This version sports an updated SDK which adds the ability to retrieve emails as per the latest Twitter policies; it should also be more stable as the 2.1 SDK is way outdated. Additionally, MyTwitter Connect 3.0 has been rewritten using the more known MyFacebook Connect as codebase, and it inherits some of its features such as continuous operational state and a separate login button template.
MyTwitter Connect now requires PHP's
OpenSSL, and PHP 5.4+. No support will be given to more outdated PHP versions.
Please do reckon that 3.0 is in pre-release state. No tests have been performed so far, and some things will likely change according to your feedbacks.
To update, delete the /mytwconnect/ folder first; then, upload the new files, overwriting the old ones, and run the upgrade script in the ACP when asked.
Please do a full backup of both your files and database before testing MyTwitter Connect 3.0.
