ejabberd 16.04

This new ejabberd release includes bugfixes, and also two major source code refactorings: one for ejabberd commands, and other for database specific code in many modules. This version is doing lot of under the scene changes to prepare further improvements and refactoring.

For consistency, modules configured to use an SQL RDBMS are named sql instead of the more confusing odbc. You are not required to modify your configuration file, old style ‘odbc’ keyword works, but you may want to update it and replace ‘odbc’ with ‘sql’.

We have also introduced a straightforward and new way for developers to add data / backend modules. If a developer need to add backend mystore to module mod_example, they only need to create mod_example_mystore, implement it with behaviour mod_example and add db_type: mystore in configuration of that module.

Erlang/OTP 18.3 is now used in all official installers and packages available in the download area.

  1. Hi, Im trying to use ejabberd hex package and its contains a dependency to stringprep-1.0.3 in hex.pm packages. When compiling stringprep it raises an error in windows. The console log is as follows:

You can recompile this dependency with “mix deps.compile stringprep”, update it with “mix deps.update stringprep” or clean it with “mix deps.clean stringprep”

    Please help me.

      • Hi thanks for your suggestion, the fact is that Im trying to use ejabberd in elixir. When I make a `mix deps.get`, ejabberd is a dependency of my project and stringprep is a dependency of ejabberd. In the compile step `mix compile`, mix try to compile every fetched dependencies, including stringprep. I don’t know how to bypass this step.

    • I set up phoenex in Ubuntu and configured my project to work with ejabberd. It download fine all dependencies and compile, but starting the server it throw an error:

      mix phoenix.server
      [info] Ignoring ejabberd logger options, using Elixir Logger.
