v0.20
- Fixed bugs with Windows 7 Eng.
- Implemented automatic restart of the application in case of any critical error.
- Added NBMiner support
- Changed profitability recalculation algorithm on nicehash pool
- Fixed minor bugs.

v0.21
- Added support for the new nicehash platform.
    old.nicehash.com (old platform).
    new.nicehash.com (new platform).
- Fixed a serious error leading to the inoperability of the program with unstable Internet.

P.S. Version 0.20 was very unsuccessful, due to large-scale internal changes in the program, the transition to new components, serious errors were made, unfortunately I noticed them after the release, so I highly recommend switching to the new version.
