Migrating from GRASS GIS 7 to version 8.x

With the addition of semantic labels, the temporal database was modified to version 3 and hence, to be able to read and process GRASS 7.x space-time datasets, users will be prompted to run G82:t.upgrade. If users want to read space-time datasets newly created in GRASS 8 back in GRASS 7.x, they can run G78:t.downgrade.
