The changes were as follows:
- Refined Search, including having exact phrase and keyword results display
- Adjusted Screens to have newly added screens display at the top
- Added role-based content capability (e.g., if you are serving in a bishopric, you can now access Handbook 1)
- Fixed various bugs and stability issues
After updating and looking around the app here are my thoughts:
First off I was very happy that this update did not go back to causing the headache of redownloading all of the content you might have downloaded before. This update appears to have kept all of the data stored in the app previously.
