+### Version 1.0.3
+* Reduced code size, maybe a lot depending on your configuration.
+* Improved support for Delta, SCARA, and COREXY kinematics.
+* Move parts of Configuration files to `Conditionals.h` and `SanityCheck.h`.
+* Clean up of temperature code.
+* Enhanced `G29` with improved grid bed leveling based on Roxy code. See documentation.
+* Various bugs fixed from 1.0.2.
+* EEPROM layout updated to `V17`.
+* Added `M204` travel acceleration options.
+* `M204` "`P`" parameter replaces "`S`." "`S`" retained for backward compatibility.
+* Support for more RAMPS-based boards.
+* Configurator utility under development.
+* `M404` "`N`" parameter replaced with "`W`." ("`N`" is for line numbers only).
+* Much cleanup of the code.
+* Improved support for Cyrillic and accented languages.
+* LCD controller knob acceleration.
+* Improved compatibility with various sensors, MAX6675 thermocouple.
+* Filament runout sensor support.
+* Filament width measurement support.
+* Support for TMC and L6470 stepper drivers.
+* Better support of G-Code `;` comments, `\`, `N` line numbers, and `*` checksums.
+* Moved GCode handling code into individual functions per-code.
 
+### Version 1.0.2
+* Progress bar for character-based LCD displays.
+
+### Version 1.0.1
+
+### Version 1.0.0
+* Initial release
