 This library enables you to **send _and_ receive** infra-red signals on an [ESP8266](https://github.com/esp8266/Arduino) or an
 [ESP32](https://github.com/espressif/arduino-esp32) using the [Arduino framework](https://www.arduino.cc/) using common 940nm IR LEDs and common IR receiver modules. e.g. TSOP{17,22,24,36,38,44,48}* demodulators etc.
 
-## v2.7.4 Now Available
-Version 2.7.4 of the library is now [available](https://github.com/crankyoldgit/IRremoteESP8266/releases/latest). You can view the [Release Notes](ReleaseNotes.md) for all the significant changes.
+## v2.7.5 Now Available
+Version 2.7.5 of the library is now [available](https://github.com/crankyoldgit/IRremoteESP8266/releases/latest). You can view the [Release Notes](ReleaseNotes.md) for all the significant changes.
 
 #### Upgrading from pre-v2.0
 Usage of the library has been slightly changed in v2.0. You will need to change your usage to work with v2.0 and beyond. You can read more about the changes required on our [Upgrade to v2.0](https://github.com/crankyoldgit/IRremoteESP8266/wiki/Upgrading-to-v2.0) page.

 Cette librairie vous permetra de **recevoir et d'envoyer des signaux** infrarouge sur le protocole [ESP8266](https://github.com/esp8266/Arduino) ou sur le protocole
 [ESP32](https://github.com/espressif/arduino-esp32) en utilisant le [Arduino framework](https://www.arduino.cc/) qui utilise la norme 940nm IR LEDs et le module basique de reception d'onde IR. Exemple : TSOP{17,22,24,36,38,44,48}* modules etc.
