Wondering what this update incurs. What is "fix lost modified date when using keep/ignore tags? And "added Visible Y/N field to categories? Please let me know, as I do not know if this could be critical for us or not.
If you are using Keep/Ignore tags then the modification date of the page was being set to the current time rather than the time the webserver indicated. This could throw off "order by date" and the display of the modification date.
When specifying categories you can now indicate if they should show up in the drop down list or not. For example if you have a large number of categories you may only want some of them visible.
