 ## Changelog
-Moved to [another location](changelog.md) as it became to prominent here. Only last three events are kept:
-* 26.02.2021: Shutdown via webgui is now available.
+Moved to [another location](changelog.md). Only last three events are kept:
 * 05.03.2021: Added support for remote control via infrared. Make sure to enable `IR_CONTROL_ENABLE` to use this feature and don't forget to assign corresponding rc-commands of *your* remote control to actions.
 * 19.03.2021: Added support for port-expander PCA9555. Can be used for everything, that is "button-like": buttons, headphone-detect, PN5180.IRQ.
+* 28.03.2021: Added support for fileseek. With commands `CMD_SEEK_FORWARDS` and `CMD_SEEK_BACKWARDS` it's possible to jump a number of seconds defined in `jumpOffset`.
 ## Known bugs
 * Some webstreams don't run. Guess it's a combination of saturated connection-pool and lack of heap-memory. Works probably better if ESP32-WROVER (e.g. Lolin D32 pro) is used, as this chip has PSRAM. Advice: Don't enable modules (e.g. MQTT) if you don't need them as this could save memory (and trouble).
 * English translation/version for webgui is currently pretty outdated. This will be fixed soon when i18n-support will be integrated.
