Thunderbird is a good rss reader in terms of being able to connect successfully to jira authenticated search feeds (where evolution-rss and Liferea can't), but really sucks when it comes to updating.
A Jira search feed will give a link id to http://jira/browse/[ticket no], and if that ticket/feed-item is updated, thunderbird refuses to update it - it already has it! (even though the item date does not match).
Also, if you delete the ticket update, it will never show up again for that news account.
Has anybody found an RSS reader that can work with JIRA/updating RSS items?
Note: this is not the same as Jira activity feeds - those work great, as each update has a unique item id
To replicate:
Grab a search (any search)
Get it into your rss reader
Read an item, modify the linked ticket
Update rss and see if the ticket bumps to most recent and unread
or, generically:
Get an rss feed (from your hard drive?)
Modify an item in the middle changing the content, the date, and moving it to the top
Update rss and see if the ticket bumps to most recent and unread
