Tips for TYPO3 Version 4.7

Version 4.7 brings innovations in the area of accessibility and support for HTML5. The generated HTML code now corresponds to the selected doctype.

Some program functions that were already marked as obsolete in previous versions have been removed from the code. These include the t3lib_htmlmail function, which was previously responsible for sending emails (contact form, registration, etc.).

While in versions 4.5 and 4.6 it was still possible to switch back to the old mail functions via the install tool (substituteOldMailApi), the htmlmail call can no longer be used.

In the TYPO3 Wiki there is a list of extensions that are not compatible with version 4.7.
