I'm going to be lazy and just paste in the release notes. I'm watching the trampoline event at the Olympics while I do this - and you know what? The trampoline is freaking cool. Anyway, here is the 001 release for 5.9.1:
/client/stats.cfm - Oracle fixes (thanks to Steven Tomcavage)
/client/index.cfm - Forgot to use #application.rooturl# in podcasting support - thanks to Marion Bass
/org/camden/blog/blog.cfc - Include author name in emails
/install/mysql.sql - Changed the text fields in entries (body, morebody) to longtext. It may be a good idea for you to manually update your table.
/xmlrpc/xmlrpc.cfm - when deleting, clear cache
/client/tags/textarea.cfm - make the custom tag correctly handle a closing tag
/client/admin/page.cfm - Use the textarea custom tag. For those who modded textarea to use an RTE, it adds RTE to the page editor.
