flashing on Windows/MacOS machines **without having to install esphomeyaml**. So if esphomeyaml for some reason
can't find your USB port, you now can use the esphomeflasher app. See :ref:`esphomeflasher`.
- ESP8266s now save the states of lights/switches/... internally and restore them on boot. (:libpr:`258`)

- The :doc:`Over-the-Air Update </esphomeyaml/components/ota>` process was quite buggy sometimes and the Arduino-library
esphomelib used was doing some weird stuff. The OTA-process has now been completely re-written to be more stable

- You can now upload OTA firmware files with the :doc:`web server component </esphomeyaml/components/web_server>`
- Added the ability to define global variables in esphomeyaml: :ref:`config-globals`.
- Added a ``frequency`` option to the :doc:`/esphomeyaml/components/output/esp8266_pwm`.

- There can be a noticeable amount of flickering with increased WiFi activity.
- The output range only goes up to about 80%.
- It’s mostly fixed to a frequency of 1kHz, you can :ref:`increase this a
bit manually <esp8266_pwm-example_usage>` in code though.
If you need a stable PWM signal, it’s definitely recommended to use the
successor of the ESP8266, the ESP32, and its :doc:`ESP32 LEDC PWM <ledc>` instead.
