New versions of the G3v2 (version 2.7) and G4 (version 1.2) technical guides have been published for the G4 temporary storage declaration and presentation of goods to customs.

The main change is the limitation of the PreviousDocument group declaration to knowledge and the change to conditional (previously it was mandatory) of the reference of the previous document depending on the type of document. Some clarifications on validations, removal of a description of an illegal declarative flow, and several typo corrections are provided. See version control for more details.

Please note that for the air environment, the closing date for DSDT (Download Summaries) has been set at 01/15/2026.
