So this release only has changes to work with the display TTGO is using in production for their T-Echo NRF52840/SX1262/Eink product. You don’t need to upgrade if you are already running 1.2.39.
Dear TTGO congrats on shipping your board! The application load you can use for programming is “firmware-t-echo-22.214.171.124f3682.uf2”
