The list of all stable and officially approved plugins can be found at the dedicated page on the official web site of the project.
When you've got the archive with an actual version of a plugin you should extract files from it and upload them to the Mibew Messenger's web server replacing the old version of a plugin.
It is highly recommended to backup old files before replacement.
After update of the plugin's files, the database should be updated too. To do
so you should navigate to
<mibew base URL>/operator/plugin page and click on
'update' link in the plugin's row.

If the plugin was updated successfully the value in 'state' column will change to 'working'. If it did not, one should check the error log of the web server for details of the problem.
