Joomla 1.0.10 introduced some new security features that now require users of the new version to upgrade their sites. These are mandatory upgrades.

MOD_LOGIN_JW

• Version 1.3.1 of mod_login_jw has been released. To avoid confusion, the module is named mod_login_jw_13. This is a mandatory upgrade for those using Joomla 1.0.10 and later ONLY. Do not use it on older versions of Joomla. Download the package and install it as any other module. Unpublish your old mod_login_jw and publish the new one in its place. Be sure to check the configuration parameters and change them to match your old module.
• If you already downloaded and installed version 1.3 of mod_login_jw (9 people did) you must download this new version once again. There was a bug in the first release of 1.3 that caused the "subscribe" button to appear instead of the "register" button on the first display of the page. In addtion, the registration link has been changed to link to the new registration component.
• This version also gives you a new configuration option to help integrate with vBulletin by emulating the vBridge login module. This feature should be used only for testing. It has  not been adequately tested to certify it for use on production sites. Please add your comments to the Third Party integration topics in the Support Forum. 

• Version 1.3.0 of com_jw_registraton_13 has been released. To avoid confusion with prior versions, the component name is also changed as noted, and will install as com_jw_registration_13. This is also a mandatory upgrade for those using Joomla 1.0.10 and later ONLY. Do not use it on older versions of Joomla.
• In addition to offering compatibility with Joomla 1.0.10 the new release integrates new Terms and Conditions functionality.
• To enable the new terms and conditions functions first create a "Static Content Item" using the content editor. Then open the JW Registration component configuration page and select "yes" to enable the function, and select which Static Content Item to display for the terms and conditions. Finally you will need to install and publish the new jw_termsbot.

JW_TERMSBOT

• JW_termsbot works together with the terms and conditions functions on your registration component. When you publish this bot, it will check if your user has agreed to the T&C. If they have not, it will display the T&C page to them once again. In fact once a user has logged in, they will be unable to do anything until they agree to the T&C.
