May 22th 2019: Device OS v1.2.1-rc.1

A new Release Candidate Device OS v1.2.1-rc.1 is available now on https://build.particle.io for Core/Photon/P1/Electron/Argon/Boron/Xenon/A SoM/B SoM/X SoM.


1.2.1-rc.1


:information_source: Note: This is primarily a Manufacturing release for Gen 3 devices with no significant feature/enhancement/bugfixes. Your testing is appreciated though. If you find any issues, please report them, and fallback to 1.2.0-rc.1 or 1.1.0.


Note: If your Gen 3 device does not have a Cloud connection, it is recommended to update system firmware, and then the bootloader via CLI with particle flash --serial bootloader.bin (bootloaders found in Github release)

This release contains v310 bootloaders (bumped this release due to Gen 3 changes in #1768 ). We have also separated BOOTLOADER_DEPENDENCY for Gen 2 and Gen 3. For now, we will leave Gen 2 as is depending on v201 bootloader (so there is nothing to do for Gen 2 (Photon/P1 only) unless you want the latest bootloader, although it is not mandatory), but we have bumped Gen 3 to v302 because also in this release we have removed the embedded bootloaders from Gen 3 system firmware. To force the Cloud update for Gen 2 (Photon/P1 only) we will bump the bootloader dependency version to v302 in v1.2.0 default.
