Release Date

June 12, 2018 (Final)

June 04, 2018 (Planned)


Important note about BLE and Bluetooth Mesh

NimBLE stack has been moved to separate repository. Initial release for NimBLE is 1.0 and is released together with Mynewt 1.4.

This is the only NimBLE release coupled with Mynewt release. From now on NimBLE will have own release schedule.

BLE sample applications are currently present in both -core and -nimble repos but will be removed from -core master branch shortly after release.

newt tool version 1.4 is required for upgrade to Apache Mynewt 1.4

Repositories dependency resolving was added in newt 1.4 and thus at least that version is required to perform upgrade to Apache Mynewt 1.4 release from older versions.
