The documentation available here https://jenkins.io/doc/book/pipeline/syntax/#post

doesn't mention the "aborted" post-condition action for post section but based on source code here https://github.com/jenkinsci/pipeline-model-definition-plugin/tree/a1963cdf49d71f1d81e6b668122138a0e4c90d99/pipeline-model-definition/src/main/groovy/org/jenkinsci/plugins/pipeline/modeldefinition/model/conditions

it's available for use (in case there is a need to do something when the job has been aborted for some reason).

Please could someone who has permissions update the docs ?

PS: Now it looks incomplete.
