Compatibility Plugin

As part of Joomla! 5.0 a plugin was introduced which enhance backward compatibility between Joomla 5 and 4. The plugin is implemented as "Behaviour" plugin type to guarantee that is loaded before any other plugin is loaded. (Just a heads-up, don't create a plugin as behaviour plugin because it's possible that this group get removed at some point)

The Joomla 5.0 version of the plugin includes 3 options which can separately can be activated by the Super User.

  1. Load legacy class name aliases.
  2. Load es5 webassets shim.
  3. Load removed webassets shim.

After upgrading Joomla! 4.4 to 5.0 this plugin gets automatically enabled and all options are active. On new installations for 5.0 and maybe later the plugin and it's options are enabled too.

Having the plugin active should allow a seamless update from Joomla 4 and allow to install not update Joomla extensions to be installed in Joomla 5. This gives extension developers or own developments additional 2 years time to update old code to the current standard.

Starting with Joomla 6 it's planned that deprecated code get removed finally. Especially for code provided by this plugin.

Why should you try to disable the plugin?​

The plugin loads additional code which impacts page load times. The numbers for the options are:

  1. More than 500 php function calls for each request
  2. Loading more than 1000 lines of JSON data and analyse it for each request
  3. Compared to the other 2 options we only have 15 lines of JSON data

You should be properly safe to disable option 2 and 3, because they are only relevant if an extension loads a legacy webasset directly which is unlikely.

For the first option it's more tricky because the class aliases which are provided here did exist since Joomla 1.0 but get deprecated and replaced starting with Joomla 3.3 around 2014 and continued to be filled till 3.10. The reason for the renaming of the classes was part of the move of Joomla to namespaces.

Recover in case the plugin has been disabled

If you disabled the plugin by accident or by try and get a php error you have to re-enable the plugin in the database again. This can be achieved by editing the enabled column in the #__extensions table for the row with the name plg_behaviour_compat and set it to 1.

We are urging extension developers to test there extension with the compat plugin disabled.

Disabling the compatibility plugin

Please do not disable this plugin on your production page, please try to disable the plugin on a test copy first. Make sure you have access to the db. That way, you can enable the plugin again quickly if needed.

Webassets es5 entries​

The es5 entries has been removed in 5.0 since no browser which doesn't support es6+ is maintained any more. The way our Webassetmanager works doesn't allow us to simply remove assets. For this reason we have all es5 entries moved to the b/c plugin and provide an empty dummy entry.
