**v2020.10.14 (202010140)**

- acc -i: show additional power supply info, if any.
- build.sh: copy uninstaller to build dir.
- cooldown_current: instead of pausing charging periodically during the cooldown phase, lower the charging current (0mA or custom). This is the default behavior (smoother).
- Fetch current and voltage control files only once per boot session to prevent loss of default values.
- Fixed daemon restart/stop timeout issues.
- Fixed Zygote-related issue that prevented accd initialization on boot.
- Misc fixes & optimizations
- MTK switch delay ranges from 5 to 20 seconds.

 ## LATEST CHANGES
 
 
-**v2020.9.24 (202009240)**
-
-- Cooldown no longer interferes with capacity_sync.
-- Delay accd initialization (5 minutes) to prevent conflicts with fbind.
-- Do not auto-shutdown if charging was disabled by accd itself at temp >= max_temp.
-- Do not remount / rw if it's not tmpfs.
-- Fixed cooldown_custom.
-- Major optimizations
-- MTK and Razer specific tweaks
-- New charging switch for Motorola One Vision
-- Removed obsolete features.
-- Simplified config.
-- Updated documentation.
-
-Release Notes
-
-- Config will be reset.
-- MIUI bootloop issue possibly fixed.
