This release primarily improves OTAA Join handling in the modem:
- OTAA Join requests are [automatically retransmitted](https://github.com/hardwario/lora-modem-abz/wiki/AT-Command-Interface#atjoin) up to eight times;
- The counter values returned by `AT+FRMCNT` after OTAA Join [match](https://github.com/hardwario/lora-modem-abz/wiki/AT-Command-Interface#atfrmcnt) the original Murata Modem firmware;
- DevNonce is [preserved](https://github.com/hardwario/lora-modem-abz/wiki/AT-Command-Interface#atfacnew), making it possible for the device to rejoin the network after a factory reset;
- The command [`AT+JOINDC`](https://github.com/hardwario/lora-modem-abz/wiki/AT-Command-Interface#atjoindc) can be used to enable or disable OTAA Join duty cycling.
This release also includes the following minor improvements:
- `AT$VER` was switched to a machine readable format with [additional information](https://github.com/hardwario/lora-modem-abz/wiki/AT-Command-Interface#atver-1) in the output;
- LoRAWAN certification port is disabled by default, but can be enabled with [`AT$CERT`](https://github.com/hardwario/lora-modem-abz/wiki/AT-Command-Interface#atcert).
