+* 0.1.0.0 -- 2021-11-18
+** First version. Released on an unsuspecting world.
+
+* 0.1.1.0 -- 2021-11-19
+** First addition to parsing capability
+
+* 0.1.3.0 -- 2021-11-21
+** Interactive mode is built only table mode remaining
+
+* 0.1.4.0 -- 2021-11-22
+** Table mode almost complete, bugs to be fixed by the next update
+
+* 1.0.0.0 -- 2021-11-25
+** Probably final update, table mode is still ridden with bugs and interactive mode is not as pleasant as it can be though other parts seem to be doing just fine
+
+* 2.0.0.0 -- 2022-03-23
+** Was not the final update, went though a major rewrite - still riddled with bugs though.
+  * Fixed a bunch of the parsing bugs
+  * Now added mode switching in interactive mode
+
+  ```text
+         :q -- Quit
+         :t -- Table Output
+         :l -- Latex Output
+         :s -- Raw Output
+         :f -- Fold formula to max
+         :F -- Specify number of folds to do
+         :h -- Help page
+         :d -- Subscript Output
+         :i -- Print options
+  ```
+  * Accidentally made table mode useless
