Serial Monitor Constantly Spits out Deprecation Error

When attached to the serial monitor, the logs are flooded with a print buffer deprecation error, here is an example of the logs from boot (DevEUI, AppEUI, AppKey & location redacted):

These repeat messages make it impossible to see any notification of transmissions on the device screen as they are cleared instantly with these other messages. Defining release_eu868 in PlatformIO.ini from feature/web branch, downloading locally as ZIP "<> Code". Download was created today. This is on Lilygo TTGO TBeam v1.2. Device transmits packets no problem to Chirpstack/Console.
