• Type: New Feature
• Status: Resolved
• Priority: Major

Release Note

<!-- markdown -->
* The release notes now only contains JIRA issues with incompatible changes and actual release notes. The generated format has been changed from HTML to markdown.

* The changelog is now automatically generated from data stored in JIRA rather than manually maintained. The format has been changed from pure text to markdown as well as containing more of the information that was previously stored in the release notes.

* In order to generate the changes file, python must be installed.

* New -Preleasedocs profile added to maven in order to trigger this functionality.

Description

The current way we generate these build artifacts is awful. Plus they are ugly and, in the case of release notes, very hard to pick out what is important.
