In the release notes for the new Portfolio planning experience, it references that Stages will no longer be supported, however it is quite vague whether this also refers to Skills as well.
Reference:
Stages and skills are not supported in the new experience for the following reasons:
There's low usage of stages across Portfolio plans.
Stages require regular, manual maintenance.
There's no way to integrate stages with Jira.
Usage of stages contradicts with the workflows in Jira.
Are both Skills AND Stages going to be removed? I am a heavy user of both of these, so it would be great to know the specifics on this.
