 ### Changed 
 - Unified the directories `cookbooks/` and `doc/sphinx/user_manual/cookbooks`. All information about cookbooks including the documentation is now bundled in the top-level `cookbooks/` directory. \[Rene Gassmoeller; 2024-02-14; [#558](github.com/GeodynamicWorldBuilder/WorldBuilder/pull/558)\]
+- Deleted the deprecated Latex manual. Use the new sphinx documentation instead, which can be build into a .pdf file as well. \[Rene Gassmoeller; 2024-02-14; [#595](https://github.com/GeodynamicWorldBuilder/WorldBuilder/pull/595)
 - Relocated the code that is used to calculate spreading center quantities like distance from the ridge, and spreading rate. Currently the spreading rate is just a constant value, but this will be changed in a follow up pull request. \[Daniel Douglas; 2024-02-14; [#590](https://github.com/GeodynamicWorldBuilder/WorldBuilder/pull/590)
