But that one was just a starter and there remain a lot of issues to > be solved. I'm planing to solve at least some of them. > All fixes and improvements are targeting the non-sequential parser and I > won't port those changes to the old parser. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
