 # History
 
+## 2.0.0 (2020-05-16)
+
+### Breaking changes
+
+- The `Row.lpush/rpush` logic was reversed. `lpush` was appending while `rpush`
+  and `append` were prepending. This was fixed (reversed behavior). If you
+  counted on the broken behavior, please update your code (#453).
+
+### Bugfixes
+
+- Fixed minimal openpyxl dependency version to 2.6.0 (#457).
+- Dates from xls files are now read as Python datetime objects (#373).
+- Allow import of "ragged" xlsx files (#465).
+
+### Improvements
+
+- When importing an xlsx file, Tablib will now read cell values instead of formulas (#462).
+
 ## 1.1.0 (2020-02-13)
 
 ### Deprecations
