This operation decreases the size of the installation package while increasing the packing time. However, developers are more sensitive to the packing time in the development and debugging phase. As such, the packing tool is changed to pack **libs** in uncompressed mode by default. 12e41f4b71Sopenharmony_ci 13e41f4b71Sopenharmony_ci**Change Impact** 14e41f4b71Sopenharmony_ci 15e41f4b71Sopenharmony_ciThis change is a compatible change.
