+0.4.0 (2019-03-26)
+------------------
+    
+Since the last release the main improvements have been:
+
+ * Raise a custom exception instead of sysexiting when confronted with a wrong 
+   CSV file.
+ * Change prints for logger messages.
+ * Modularize the "get_tweets_from_csv" dividing it into 3 functions to provide
+   more isolated functions. Now this function makes use of 
+   "get_tweet_from_csv_line", which returns a single Tweet object when provided 
+   with two lists representing the contents of a CSV header and one of its
+   entries. There is also a "raw" alternative of that function, which works 
+   with raw lines and converts them to lists to then call the "non-raw" version.
+
+Version 4.1:
+The tweet-manager dependency, necessary for the core functions, has been added 
+into production (in setup.py).
