#### 4.1.1.2. bblayers.conf

The `meta-yocto` layer has been split into two parts: `meta-yocto` and `meta-yocto-bsp`, corresponding to the Poky reference distro configuration and the reference hardware Board Support Packages (BSPs), respectively. When running BitBake or Hob for the first time after upgrading, your `conf/bblayers.conf` file will be updated to handle this change and you will be asked to re-run/restart for the changes to take effect.
