There will be another release today with breaking changes for developers onboarded to Tungsten.
This release has some internal changes which require all onboarded devs to install and use the 0.6.9 version of the SDK, which is currently not public.
You can install this version using the following command:
DFX_VERSION=0.6.9 sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"
Developers not onboarded to Tungsten will not be impacted. This release is set to happen at 3pm PST, at which point you will be able to install 0.6.9.
Please feel free to reach out to the team if you have questions or run into any issues.
