Release Date

August XX, 2023 (Final)

August XX, 2023 (Planned)

Important Notes

Due to various issues with shallow cloning newt 1.11 no longer default to it. One needs to explicitly select shallowness level with --shallow= option.

New Features

Support for external modules

Some external projects are now used as external modules (under repos) as oppose to keeping local copy in tree. This greatly reduces codebase size

(over 4 millions lines of code were removed, sic!) and allows for easier upgrade and management of external code. 

MSC FAT view support

New msc_fat_view package allows to perform firmware upgrade over USB when Mynewt device is visible as FAT disk.Drivers

  • bmp390
  • pic32mz ETH peripheral

mbedTLS updated to 2.28.4

nrfx updated to 2.11.0

STMs HAL update

Multiple STM HALs were updated (as external modules).

LVGL integration and support for touch screens

It is now possible to use LVGL along with various TFT touchscreen for GUI applications.

Selectable download scripts

On multiple BSPs it is now possible to selected download script used eg. on Nordic chips one can use jlink or nrfjprog scripts.

LittleFS updated to version 2.5.0

Newlib-nano support

it is now possible to use newlib-nano instead of (default) baselibc standard library.
