# Changelog

## v3.0.12
Updated on 2026-Apr-11
* FIXED: Added "unset LD_LIBRARY_PATH" line as a workaround due to the latest Entware binaries using the RUNPATH embedded library search path mechanism instead of the previous RPATH method.
* Miscellaneous code improvements in CLI menu navigation.

## v3.0.11
Updated on 2026-Feb-18
* NEW: Added code to support automatic add-on updates from AMTM.
