[0.4.9] - 2021-06-13

add optional flag DHTLIB_VALUE_OUT_OF_RANGE

[0.4.8] - 2021-05-27

fixes to improve Arduino-lint

[0.4.7] - 2021-04-09

fix #60 negative temperatures below -25.5°C + readme.md

[0.4.6] - 2021-04-09

fix #57 negative temperatures DHT22
Do not use 0.4.5 and 0.4.4 as these are incorrect for negative temperature.

[0.4.5] - 2021-02-14

fix -0°C encoding of DHT22 ( bit pattern 0x8000 )

[0.4.4] - 2021-02-01

fix negative temperatures DHT22 (again)

[0.4.3] - 2021-01-13

add reset(), add lastRead()

[0.4.2] - 2020-12-15

fix negative temperatures

[0.4.1] - 2020-11-11

getType() attempts to detect sensor type
add Arduino -CI + readme

[0.4.0] - 2020-11-10

added DHTLIB_WAITING_FOR_READ as return value of read (minor break of interface)

[0.3.4] - 2020-09-23

Added waitFor(state, timeout) to follow timing from datasheet.
Restored disableIRQ flag as problems occurred on AVR. The default of this flag on AVR is false so interrupts are allowed.
This need some investigation
Fix wake up timing for DHT11 as it does not behave according datasheet.
fix wakeupDelay bug in setType();

[0.3.3] - 2020-08-18

fix #29, create explicit delay between pulling line HIGH and waiting for LOW in handshake to trigger the sensor.
On fast ESP32 this fails because the capacity / voltage of the long wire
cannot rise fast enough to be read back as HIGH.

[0.3.2] - 2020-07-17

fix #23 added get/setSuppressError(); overridable DHTLIB_INVALID_VALUE

[0.3.1] - 2020-07-08

added powerUp() powerDown();

[0.3.0] - 2020-06-12

added getReadDelay & setReadDelay to tune reading interval
removed get/setDisableIRQ; adjusted wakeup timing; refactor

[0.2.2] - 2020-06-08

added ERROR_SENSOR_NOT_READY and differentiate timeout errors

[0.2.1] - 2020-05-27

Fix #11 - Adjust bit timing threshold

[0.2.0] - 2020-05-02

made temperature and humidity private (Kudo's to Mr-HaleYa),

[0.1.7] - 2020-05-01

prevent premature read; add waitForReading flag (Kudo's to Mr-HaleYa),

[0.1.6] - 2020-04-09
