Release 3.5

• version bump
• increase attiny/atmega hasher hash rate

Release 3.3

This release incorporated many new features with user friendliness in mind

• added internal temperature reporting for ATTiny, ATMEGA328 (user to perform calibration if needed)
• better documentation of ATTiny setup and use case description
• support LED brightness control (Thanks Kaiechi!)
• boost ATTiny hashrate to 267H/s while saving 30% program storage
• support WDT in ATTiny
• optimized worker capability query on startup

Release 3.2

This release marked a new milestone on I2C Duino-Coin mining for Raspberry Pi Pico.
Tremendous effort went into improving I2C handling and error correction.
New feature introduce includes:

• Pico IoT
• Pico dual core dual I2C
• Pico 1MHz I2C SCL clock frequency
• Pico unique DUCOID
• Python miner avr timeout auto adjust based on job diff
• worker CRC8 status auto-discovery

Note: please update worker sketch to allow Python miner to work properly

Release 3.0

• Improved Arduino hashrate (37% more hashrate)
• Improved Pico hashrate (60% more hashrate)
• Deprecated Arduino_Slave in favor of Tiny_Slave
• Added option to disable CRC8 feature
• Added 60s delay start gap for each worker to help with Kolka efficiency sync
• Pulled in enhancement from official duino-coin github

support attiny and pico
