistent room to autorized users.
  • Ability to define the maximum number of users per room.
  • Limitation of the rate of message and presence packets.
  • Limitation of the maximum number of room a user can join at the same time.
  • File transfer:
  • XEP-0065 - Proxy65 file transfer proxy. The proxy can run in cluster mode.
  • Authentication:
  • PAM (Pluggable Authentication Modules) support on *nix systems.
  • External Authentication protocol is now fully documented.
  • Web client support:
  • XEP-0124 - BOSH support: BOSH (Bidirectional-streams Over Synchronous HTTP) was formerly known as "HTTP binding". It provides an efficient alternative to HTTP polling for scalable Web based chat solutions.
  • HTTP module can now serve static documents (with mod_http_fileserver). It is needed for high-performance Web2.0 chat / IM application. System administrators can now avoid using a proxy (like Apache) that handles much less simultaneous than ejabberd HTTP module.
  • Added limitations enforcement on HTTP poll and HTTP bind modules (bandwidth, packet size).
  • System administration:
  • XEP-0133 - Service administration support. System administrators can now perform lot of ejabberd related admin tasks from their XMPP client, through adhoc commands.
  • Dynamic log levels: Improved logging with more log levels. You can now change the loglevel at run time. No performance penalty is involved when less verbose levels are used.
  • Better command-line tool, with more options available.
  • Localization:
  • ejabberd is now available in 22 languages: Catalan, Chinese, Czech, Dutch, English, French, Galicia, German, Italian, Japanese, Polish, Portuguese, Portuguese (Brazil), Russian, Slovak, Spanish, Swedish, Thai, Turkish, Ukrainian, Vietnamese, Wallon.
  • Build and Installer:
  • Many launch script improvements.
  • New translations. The binary installer is now available in Chinese, Dutch, English, French, German, Spanish, Russian.
  • Makefile now implements uninstall command.
  • Full MacOSX compliance in Makefile.
  • Configure script is clever at finding libraries in unusual places.
  • Development API:
  • Several hooks have been added for module developers (most notably presence related hooks).
  • HTTP request handler to write HTTP based plugins.
  • Manage connections IP address.
  • Bugfixes:
  • ejabberd 2.0 also fixes numerous small bugs smile Read the full changelog for details.
