JrNet Games Plugin 2.41 has just been released. This release fixes a serious bug in version 2.40 that stops users from playing games stored in archives. If version 2.40 is already installed a message to update will be shown on the next use of the plugin.
On a brighter note, the wizard for third-party publishers to use their games with the JrNet Games Plugin has been updated to allow the use of the new parameters feature in the 2.40/2.41 version of the JrNet Games Plugin.
