# Fixed

Browse Source 
- Illegible coloring of the Diff dialog.

# Implemented
- On-the-fly encryption and decryption in replication.
- Text splitting algorithms updated
(use a bit more memory (which is saved by On-the-fly enc-dec), but faster than old algorithms.)
- Garbage collector is now decent and memory saving.

# Internal things
- Refactored so much.
