 ## Change log
+
+- **1.2.4 — Feb 16, 2023**
+  - Changed functions `read_sw_nrlmsise00` and `get_sw` due to the space weather file changed from 'SW-ALL.txt' to 'SW-ALL.csv'
+  - Deleted the colored-progress bar for downloading space weather file, and use `wget` instead.
 - **1.2.3 — Jun 7, 2021**
  - Added atmospheric models **JB2008**
  - Changed the output of the result to an instance
