+## Changelog
+
+#### 2.0.2
+
+- Position of banner is moved from top to beneath "Input Power Control" heading
+- Some more delays are removed from debug script as I see unreliability in them
+- Link to Changelog is working now and banner also has been stretched to fit
+
+#### 2.0.0
+
+"Advanced Charging Control (ACControl)" is renamed to "Input Power Control (IPControl)"
+due to name clashes with "Advanced Charging Controller (acc)" by @VR-25. You are
+requested to uninstall any version of ACControl yourselves.
+
+- Unlikely to [--help], [-i] exits with success (0) instead of failure (1)
+- Sane sleep delay is reduced to 1 second, resulting in almost instant operations
+- Threads are now synchronized by sane sleep delay, so crashhes because of multi-
+  threaded model should vanish
+- Output of debug script now fits Termux' default window size and many others too
+- README files are garnished with banner designed and contributed by the awesome
+  Gaming_Inc @ Telegram
+- Control files preference order is updated to potentially fix 'level stuck at
+  disable threshold' reports
+- Errors not caused by IPControl are now displayed as 'Error occured while...'
+- Shorter delays are removed from debug script as they introduced unreliability
+- Effective UID is presumed root and is never seteuid(UID_ROOT) due to SELinux
+- Commandline now implements short options (with no GNU extensions) instead of
+  long ones
+- Unused symbols are stripped from binaries, thus greatly reducing binary sizes
+
+#### 1.3.1
+
+Intermediary versions from v1.1.1 to v1.3.1 are lost as I had to reset and setup
+my local development environment and personal testing device all over again.
+
+- Fix modules flashed after ACControl unable to mount magisk.img when ACControl
+  had aborted for some reason, applicable to Magisk v18.0 or lesser
+- Reduce sane sleep delays to 10 seconds, thus improving accuracy to great extent
+- Update documentations and make [--help] output fit Termux' default window size
+- Fix the daemon not being killed by `acc --daemon kill` and `acc --daemon launch`
+  spawning multiple daemons if subsequent calls were made to it
+- Fix the daemon recognizing a method as running after unreachable level was given
+  to [--method], thus no methods could be ran until a reboot
+
+#### 1.1.1
+
+- Update documentations
+
+#### 1.1.0
+
+- Remove all untested legacy-derived switches
+- Don't check each switch on initialization
+- Update debug script
+- Remove need of initializing on each install
+- Fix heavy resource usage for some devices
+
+#### 1.0.2
+
+- Fix 'Permission denied' errors when initializing
+
+#### 1.0.1
+
+- Add support for some new devices
+- Fix syntax error in debug script
+
+#### 1.0.0
+
+- Renamed from `Advanced Charging Switch`
