📦 Latest MV2 Extensions

This list features soon-to-be-obsolete MV2 extensions, sorted from highest to lowest installed base. Although MV2 technology is about to become obsolete, the extensions in the list still provide reference value for developers, especially when looking for migration or optimization opportunities. Emulating the functional design of these extensions is a low-barrier-to-market option. However, developers need to do sufficient market research before attempting to develop similar products to assess whether there are unmet needs, while avoiding the risk of technological obsolescence during the transition period.
