. I tested on many boards and it was released as Arduino Ethernet version 2.0.0.

PROJECT DESCRIPTION
Improved Performance Ethernet Library
Wiznet chips W5100, W5200 and W5500 are automatically detected.
Efficient block mode of W5200 & W5500 are used for data and multi-byte register access.
Wiznet socket registers are cached, which greatly reduces SPI communication overhead, at the cost of a small increase in RAM usage. TCP connections and UDP packets accessed in small chunks typically see a substantial performance boost.
Adafruit's Ethernet.init(CSPIN) extension is supported, to allow use of different pins for the chip select signal. Optimized direct register I/O is used for most Arduino compatible boards.
