Release 1.6.0
- Solved bugs found on merkle root calculations. - Solved issues about difficulty calculation - Tested on low difficulty pools. - Changed the default pool to http://public-pool.airdns.org/ - Added new notes to readme about supported pools - Added new custom sha tests to use on next versions
