 SpaceIndices.jl Changelog
 =========================
 
+Version 1.1.0
+-------------
+
+- ![Enhancement][badge-enhancement] We now use the Celestrak file `SW-All.csv` to obtain
+  some space indices such as the F10.7, Ap, and Kp. We also removed the old files
+  `fluxtable.txt` and `Kp_ap_Ap_SN_F107_since_1932.txt`. Notice that this modification **is
+  not considered** to be breaking because all indices can be fetched using the same
+  functions (API). (PR [#2][gh-pr-2]))
+- ![Feature][badge-feature] We added some other indices available in `SW-All.csv`.
+  (PR [#2][gh-pr-2]))
