TG4:19 had amendments predominantly in relation to the orientation of ring bolts where current thinking is that settlement is probably greater than side wind loads so reduces potential shear loads on the bolt. Other minor changes were cosmetic. A recent update in April 2019 saw the removal of one reference only when the guidance was reissued as TG4:19.
A temporary roof or building is a sheeted structure designed to protect the area inside from the effects of weather, dust, etc. This guide is intended to give design and construction information to the suppliers and erectors of temporary roofs and buildings and intended for use by contractors during the building process.
This guidance gives details of various products available which will satisfactorily hold down scaffold boards to prevent movement. Users should satisfy themselves that any proprietary system meets their requirements.

Scaffold board nail plates are specially stamped toothed strips of galvanised steel that can be used to help prevent scaffold boards developing splits, or in repairing scaffold boards that have split. This guidance gives details on the manufacture and installation of Nail Plates.
