We are pleased to announce ejabberd version 20.01. This release focuses on OAUTH support, logging performances improvement and configuration helper, as well as the usual various bug fixes.
New Features and improvements
We are now supporting OAUTH to authenticate with the embedded MQTT server.
This will only work for MQTT 5.0 connections. A client MUST set “Authentication Method” property of CONNECT packet to “X-OAUTH2” and MUST set the token in “Authentication Data” property of the same CONNECT packet. The server responses as usual with CONNACK.
On the server, you just have to enable OAUTH authentication like for XMPP, as described in the post about understanding ejabberd OAuth support.
We are now using the new logger introduced in OTP22, instead of lagger. This should greatly improve performance of the logging infrastructure.
A new configuration parser/validator was added, to check
ejabberd.yml syntax and find configuration issues.
The routine to convert password to SCRAM format now works for all backends, not only SQL.
We’ve started to add to support to use CockroachDB as database backend.
Database schema changes
To migrate from 19.09 to 20.01, you have to use the following commands on your existing database, after you’ve made a backup of it:
If you are using the legacy mysql.sql schema:
ALTER TABLE oauth_client CHANGE `client` `client_id` text PRIMARY KEY; ALTER TABLE oauth_client CHANGE `secret` `client_name` text NOT NULL;
If you are using the newer mysql.new.sql schema:
CREATE TABLE oauth_client ( client_id varchar(191) NOT NULL PRIMARY KEY, client_name text NOT NULL, grant_type text NOT NULL, options text NOT NULL
CREATE TABLE oauth_client ( client_id text PRIMARY KEY, client_name text NOT NULL, grant_type text NOT NULL, options text NOT NULL );
ALTER TABLE oauth_client RENAME COLUMN client TO client_id; ALTER TABLE oauth_client RENAME COLUMN secret TO client_name;
Download and install ejabberd 20.01
The source package and binary installers are available at ProcessOne. If you installed a previous version, there are no additional upgrade steps, but as a good practice, plase backup your data.
