+## Notes on Version 1.2.0
+
+- Improved "--rewind_stars" option which iterates on the transformation fitting using Gaia-only (in the first iteration) and Gaia-HST (in subsequent iterations) PMs to provide better solutions.
+- Implemented "--load_existing" option which saves time by skipping the image checking procedure when the images have been previously downloaded.
+- Fixed bug: Gaia's positional uncertainties have been increased by default (Fabricius et al. 2021).
+
 ## Notes on Version 1.1.0
 
 - Fixed bug: GaiaHub will now not download HAP images.
-- New statistics added through the "---use_stat" option.
+- New statistics added through the "--use_stat" option.
 - New iterative sigma-clipped method to obtain the absolute reference frame.
