Release 1.0.36

• Add variant files for e22 sx1262 (868 MHz module)
• Add ability to specify frequency limits for the module, so that settings will have correct minimum and maximum frequencies

Release 1.0.35

• By default, disable light sleep optimizations and introduce a separate PlatformIO target for building with light sleep optimizations. This new target can be utilized when the boost controller does not have automatic shutdown at low current.

Release 1.0.34

• Upgraded RadioLib to latest 7.5.0 version
• Introduced variant build structure for easier custom board extensions
• Set settings OPUS bit rate limit from 2400 bps to 16000 bps, lower than 2400 bps does not work, higher than 16000 is not practical for speech

Release 1.0.33

• Consume latest stable non-development Codec2 version

Release 1.0.32

• Power management optimizations:
  • Do not wakeup on BUSY line, so only incoming data can wakeup radio, but not any activity on the band
  • Lower esp32 frequency when entering sleep and restore when waking up, so periodic wakeup polling will run at minimum frequency

Release 1.0.31

• Increase recording high-pass filter cutoff frequency up to 300 Hz, this gives better speech quality and less wobbling on receiver side

Release 1.0.30

• Update libraries to latest versions, including RadioLib
• Fix issue with radio not going back to receive after receiving invalid packet, so user had to transmit first to get back to receive

Release 1.0.29

• Remove usage of additional ChaCha-Poly1305 auth data key as it is not needed and does not bring any benefit unless external/upper plain text protocol is used as auth data

Release 1.0.28

• Change ChaCha20-Poly1305 IV/NONCE size from 8 to 12 bytes to be compatible with other libraries and RFC8439, not interoperable with previous versions when privacy is enabled

Release 1.0.27

• Switch privacy from ChaCha20 to ChaCha20-Poly1305 to have message authentication, not interoperable with previous versions when privacy is enabled
