Pipelines Access to JIRA Version

I realize that JIRA integration is still MIA, but I wanted to voice my desire for the following two things:

1.) Ability to trigger a Pipelines build from JIRA Build and Release.
2.) Ability to access the version information, possibly as a Pipelines environment variable within bitbucket-pipelines.yml. With Bamboo, I am able to access this information using ${bamboo.jira.version}, so I'd be looking for something similar in Pipelines.

(I am mentioning both issues at once, because in Bamboo, ${bamboo.jira.version} is only available when I build from a JIRA release.)
