v0.2.0

Release Highlights

• DTR and Ring Indicator pins replace power and indicate pins.
• Refactoring of socket API. All commands now take a socket handle. Also adding support for hexadecimal sending and receiving.
• Changed default AT command terminator to CR.
• Optimized PPP/CMUX and Cellular Modem driver implementations to support proper power saving. A sample to be introduced in the next release.
• Added generated documentation.
• Removed support for nrf9160dk, nrf9161dk, nrf9131ek and thingy91 board targets.
• Removed the following features: Native TLS, TCP/UDP servers, HTTP client, FTP, GPIO, TWI/I2C
