 SpaceIndices.jl Changelog
 =========================
 
+Version 1.1.1
+-------------
+
+- ![Bugfix][badge-bugfix] We can now process the file `SW-All.csv` if there are invalid
+  lines. In those cases, the lines will be rejected. (Issue [#4][gh-issue-4])
+- ![Enhancement][badge-enhancement] We now use the Julian Day instead of `DateTime` as the
+  internal date representation. Notice that the public API has not changed. This
+  modification made SpaceIndices.jl compatible with automatic differentiation packages.
+  (PR [#3][gh-pr-3])
+- ![Info][badge-info] The Kp and Ap vectors returned by `space_index` are now `Vector`s
+  instead of `Tuple`s.
