Spark is an Open Source, cross-platform IM client optimized for businesses and organizations.
It features built-in support for group chat, telephony integration, and strong security.
Spark was created around the same time that the Kyoto protocol went into effect, Pluto got demoted to the status of 'dwarf planet' and Italy won the FIFA world cup in Germany. Since then, source code development tooling has improved a lot.
Old users won't be affected by this (those upgrading straight from 2.7 version will still be affected).
Those who are using Client Control plugin will have to update it to version 2.1.0 as Spark 2.8.2 is already modified to work with that version and it will miss many menus and checkboxes if being used with an older version of that plugin. If you are using older version of Openfire and want to keep using Client Control, you might want to hold of updating to Spark 2.8.2.
We also would like to mention Spark Meet plugin provided by our long time contributor Dele Olajide.
For such users "Accept all certificates" setting will be disabled after updating to 2.8.2 from any version.
They will have to go to Advanced menu and enable it, if they encounter "Unable to verify a certificate" error.
