Notes:

NOTICE!: Due to a bug in SMF 2.1.3 upgrading TinyPortal may result in this error message: "All parts of a PRIMARY KEY must be NOT NULL; if you need NULL in a key, use UNIQUE instead". In order to update TinyPortal while on SMF 2.1.3 you may need to install the [correction MOD that can be downloaded from the TinyPortal.net support site](https://www.tinyportal.net/index.php?action=tportal;sa=download;dl=item177). After applying this MOD you will be able to re-install TinyPortal on SMF 2.1.3. Please note that the correction MOD should be uninstalled prior to patching SMF to version 2.1.4.

This version contains an update of the internal block variable handling: after this upgrade there is no returning to TinyPortal versions before 2.3.0 while keeping the existing blocks intact!
