There are many dangerous changes in 4.2. At least I do not plan to upgrade to 4.3 any soon because of the compatibility issues.

It does not work now because before 4.2 tx_mllinks_pi1 would be added by addPItoST43() to system–wide "includeLibs". Now it is added to USER's includeLibs. Therefore if you do not call USER object before typolink's call, the needed class will not be loaded.

There are a lot of such small changes in 4.3, which make it dangerous for upgrades or for existing extensions.
