Subject [jira] Commented: (LUCENE-1708) Improve the use of isDeleted in the indexing code
Date Thu, 02 Jul 2009 17:13:47 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12726563#action_12726563

Mark Miller commented on LUCENE-1708:
-------------------------------------

I suppose, to be fair, we do mention that we might change runtime behaviour and document it
- its just that we don't usually say, code around it.

I guess its simple enough here thats its not really a big deal. I was just surprised I saw
no mention of back compat in the discussion other than Mike mentioning that the change should
be made through deprecation early on in the attached email thread.
