For 2.0, we still work, at least according to http://dev.mysql.com/doc/refman/5.1/en/show-slave-status.html (the new columns get mapped to the old one, not broken out). Since it would require a UI change, we should include support of these columns with other replication tab "polish" in 2.1.

Verified that as stated in http://dev.mysql.com/doc/refman/5.1/en/show-slave-status.html - the old Last_Errno and Last_Error are aliases for the new 5.1 Last_SQL_Errno and Last_SQL_Error so you will still get those as before. The new 5.1 Last_IO_Errno and Last_IO_Error are not aliased and will therefore need to be added.

per request from the reporter, we'll add those fields when they are present.

message:
add last_{sql|io}_err{no|or} support to the replication tab
and the replication server popups.
"last error" was renamed in all views to "last sql error" because
in pre 5.1 mysql's, it really was always the sql error, and i/o
errors were simply never shown.
in the case where the mysql server does not support both sql and io
servers, the io column is left blank in the tab, and in the popup
the rows are not even there.

An entry has been added to the 2.1.0 changelog: There were four columns added to the SHOW SLAVE STATUS query in MySQL Server 5.1: Last_IO_Errno, Last_IO_Error, Last_SQL_Errno, and Last_SQL_Error. However, these were not displayed within the Replication tab.
Description: There were 4 new columns added to SHOW SLAVE STATUS within 5.1: Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: These are not shown, nor accounted for, within the replication tab - they should probably be shown in the near future as more people move to 5.1 GA. How to repeat: Run MEM against a 5.1 slave. Check for the existence of anything relating to "Last_IO_Error" or "Last_SQL_Error" within the tab or popups. Suggested fix: Add in details for the SQL and IO thread Errors and Errnos.
