# Changelog
|
||||
|
||||
## 0.2.1
|
||||
|
||||
### Changed
|
||||
- performance improvement: internally `get_difficulty` was being called
|
||||
multiple times while generating `PoW`, now it calls only once.
|
||||
|
||||
## 0.2.0
|
||||
|
||||
### Changed
|
||||
- Difficulty factor is now an unsigned 32 bit number
|
||||
|
||||
## 0.1
|
||||
|
||||
### Added:
|
||||
- PoW constructor
|
||||
- unique salt
|
||||
|
||||
## 0.2
|
||||
- Difficulty factor is now an unsigned 32 bit number
