At the time of this writing, the ASK CLI 2.6.0 has just been released. Along with it comes a fair bit of breaking changes the extend of which can be seen in this migration guide.
This has caused a fair bit of challenge in the community especially for developers who have multiple skills prior to ASK CLI 2.x being introduced. A lot of automation tools would also have to be rewritten and some even have no viable workarounds when using 2.x. The VSCode extension functionality that allows convenient ASK CLI support is also broken.
